Port Settings

SUMMARY Learn about how to channelize speeds on different ports, configure port type, and configure system mode on switches.

Channelize Block of Ports or Individual Port

You can either configure a port as a single interface (non channelized interface) or partition the port into smaller data channels or multiple interfaces (channelized interfaces). On switches platform, you can channelize an individual port or block of ports or quad ports based on the platform.

Table 1 describes the steps to follow in channelizing a port and setting the port speed.

Table 1: Channelize block of ports or individual port

Configuration Steps

Details

Example

Channelize Individual Port: Configure an individual port to operate at a specific channel speed. Specify a port number and channel speed.

[edit chassis fpc fpc-slot pic pic-slot]
user@switch# set port port-number channel-speed speed

To configure an individual 40-Gigabit Ethernet (et) port to operate as 10-Gigabit Ethernet (xe) ports, specify a port number and channel speed

[edit chassis fpc 0 pic 0]
user@switch# set port 3 channel-speed 10g

Channelize Block of Ports: Channelize a block of ports. Specify a port range and channel speed.

[edit chassis fpc fpc-slot pic pic-slot]
user@switch# set port-range port–range-low port-range-high channel-speed speed

To configure ports 0 through 3 on PIC 0 to operate as 50-Gigabit Ethernet ports:

[edit chassis fpc 0 pic 0]
user@switch# set port-range 0 3 channel-speed 50g

Configure Speed per Quad: Configure port speeds only per quad (group of 4 ports) and not individually. Specify the speed for the first port of the quad ports. All ports operate at a single speed within the quad.

[edit chassis fpc fpc-slot pic pic-slot]
user@switch# set port port–number speed speed

To configure ports 4 through 7 to operate as 25-Gigabit Ethernet ports, you must configure port 4 to operate as 25-Gigabit Ethernet ports.

[edit chassis fpc 0 pic 0]
user@switch# set port 4 speed 25g 

(Optional) Return to default configuration, for an individual port or quad ports.

[edit chassis fpc fpc-slot pic pic-slot]
user@switch# delete port-number speed speed
[edit chassis fpc 0 pic 0]
user@switch# delete 4 speed 25G

(Optional) Return to default configuration, for block of ports.

[edit chassis fpc fpc-slot pic pic-slot]
user@switch# delete port-range port-range-low port-range-high channel-speed speed

To return ports 0 through 3 from the 50-Gigabit Ethernet configuration to the default 100-Gigabit Ethernet configuration:

[edit chassis fpc 0 pic 0]
user@switch# delete port-range 0 3 channel-speed 50g

Commit the configuration.

Table 2 describes the steps to configure the port speed for channelized and non-channelized interfaces from the [edit interfaces] hierarchy.

Table 2: Port Speed Configuration for Non-channelized Interfaces and Channelized Interfaces - Interfaces Hierarchy

Configuration Steps

Non-Channelized Interfaces

Channelized Interfaces

Step 1: To indicate the speed at which the ports operate, configure the speed statement for the desired interfaces.

[edit interfaces interface-name]
user@host# set speed (10G | 25G | 40G | 50G| 100G | 400G)

For example:

[edit interfaces et-1/0/3]
user@host# set speed 100g
[edit interfaces interface-name]
user@host# set speed (10G | 25G | 40G | 50G| 100G | 400G)

For example:

[edit interfaces et-1/0/3]
user@host# set speed 100g

Step 2: To configure the speed for a group of ports.

[edit ]
user@host# wildcard range set interfaces interface-name speed speed

For example:

[edit ]
user@host# wildcard range set interfaces et-1/0/[0-5] speed 100g 
[edit ]
user@host# wildcard range set interfaces interface-name speed speed

For example:

[edit ]
user@host# wildcard range set interfaces et-1/0/[7-12] speed 100g 

Step 3: To specify the number of interfaces you want to configure per port.

Not applicable

[edit interfaces interface-name]
user@host# set number-of-sub-ports number-of-sub-ports

For example:

[edit interfaces et-1/0/3]
user@host# set number-of-sub-ports 4

In this example, in Step 1 and Step 2, you configure 4x100GE channelized interfaces.

Step 4: (Optional) To control the number of interfaces created on a physical port, use the unused statement. If you configure a port as unused, no interfaces are created for that port irrespective of the port profile configuration for that port.

[edit]
user@host# set interfaces interface-name unused 

For example:

[edit]
user@host# set interfaces et-2/0/3 unused

In this example, no interfaces (channelized or non-channelized) are created on port 3 of the line card installed in the FPC slot 2.

[edit]
user@host# set interfaces interface-name unused 

For example:

[edit]
user@host# set interfaces et-2/0/4 unused

In this example, no interfaces (channelized or non-channelized) are created on port 4 of the line card installed in the FPC slot 2.

Step 5: Verify the configuration.

et-x/y/z { 
speed 100g;
 
 unit 0 { 
    ...
 } 
  ... 

 unit N {
    ... 
 }

}
...
et-x/y/z { 
unused;
 
 
et-x/y/z { 
speed 100g;
 number-of-sub-ports 4;

 et-x/y/z:0 { 
   unit 0{ 
 ...
	} 
 }

et-x/y/z:1 { 
   unit 0{ 
 ...
	} 
 }

et-x/y/z:2 { 
   unit 0{ 
 ...
	} 
 }

et-x/y/z:3 { 
   unit 0{ 
 ...
	} 
 }

...
et-x/y/z:6 { 
unused;
 
 

Step 6: Commit the configuration.

Interface Naming Conventions

Each interface name includes a unique identifier and follows a naming convention. When you configure the interface, use the interface name. You can either configure a port as a single interface (non channelized interface) or partition the port into smaller data channels or multiple interfaces (channelized interfaces).

When multiple interfaces are supported on a physical port, you use the colon (:) notation in the interface naming conventions as a delimiter to differentiate the multiple interfaces on a physical port. In the interface naming convention, xe-x/y/z:channel:

  • x refers to the FPC slot number.

  • y refers to the PIC slot number.

  • z refers to the physical port number.

  • channel refers to the number of channelized interfaces.

When the 40-Gigabit Ethernet interfaces (et-fpc/pic/port) are channelized as 10-Gigabit Ethernet interfaces, the interface appears in the xe-fpc/pic/port:channel format, and channel is a value of 0 through 3.

Table 3 describes the naming formats for the channelized and non-channelized interfaces.

Channelizing Interfaces on QFX3500, QFX3600, QFX5100, QFX10002, QFX10008, QFX10016, and EX4600 Switches

Note:

On QFX10008 and QFX10016 switches, channelization is supported on fiber break-out cables using standard structured cabling techniques.

Note:

On QFX10002 switches running on Junos OS Release 15.1X53-D10 or Junos OS Release 15.1X53-D15, when you delete and then reapply channelized interfaces, traffic is disrupted and might not be recovered.

The QFX3500, QFX3600, QFX5100, and EX4600, QFX10002, QFX10008, and QFX10016 switches provide 40-Gbps QSFP+ ports that can be channelized. Channelization allows you to configure 40-Gbps QSFP+ ports to operate as four 10-Gigabit Ethernet (xe) interfaces. (Platform support depends on the Junos OS release in your installation.) You can use QSFP+ to four SFP+ breakout cables or QSFP+ transceivers with fiber breakout cables to connect the 10-Gigabit Ethernet ports to other servers, storage, and switches. By default, the four 40-Gbps QSFP+ ports operate as 40-Gigabit Ethernet (et) ports. When an et port is channelized to four xe ports, a colon is used to signify the four separate channels. For example, on a switch with port 2 on PIC 1 configured as four 10-Gigabit Ethernet ports, the interface names are xe-0/1/2:0, xe-0/1/2:1, xe-0/1/2:2, and xe-0/1/2:3.

By default, the 40-Gbps QSFP+ ports on EX4600 and QFX5100 switches are channelized automatically (auto-channelized) if any of the four channels on a 40-Gbps QSFP+ port receive data, unless you have configured channelization either at the chassis level or at the port level. Auto-channelization is not supported on interfaces contained in expansion modules, or on Virtual Chassis ports.

Note:

If you are using a EX4600 or QFX5100 switch with a peer QFX10000 switch, you must disable auto-channelization on the EX4600 or QFX5100 switch to ensure that the relevant interfaces are created and the links are up.

You can disable auto-channelization by including the disable-auto-speed-detection statement at the [edit chassis fpc slot-number pic pic-number (port port-number | port-range port-range-low port-range-high) channel-speed] hierarchy.

There are restrictions on the ports you can channelize on the QFX5100-24Q and QFX5100-96S switches, depending on the system mode you enable. If you try to channelize ports that are restricted, the configuration is ignored. See Configuring the System Mode for more information.

On QFX10002, QFX10008, and QFX10016 switches, there are 100-Gigabit Ethernet ports that work either as 100-Gigabit Ethernet or as 40-Gigabit Ethernet, but are recognized as 40-Gigabit Ethernet by default. You cannot channelize the 100-Gigabit Ethernet ports when they are operating as 100-Gigabit Ethernet interfaces. The 40-Gigabit Ethernet ports can operate independently or be channelized into four 10-Gigabit Ethernet ports as part of a port range. Ports cannot be channelized individually. Only the first and fourth port in each 6XQSFP cage is available to channelize as part of a port range. In a port range, the ports are bundled with the next two consecutive ports. For example, if you want to channelize ports 0 through 2, you would channelize port 0 only. If you try to channelize a port that is not supported, you will receive an error message when you commit the configuration. Auto-channelization is not supported on any ports.

When a 40-Gigabit Ethernet transceiver is inserted into a 100-Gigabit Ethernet port, the port recognizes the 40-Gigabit Ethernet port speed. When a 100-Gigabit Ethernet transceiver is inserted into the port and enabled in the CLI, the port recognizes the 100-Gigabit Ethernet speed and disables two adjacent 40-Gigabit Ethernet ports.

Table 4 provides detailed information on which ports are 100-Gigabit Ethernet, which ports can be channelized, and which ports are disabled when a 100-Gigabit Ethernet is inserted in the QFX10002-36Q switch and the QFX10000-36Q line card on a QFX10008 or QFX10016 switch. Table 5 provides detailed information on which ports are 100-Gigabit Ethernet, which ports can be channelized, and which ports are disabled when a 100-Gigabit Ethernet is inserted in the QFX10002-72Q switch. On the QFX10008 and QFX10016 switches with the QFX10000-36Q line card installed, only ports 0 through 35 are available. For more information, see QFX10002-72Q Port Panel and QFX10000-36Q Line Card.

The following steps describe how to configure a block of ports or an individual port to operate as 10-Gigabit Ethernet ports.

  1. To configure a block of 40-Gigabit Ethernet (et) ports on QFX3500, QFX3600, QFX5100, EX4600 switches to operate as 10-Gigabit Ethernet ports, specify a port range and channel speed:

    For example, to configure ports 0 through 3 on PIC 1 to operate as 10-Gigabit Ethernet ports:

  2. To configure a range of ports on a QFX10002-72Q, QFX10008, or QFX10016 switch to operate as 10-Gigabit Ethernet ports:
    Note:

    The port-range statement is not available on QFX10002-72Q, QFX10008, and QFX10016 switches. Instead, configure the port range using the port statement. Starting from port 0, you channelize every third port to channelize a group of three ports. For example, channelize port 0 to channelize ports 0 through 2, port 3 to channelize ports3 through 5, and so on. See Table 4 for port mapping information.

    For example, to configure ports 0 through 2 on PIC 0 to operate as 10-Gigabit Ethernet ports:

    Note:

    When you channelize port 0, ports 1 and 2 are also channelized.

  3. To configure an individual 40-Gigabit Ethernet (et) port on QFX3500, QFX3600, QFX5100, and EX4600 switches to operate as 10-Gigabit Ethernet (xe) ports, specify a port number and channel speed:

    For example, to configure port 3 to operate as 10-Gigabit Ethernet ports:

  4. Review your configuration and issue the commit command.
  5. To return a range of ports on QFX3500, QFX3600, QFX5100, and EX4600 switches to the default 40-Gigabit Ethernet configuration, delete the 10g statement:

    For example, to return ports 0 through 3 to the default 40-Gigabit Ethernet configuration:

  6. To return a range of ports on QFX10002-72Q, QFX10008, or QFX10016 switches to the default 40-Gigabit Ethernet configuration, delete the 10g statement:

    For example, to return ports 0 through 2 to the default 40-Gigabit Ethernet configuration:

  7. Review your configuration and issue the commit command.
  8. To return a port on QFX3500, QFX3600, QFX5100, and EX4600 switches to the default 40-Gigabit Ethernet configuration, delete the 10g statement:

    For example, to return port 2 to the default 40-Gigabit Ethernet configuration:

  9. Review your configuration and issue the commit command.

The following steps describe how to disable auto-channelization at the port level on QFX3500, QFX3600, QFX5100, and EX4600 switches .

  1. To disable auto-channelization at the port level, include the disable statement:

    For example, to disable auto-channelization for one port:

    For example, to disable auto-channelization for a range of ports:

  2. Review your configuration and issue the commit command.

Channelizing Interfaces on QFX5110-48S Switches

On the QFX5110-48S switch, there are four ports labeled 48 through 51, which support QFSP28 ports. The QSFP28 ports support 100-Gigabit Ethernet interfaces and 40-Gigabit Ethernet interfaces. You can channelize the 40-Gigabit Ethernet interfaces to four independent 10-Gigabit Ethernet interfaces using breakout cables.

Note:

You cannot configure channelized interfaces to operate as Virtual Chassis ports.

When you channelize the 40-Gigabit Ethernet interfaces as 10-Gigabit Ethernet interfaces, the interface names appear in the xe-fpc/pic/port:channel format, where channel can be a value of 0 through 3. To channelize the ports, manually configure the port speed using the set chassis fpc slot-number port port-number channel-speed speed command, where the speed can be set to 10G. The ports do not support auto-channelization.

Note:

On QFX5110-48S standalone switches, the FPC value is always 0.

Starting in Junos OS release 20.1R1, in addition to 1-Gbps, 10-Gbps, 40-Gbps, 100-Gbps speeds, now you can also configure 100-Mbps speed using the set interfaces interface-name speed 100M command. By default, all 48 ports on QFX5110-48S come up with 10-Gbps speed. With QFX-SFP-1GE-T connected, along with 1-Gbps speed, now you can also configure 100-Mpbs on QFX5110-48S switches.

The following steps describe how to channelize blocks of ports or individual ports:

  1. To configure an individual 40-Gigabit Ethernet (et) port to operate as 10-Gigabit Ethernet (xe) ports, specify a port number and channel speed:

    For example, to configure port 48 to operate as 10-Gigabit Ethernet ports:

  2. Review your configuration and issue the commit command.
  3. To return a range of ports from the 10-Gigabit Ethernet configuration to the 40-Gigabit Ethernet configuration, delete the 10g statement:

    For example, to return ports 48 through 51 from the 10-Gigabit Ethernet configuration to the 40-Gigabit Ethernet configuration:

  4. Review your configuration and issue the commit command.
  5. To return an individual 10-Gigabit Ethernet port to the 40-Gigabit Ethernet configuration, delete the 10g statement:

    For example, to return port 48 from the 10-Gigabit Ethernet configuration to the 40-Gigabit Ethernet configuration:

  6. Review your configuration and issue the commit command.

Channelizing Interfaces on QFX5200-32C Switches

You can channelize the 100-Gigabit Ethernet interfaces to two independent 50-Gigabit Ethernet or to four independent 25-Gigabit Ethernet interfaces. The default 100-Gigabit Ethernet interfaces can also be configured as 40-Gigabit Ethernet interfaces, and in this configuration can either operate as dedicated 40-Gigabit Ethernet interfaces or can be channelized to four independent 10-Gigabit Ethernet interfaces using breakout cables.

Note:

You cannot configure channelized interfaces to operate as Virtual Chassis ports.

On the QFX5200-32C switch, there are a total of 32 physical ports. Any port can be used as either 100-Gigabit Ethernet or 40-Gigabit Ethernet interfaces. You choose the speed by plugging in the appropriate transceiver. They can also be channelized to 50G, 25G or 10G.

By default, the 100-Gigabit Ethernet and 40-Gigabit Ethernet interfaces appear in the et-fpc/pic/port format. When the 100-Gigabit Ethernet interfaces are channelized as 50-Gigabit Ethernet and 25-Gigabit Ethernet interfaces, the interface names appear in the et-fpc/pic/port:channel format. When the 40-Gigabit Ethernet interfaces are channelized as 10-Gigabit Ethernet interfaces, the interface names appear in the xe-fpc/pic/port:channel format, where channel can be a value of 0 through 3. To channelize the ports, manually configure the port speed using the set chassis fpc slot-number port port-number channel-speed speed command, where the speed can be set to 10G, 25G, or 50G. If a 100-Gigabit Ethernet transceiver is connected, you can only set the speed to 25G or 50G. If a 40-Gigabit Ethernet transceiver is connected, you can only set the speed to 10g. There is no commit check for this, however.

On the QFX5200-32C switches, the ports support auto-channelization starting in Junos OS Release 15.1X53-D230.

Note:

For details about supported transceivers and cable specifications, see the QFX5200 Switch Hardware Guide.

Note:

On QFX5200-32C standalone switches, the FPC value is always 0.

The following steps describe how to channelize blocks of ports or individual ports.

  1. To configure a block of 100-Gigabit Ethernet (et) ports to operate as 50-Gigabit Ethernet ports, specify a port range and channel speed:

    For example, to configure ports 0 through 3 on PIC 0 to operate as 50-Gigabit Ethernet ports:

  2. To configure a block of 100-Gigabit Ethernet (et) ports to operate as 25-Gigabit Ethernet ports, specify a port range and channel speed:

    For example, to configure ports 0 through 3 on PIC 0 to operate as 25-Gigabit Ethernet ports:

  3. To configure an individual 40-Gigabit Ethernet (et) port to operate as 10-Gigabit Ethernet (xe) ports, specify a port number and channel speed:

    For example, to configure port 3 to operate as 10-Gigabit Ethernet ports:

  4. Review your configuration and issue the commit command.
  5. To return a range of ports from the 50-Gigabit Ethernet configuration to the default 100-Gigabit Ethernet configuration, delete the 50g statement:

    For example, to return ports 0 through 3 from the 50-Gigabit Ethernet configuration to the default 100-Gigabit Ethernet configuration:

    Note:

    To configure the ports to another channel-speed, you must delete the current port-range statement to return to the default 100-Gigabit Ethernet configuration.

  6. Review your configuration and issue the commit command.

Channelizing Interfaces on QFX5210-64C Switches

You can channelize the 100-Gigabit Ethernet interfaces to two independent 50-Gigabit Ethernet or to four independent 25-Gigabit Ethernet interfaces. The default 100-Gigabit Ethernet interfaces can also be configured as 40-Gigabit Ethernet interfaces, and in this configuration can either operate as dedicated 40-Gigabit Ethernet interfaces or can be channelized to four independent 10-Gigabit Ethernet interfaces using breakout cables.

On the QFX5210-64C switch, there are a total of 64 physical ports. Any port can be used as either 100-Gigabit Ethernet or 40-Gigabit Ethernet interfaces. You choose the speed by plugging in the appropriate transceiver. QFX5210-64C switches can also be channelized to 50G, 25G or 10G. QFX5210-64C switch supports three port speeds in total, 10-Gbps, 40-Gbps, and 100-Gbps. It supports native 40, 100-Gigabit Ethernet configuration and channelized 10, 25, 50-Gigabit Ethernet configuration.

Starting in Junos OS Release 19.1R1, you can channelize the 100-Gigabit Ethernet interfaces to four independent 25-Gigabit Ethernet interfaces or two independent 50-Gigabit Ethernet interfaces. Based on the optics used, the 100-Gigabit Ethernet or 40-Gigabit Ethernet interface is supported. The default 100-Gigabit Ethernet interfaces can also be configured as 40-Gigabit Ethernet interfaces. This configuration can either operate as dedicated 40-Gigabit Ethernet interfaces, or can be channelized to four independent 10-Gigabit Ethernet interfaces using breakout cables on the QFX5210-64C switch. You can use all the available ports on QFX5210-64C switch without disabling the ports. The port channelization on QFX5210 switches occurs automatically when the total number of ports does not exceed 128 BCM ports and when the number of port per pipe does not exceed 32 BCM ports.

By default, the 100-Gigabit Ethernet and 40-Gigabit Ethernet interfaces are displayed in the et-fpc/pic/port format. When the 100-Gigabit Ethernet interfaces are channelized as 50-Gigabit Ethernet and 25-Gigabit Ethernet interfaces, the interface names appear in the et-fpc/pic/port:channel format. When the 40-Gigabit Ethernet interfaces are channelized as 10-Gigabit Ethernet interfaces, the interface names appear in the xe-fpc/pic/port:channel format.

To channelize the ports, manually configure the port speed using the set chassis fpc slot-number port port-number channel-speed speed command, where the speed can be set to 10G, or 25G, or 50G. If a 100-Gigabit Ethernet transceiver is connected, you can only set the speed to 25G or 50G. If a 40-Gigabit Ethernet transceiver is connected, you can only set the speed to 10G. There is no commit check for this, however.

Note:

For details about supported transceivers and cable specifications, see the QFX5200 Switch Hardware Guide.

The following steps describe how to channelize blocks of ports or individual ports.

  1. Configure a block of 100-Gigabit Ethernet (et) ports to operate as 50-Gigabit Ethernet ports, by specifying the port range and channel speed:

Channelizing Interfaces on QFX5120-48Y Switches

You can channelize the 100-Gigabit Ethernet interfaces to four independent 25-Gigabit Ethernet interfaces. The default 100-Gigabit Ethernet interfaces can also be configured as 40-Gigabit Ethernet interfaces, and in this configuration can either operate as dedicated 40-Gigabit Ethernet interfaces or can be channelized to four independent 10-Gigabit Ethernet interfaces using breakout cables.

Note:

You cannot configure channelized interfaces to operate as Virtual Chassis ports.

On the QFX5120 switch, there are a total of 56 ports. Of these 56 ports, 8 ports (labeled 48 through 55) are uplink ports that support 100-Gigabit Ethernet interfaces (QSFP28 ports) and 40-Gigabit Ethernet interfaces (QSFP+ ports). The other 48 ports (labeled 0 through 47) are SFP+ ports that support 25-Gigabit Ethernet interfaces, 10-Gigabit Ethernet interfaces, or 1-Gigabit Ethernet interfaces. The default speed for the SFP+ ports is 10 Gbps.

By default, the 100-Gigabit Ethernet and 40-Gigabit Ethernet interfaces appear in the et-fpc/pic/port format. When the 100-Gigabit Ethernet interfaces are channelized as 25-Gigabit Ethernet interfaces, the interface names appear in the et-fpc/pic/port:channel format. When the 40-Gigabit Ethernet interfaces are channelized as 10-Gigabit Ethernet interfaces, the interface names appear in the xe-fpc/pic/port:channel format, where channel can be a value of 0 through 3. Auto-channelization is enabled by default on the uplink ports. If you have disabled auto-channelization, then to channelize the ports, manually configure the port speed using the set chassis fpc slot-number port port-number channel-speed speed command, where the speed can be set to 10G or 25G. If a 100-Gigabit Ethernet transceiver is connected, you can only set the speed to 25G. For the SFP+ ports, you can set the speed to 25G or 1G. There is no commit check for this, however.

Note:

On QFX5120 switches, the uplink ports support auto-channelization.

Starting in Junos OS Release 19.4R1, you can use any of the following JNP-SFP-25G-DAC cables to set 10-Gbps speed on the SFP28 ports of a QFX5120-48Y switch:

  • JNP-SFP-25G-DAC-1M

  • JNP-SFP-25G-DAC-3M

  • JNP-SFP-25G-DAC-5M

If you've plugged a JNP-SFP-25G-DAC cable into a QFX5120-48Y switch, then the SFP28 ports come up with 10-Gbps speed by default. To configure the SFP28 ports to operate at 25-Gbps speed, you must explicitly configure the speed of the first port in the port group using the set chassis fpc 0 pic 0 port port-num speed 25g command.

QFX5120-48Y does not support autonegotiation when 1-gigabit fiber SFP transceiver is plugged in. In such cases, it is recommended to disable auto-negotiation on the remote end device. But, QFX5120-48Y switches with 1-gigabit copper SFP transceiver supports autonegotiation, as the physical layer within the transceiver handles autonegotiation.

The following steps describe how to channelize uplink ports (block of ports or individual ports).

  1. To configure a block of 100-Gigabit Ethernet (et) ports to operate as 25-Gigabit Ethernet ports, specify a port range and channel speed:

    For example, to configure ports 48 through 55 on PIC 0 to operate as 25-Gigabit Ethernet ports:

  2. To configure a block of 40-Gigabit Ethernet (et) ports to operate as 10-Gigabit Ethernet ports, specify a port range and channel speed:

    For example, to configure ports 48 through 55 on PIC 0 to operate as 10-Gigabit Ethernet ports:

  3. To configure an individual 100-Gigabit Ethernet (et) port to operate as 25-Gigabit Ethernet (xe) ports, specify a port number and channel speed:

    For example, to configure port 55 to operate as a 25-Gigabit Ethernet port:

  4. To configure an individual 40-Gigabit Ethernet (et) port to operate as 10-Gigabit Ethernet (xe) ports, specify a port number and channel speed:

    For example, to configure port 55 to operate as 10-Gigabit Ethernet ports:

  5. Review your configuration and issue the commit command.
  6. To return a range of ports from the 25-Gigabit Ethernet configuration to the default 100-Gigabit Ethernet configuration, delete the 25g statement:

    For example, to return ports 48 through 55 from the 25-Gigabit Ethernet configuration to the default 100-Gigabit Ethernet configuration:

    Note:

    To configure the ports to another channel-speed, you must delete the current port-range statement to return to the default 100-Gigabit Ethernet configuration.

  7. Review your configuration and issue the commit command.

The following steps describe how to channelize SFP/SFP28 block of ports. You can configure the SFP and SFP28 port speeds only per quad (group of 4 ports) and not individually. All ports operate at a single speed within the quad. For instance, if you configure ports 8 through 11 to operate as 25-Gigabit Ethernet ports and you insert a 10G SFP+ transceiver in port 10, an interface is not created for this port.

  1. To configure a block of four 10-Gigabit Ethernet (et) ports (quad ports) to operate as 25-Gigabit Ethernet ports, specify the speed for the first port of the quad ports. For instance,

    For example, to configure ports 4 through 7 to operate as 25-Gigabit Ethernet ports, you must configure port 4 to operate as 25-Gigabit Ethernet ports:

  2. Review your configuration and issue the commit command.

  3. To return a range of ports from the 25-Gigabit Ethernet configuration to the default 10-Gigabit Ethernet configuration, delete the 25g statement:

    For example, to return ports 4 through 7 from the 25-Gigabit Ethernet configuration to the default 10-Gigabit Ethernet configuration:

    Note:

    To configure the ports to another speed, you must delete the current port speed statement to return to the default 10-Gigabit Ethernet configuration.

  4. Review your configuration and issue the commit command.

Channelizing Interfaces on QFX5120-48YM Switches

For information on QFX5120-48YM Switches, see QFX5120 Switch Hardware Guide.

For information about platform support, see Hardware Compatibility Tool (HCT).

On the QFX5120-48YM switch, there a total of 56 (48 SFP28 ports and 8 QSFP28 ports) logical ports. Table 9 summarizes the speed and channelization support on QFX5120-48YM switches.

Supports both manual (using CLI) channelization and auto-channelization. However, the manual/CLI channelization always takes the higher precedence.

You can channelize a particular port, using the set chassis fpc 0 pic 0 port port-num channel-speed (10G|25G|50G) command.

The port-range CLI is not supported, which means, you cannot channelize block of ports. You can only channelize the individual ports.

All 40-Gigabit and 100-Gigabit Ethernet ports support auto channelization with the following limitations:

  • Port 50 and 52 can be channelized to 2x50G/4x25G/4x10G.

  • 10G/1G AN is not supported.

On the QFX5120-48YM switch, there are a total of 56 ports. Of these 56 ports, 8 ports (labeled 48 through 55) are uplink ports that support 100-Gigabit Ethernet interfaces (QSFP28 ports) and 40-Gigabit Ethernet interfaces (QSFP+ ports). The other 48 ports (labeled 0 through 47) are SFP+ ports that support 25-Gigabit Ethernet interfaces, 10-Gigabit Ethernet interfaces, or 1-Gigabit Ethernet interfaces. The default speed for the SFP+ ports is 10 Gbps.

The QSFP28 ports can be channelized to 2x50G/4x25G/4x10G. Channelization supports only on fixed two ports, such as Port 50 and Port 52. To channelize the ports (port 50 or port 52), manually configure the port speed using the set chassis fpc slot-number port port-number channel-speed speed command, where the speed can be set to 10G.

By default, the 100-Gbps QSFP+ or QSFP28 ports on QFX5120-48YM switch are channelized automatically if any of the four channels on a 100-Gbps QSFP+ port receive data, unless you have configured channelization either at the chassis level or at the port level. Auto-channelization does not support Virtual chassis ports.

To configure the SFP ports to 25G or 1G the set chassis fpc 0 pic 0 port <> speed <25g/1g> command must apply on the first port of the quad.

To channelize individual ports on QFX5120-48YM Switches, see Table 1.

On configuring port channelization, system reboot is not required.

See Interface Naming Conventions for channelized and non-channelized interface naming formats.

Table 10 describes the naming formats for the QSFP ports (50 and 52) can be channelized.

QFX5120-48YM does not support autonegotiation when 1-gigabit fiber SFP transceiver is plugged in. In such cases, it is recommended to disable auto-negotiation on the remote end device.

Channelizing Interfaces on QFX5120-48T Switches

For information about platform support, see Hardware Compatibility Tool (HCT).

On the QFX5120-48T switch, there a total of 54 ports. Table 12 summarizes the speed and channelization support on QFX5120-48T switches.

You can only configure speed per port on QFX5120-48T switches. We do not support port group configuration.

You can channelize a particular port, using the set chassis fpc 0 pic 0 port port-num channel-speed (10G|25G|50G) command.

The port-range CLI is not supported, which means, you cannot channelize block of ports. You can only channelize the individual ports.

All 40-Gigabit and 100-Gigabit Ethernet ports support auto channelization with the following limitations:

  • Port 50 and 51 supports either 4x10G or 4x25G based on the optic used.

  • All ports support 2x50G.

QFX5120-48T switches support 1-Gbps speed on ports 0 - 47. To configure 1-Gbps speed per port, use the set interface interface-name speed 1G command.

Channelizing Interfaces on QFX5700 Switches

The QFX5700 switches have QFX5K-FPC-20Y line card (20x10G/25G FPC), QFX5K-FPC-16C line card (16x100GE FPC) and QFX5K-FPC-4CD line card (4x400G FPC) with support of 20x25GE SFP28 ports, 16x100GE QSFP28 and 4x400GE QSFP56-DD ports.

For information on the line card, see QFX5K-FPC-20Y, QFX5K-FPC-4CD and QFX5K-FPC-16C for QFX5700 Switches.

For information about platform support, see Hardware Compatibility Tool (HCT).

For information on QFX5700 switches, see QFX5700 Switch Hardware Guide.

Speed Support on QFX5K-FPC-16C Line Card

The QFX5K-FPC-16C line card contains a total of 16 QSFP28 ports.

You can configure QFX5K-FPC-16C line card with 100-Gbps or 40-Gbps speeds.

You can channelize the QSP28 ports to four 25-Gigabit Ethernet or four 10-Gigabit Ethernet ports. By default, the line card comes up in 100-Gbps speed.

Follow these guidelines when you configure the channelization:

  • You can channelize ports (0,4,8,12) as four 10-Gigabit Ethernet interfaces, or four 25-Gigabit Ethernet interfaces. For example, et-5/0/0, et-5/0/4, et-5/0/8, and et-5/0/12 can be channelized into four 10-Gigabit Ethernet interfaces, or four 25-Gigabit Ethernet mode.
  • If you channelize a port, then the next three consecutive ports (1,2,3,5,6,7,9,10,11,13,14,15) cannot be used for any purpose. For example, if et-5/0/4 is channelized into four 25-Gigabit Ethernet mode, then et-5/0/5, et-5/0/6 and et-5/0/7 cannot be used for any purpose.

For example: If you want to channelize port 0 to 40-Gbps or 100-Gbps speed to four 25-Gigabit Ethernet or four 10-Gigabit Ethernet speed, then port 1, 2, and 3 must be set to unused.

Table 19 summarizes how the speed can be set on other ports while channelizing speeds in port 0 or 4 or 8 or 12.

In QFX5K-FPC-16C line card, you can commit the configurations in the following two ways:

  • You can configure the unused ports first and commit that configuration separately. After committing the unused port, you can configure the number-of-sub ports and commit the configuration again.
  • Or, you can configure both unused ports and number-of-sub ports together and commit the configuration once.

Example for channelization configuration

  1. Block the port following the next three consecutive ports 100-Gbps or 40-Gbps port as unused and commit the configuration.

  2. Configure the speed on the desired port (et-0/0/y) as 25-Gbps or 10-Gbps and commit the configuration.

Example to delete channelization configuration

To remove the channelization configuration from a set of QFX5K-FPC-16C line card ports, delete the configuration from the channelized port and commit the configuration. For example:

To enable port level speed configuration, use set interfaces <interface-name> speed <speed> number-of-sub-ports <sub-ports> statement.

To channelize individual ports on QFX5K-FPC-16C line card, see Table 1.

Table 20 summarizes the supported port speeds on QFX5K-FPC-16C Line Card.

All active ports operate in 100 Gigabit Ethernet mode.

When channelization is done in ports (0, 4, 8, and 12) then the next three consecutive non-channelized ports (1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 14, and 15) need to be configured as unused ports. To do the same refer to Example for channelization configuration to configure a port as unused.

In QFX5K-FPC-4CD line card, you can commit the configurations and unused port configuration is not required to channelize the ports.

Example for channelization configuration

  1. Configure the speed on the desired port (et-0/0/y) as 400-Gbps or 4x100-Gbps or 100-Gbps or 40-Gbps and commit the configuration.

Speed Support on QFX5K-FPC-20Y Line Card

The QFX5K-FPC-20Y line card contains a total of 20 (SFP+, SFP28, and SFP56) ports.

You can configure QFX5K-FPC-20Y line card with 10-Gbps, 25-Gbps, or 50-Gbps speeds.

Starting in Junos OS Evolved Release 22.2R1, we support 50-Gbps speed on QFX5K-FPC-20Y line card.

You can use all 20 ports when you insert the line card in 0, 2, 4, or 6 slots and interfaces for all 20 ports are created. When you insert the line card in slots 1, 3, 5, or 7, only first 16 interfaces are created. For example, if you insert the line card in slot 1, you can only use the first 16 ports. If you want to use all the 20 ports in the linecard, you must insert the linecard in 0, 2, 4, or 6 slots.

Zero Touch Provisioning (ZTP) with speeds of 10-Gbps, 25-Gbps, and 50-Gbps only for IPv4 is supported on JNP-FPC-20Y line card. Default speed is 25-Gbps.

Alarm and FEC Configuration on QFX5K-FPC-20Y, QFX5K-FPC-16C, and QFX5K-FPC-4CD Line Cards

An alarm is raised in the following cases:

  • Optics does not support configured speed: When there is a mismatch between the transceiver inserted into a port and the speed configured on the port.
  • Invalid port speed configuration: when you attempt to configure an invalid or unsupported speed for any port in the switch. In this case, the port falls back to the default speed.

Enabling FEC (Forward Error Correction) for an interface depends on the port speed, SERDES lane speed, and the optics type. By default, the Junos OS and Junos OS Evolved software enables the FEC for an interface based on these factors.

Table 25 summarizes the default FEC configuration for the various port speeds of QFX5K-FPC-20Y, QFX5K-FPC-16C, QFX5K-FPC-4CD line cards.

Total number of ports- 56; 48 SFP+ ports and eight uplink ports.

Auto speed detection mode (Enabled by default)

If you have disabled auto-channelization, then to channelize the ports, manually configure the port speed using the set chassis fpc slot-number port port-number channel-speed speed command, where the speed can be set to 10G or 25G. If a 100-Gigabit Ethernet transceiver is connected, you can only set the speed to 25G. For the SFP+ ports, you can set the speed to 25G or 1G. There is no commit check for this, however.

On EX4650 switches, the uplink ports support auto-channelization.

You can configure the SFP and SFP28 port speeds only per quad (group of 4 ports) and not individually. To configure speed for the quad, refer Table 1.

The interface will not get created automatically on inserting 1-Gigabit Ethernet or 25-Gigabit Ethernet transceivers. You must use the CLI to configure the port speed to 1-Gigabit Ethernet or 25-Gigabit Ethernet mode manually​.​

EX4650-48Y does not support autonegotiation when 1-gigabit fiber SFP transceiver is plugged in. In such cases, it is recommended to disable auto-negotiation on the remote end device. But, EX4650-48Y switches with 1-gigabit copper SFP transceiver supports autonegotiation, as the physical layer within the transceiver handles autonegotiation.

Note:
  • When the two 100 GbE QSFP28 ports of PIC 1 of EX4400 switches are configured to operate as network ports, they support channelization.

  • You can channelize the 100G/40G ports to 4x25G and 4x10G using CLI configuration for both PIC 1 and PIC 2. See Port Settings to configure channelization.

  • You can configure one port at 100 Gbps and the other at 40 Gbps at the same time, if needed.

  • By default, each of the two QSFP28 ports in PIC1 of EX4400 (except EX4400-24X) is configured as two logical 50-Gbps VCP interfaces.

Use the request virtual-chassis mode network-port command to convert 1x100 GbE VCPs to network mode and reboot the system. Use the request virtual-chassis mode network-port disable command to disable network-port mode and reboot the system.

The maximum MTU size supported on EX4100 switches is 9216 bytes. Packets above MTU+8 bytes are marked as oversized frames and those between MTU+4 and MTU+8 bytes with invalid errors.

Virtual Chassis Ports and Network Ports

You can use the request virtual-chassis mode network-port command to enable network port mode, which converts the default VCPs on the switch into network ports. After executing this command, you must reboot the switch for this command to take effect.

To disable network port mode and return these ports to their default settings as VCPs, use the network-port and disable options with the request virtual-chassis mode command. You must reboot the switch for network port mode changes to take effect, so you can include the reboot option in the same command. For example:

request virtual-chassis mode network-port disable reboot

The following are some of the guidelines for configuring the VCPs:

  • In the EX4100 switches family, all four dedicated ports on PIC 1 are VCPs by default. You can convert the VCPs to network ports. The ports work either as VCPs or network ports, where mixed mode is not supported. On conversion of VC ports to network ports, all the ports dynamically detect the port speed.
  • The default speed of VCPs in EX4100-48P, EX4100-48T, EX4100-24P, EX4100-24T, EX4100-24MP, and EX4100-48MP switches is 4x25G. You can convert the VCPs of these switches to network ports that operates at the speed of 25G, 10G, and 1G. You can configure the network ports in mixed speed. For example, port 0 with 1x25G, port 1 with 1x10G, and ports 2 and 3 with 2x1G.
  • The default speed of VCPs in EX4100-F-48P, EX4100-F-48T, EX4100-F-24P, EX4100-F-24T, EX4100-F-12P, and EX4100-F-12T switches is 4x10G. You can convert the VCPs of EX4100-F-48P, EX4100-F-48T, EX4100-F-24P, EX4100-F-24T, EX4100-F-12P, and EX4100-F-12T switches to network ports that operates at the speed of 4x10G or 4x1G. The ports work either as VCPs or network ports, where mixed mode is not supported. But you can configure the network ports in mixed speed. For example, port 0 with 1x10G, port 2 with 1x10G, and ports 2 and 3 with 2x1G.
  • In the EX4100 switches family, we support 1G speed on PIC1 in network mode only and not as a virtual chassis port.

Channelization

Follow the guidelines below to channelize port speeds:

QSFP-DD:

  • To channelize QSFP-DD port into 8x50G, mark five SFP-DD ports as unused.

    Example: To channelize et-0/0/48, mark et-0/0/0 to et-0/0/4 as unused.

  • To channelize QSFP-DD port into 4x100G, 4x25G, or 4x10G, mark one SFP-DD port as unused.

    Example:

    • To channelize et-0/0/49, mark et-0/0/5 as unused.

    • To channelize et-0/0/52, mark et-0/024 as unused.

  • To channelize QSFP-DD port into 2x200G, do not mark any port as unused.

Understanding Port Ranges and System Modes

QFX Series devices and EX4600 switches can support different port ranges depending on the device, media type of the interface, the software that is running on the device, and the system mode.

This topic describes:

Port Ranges for Different Media Types

The following media types support the following port ranges:

  • On a QFX3500 device:

    • The valid port range for a Fibre Channel (fc) interface is 0 through 5 and 42 through 47 on PIC 0, with a total of 12 available Fibre Channel ports.

      Note:

      Fibre Channel ports are not supported on QFX3500, QFX3600, and QFX5100 switches running Enhanced Layer 2 software.

    • The valid port range for a Gigabit Ethernet (ge) interface is 6 through 41 on PIC 0 because the ports between 0 and 5 and 42 and 47 are reserved as Fibre Channel ports. The total number of available Gigabit Ethernet ports is 36, because 12 of the remaining 48 ports are reserved for Fibre Channel and 10-Gigabit Ethernet interfaces. Fibre Channel ports cannot be configured as Gigabit Ethernet ports.

    • The valid port range for a 10-Gigabit Ethernet (xe) interface is 0 through 47 on PIC 0. The valid port range for a 10-Gigabit Ethernet (xe) interface is 0 through 15 on PIC 1. The total number of available 10-Gigabit Ethernet ports is 64.

    • The valid port range for a 40-Gigabit data plane uplink interface is 0 through 3 on PIC 1

    • The valid port range for a 40-Gigabit Ethernet interface is 0 through 3 on PIC 2. There are four available ports.

  • On a QFX3600 Node device:

    • The valid port range for a 10-Gigabit Ethernet interface is 8 through 63 on PIC 0. There are 56 available ports.

    • The valid port range for a 40-Gigabit Ethernet interface is 2 through 15 on PIC 1. There are 14 available ports.

    • The valid port range for a 40-Gigabit data plane uplink interface is 0 through 7 on PIC 1. There are eight available ports.

    See Table 53 for physical port to logical port mappings.

  • On a QFX3600 switch running Enhanced Layer 2 Software:

    • The valid port range for a 10-Gigabit Ethernet interface is 0 through 63 on PIC 0. There are 64 available ports.

    • The valid port range for a 40-Gigabit Ethernet interface is 0 through 15 on PIC 0. There are 16 available ports.

    See Table 54 for physical port to logical port mappings.

  • On QFX5100-48S and QFX5100-48T switches running Enhanced Layer 2 Software:

    • The valid port range for a 10-Gigabit Ethernet interface is 0 through 47 on PIC 0. There are 48 available ports. When you channelize the 6 40-Gbps QSFP+ ports on 0 through 5 on PIC 1, there are 72 available ports.

      Note:

      On PIC 1, ports 0 and 1 are reserved for fte ports. You cannot convert these fte ports to xe or xle ports.

    • The valid port range for a 40-Gbps QSFP+ port is 0 through 5 on PIC 1. There are six available ports.

    See Table 56 for physical port to logical port mappings.

  • On EX4600 switches running Enhanced Layer 2 Software:

    • The valid port range for a 10-Gigabit Ethernet interface is 0 through 23 on PIC 0. There are 24 available ports. When you channelize the 4 40-Gbps QSFP+ ports on 24 through 27 on PIC 0. There are 40 available ports.

    See Table 56 for physical port to logical port mappings.

  • On QFX5100-48S and QFX5100-48T switches running a QFabric software package:

    • The valid port range for a 10-Gigabit Ethernet interface is 0 through 47 on PIC 0. There are 48 available ports.

    • The valid port range for a 40-Gbps QSFP+ port is 0 through 5 on PIC 1. There are six available ports.

      Note:

      On PIC 1, ports 0 and 1 are reserved for fte ports. You cannot convert these fte ports to xe or xle ports.

    See Table 57 for physical port to logical port mappings.

  • For QFX5100-24Q and QFX5100-96S switches running Enhanced Layer 2 Software, see Table 58 for physical port to logical port mappings for different system modes.

Supported System Modes

Note:

There are restrictions on the ports you can channelize on the QFX5100-24Q and QFX5100-96S switches depending on the system mode you configure. If you try to channelize ports that are restricted, the configuration is ignored.

The following system modes are available on the QFX5100-24Q switch:

  • Default mode

  • Mode-104-port

  • Flexi-PIC mode

  • Non-oversubscribed mode

See Table 58 for more information regarding the supported system modes for your switch.

The following system modes are available on the QFX5100-96S switch:

  • Default-mode

  • Non-oversubscribed mode

QFX5100-24Q

Supported

You do not need to configure the switch to be in this mode. On PIC 0, you can channelize all 24 40-Gbps QSFP+ ports. On PIC 1 and PIC 2, the 40-Gbps QSFP+ ports in the expansion modules are supported but cannot be channelized. In this mode, you can have one of two port combinations: 32 40-Gbps QSFP+ ports, or 96 10-Gigabit Ethernet ports plus 8 40-Gbps QSFP+ ports.

Supported

On PIC 0, all 24 40-Gbps QSFP+ ports are channelized by default, which provides 96 10-Gigabit Ethernet ports. 40-Gbps QSFP+ ports contained in an expansion module on PIC 1 are supported. On PIC 1, ports 0 and 2 are channelized by default, and ports 1 and 3 are disabled. If 40-Gbps QSFP+ ports contained in an expansion module are detected on PIC 2, they are ignored.

Supported

On PIC 0, the first four ports (ports 0 through 3) cannot be channelized. 40-Gbps QSFP+ ports contained in expansion modules on PIC 1 and PIC 2 are supported but cannot be channelized.

Supported

All 24 40-Gbps QSFP+ ports on PIC 0 can be channelized to 96 10-Gigabit Ethernet ports. 40-Gbps QSFP+ ports contained in the expansion modules on PIC 1 and PIC 2 are not supported and cannot be channelized. There is no packet loss for packets of any size in this mode.

QFX5100-96S

Supported

You do not need to configure the switch to be in this mode. On PIC 0, all 96 10-Gigabit Ethernet ports are supported. You can only channelize the 40-GbpsQSFP+ interfaces to 10-Gibabit Ethernet interfaces on ports 96 and 100. When you channelize the interfaces on ports 96 and 100, ports 97, 98, 99, 101, 102 and 103 are disabled.

Not supported

Not supported

Supported

On PIC 0, all 96 10-Gigabit Ethernet ports are supported. However, the eight 40-Gbps QSFP+ ports are not supported and cannot be channelized. There is no packet loss for packets of any size in this mode.

Configuring the System Mode

You can configure different system modes to achieve varying levels of port density on the QFX5100-24Q, QFX5100-96S, and QFX5110-32Q switches. Depending on the system mode you configure, there are restrictions on which ports you can channelize. If you channelize ports that are restricted, the configuration is ignored. By default, all QSFP+ interfaces are auto-channelized. Auto-channelization is not supported on interfaces contained in expansion modules or on Virtual Chassis ports. To disable auto-channelization, see Channelizing Interfaces on QFX3500, QFX3600, QFX5100, QFX10002, QFX10008, QFX10016, and EX4600 Switches for more information.

Note:

QFX5200 switches do not support System Mode.

Note:

When you request the system mode change, we recommend that you reboot the switch for the system mode to take effect.

CAUTION:

The Packet Forwarding Engine on the switch is restarted when you issue system mode changes. As a result, you might experience packet loss on the switch.

See Table 59, Table 60, Table 61, and Table 62 for more information regarding the supported system modes for your switch.

All 32 QSFP+ ports on the switch are configured for 40-Gigabit Ethernet only. All ports are supported as access or uplink ports, but cannot be channelized.

Not supported

Supported

  • Ports 0 through 19 of the switch are configured for 40-Gigabit Ethernet and can be channelized to 4 independent 10-Gigabit Ethernet ports.

  • Ports 20 though 27 are disabled.

  • Ports 28 through 31 are configured as 100-Gigabit Ethernet.

Supported

See QFX5110-32Q Port Panel for more details.

CAUTION:

Changing the system mode causes the FPC to reboot. Because there can be a slight loss of data while the FPC reboots, we recommend that you only configure the changes during a maintenance window for this release.

CAUTION:

Take care when changing the channelization mode from Flexi-pic to default. If you have existing ports that are channelized in Flexi-pic mode, remove the channelization from the interface before changing the system mode. Changing the Flexi-pic mode to the default mode with channelized ports causes the ports to go down, log a system log error, and remain down. You must manually remove the channelization configuration on the ports to bring the ports up in default mode.

The following steps describe how to change the system mode.

  1. To change the system mode, issue the following operational command:

    For example:

  2. To return to the default mode (default-mode), issue the following operational command:
  3. To see which system mode is configured, issue the following operational command:

Configuring the Port Type on QFX3600 Standalone Switches

The QFX3600 standalone switch provides 16 40-Gbps QSFP+ ports. By default, all 16 ports operate as 40-Gigabit Ethernet (xle) ports. Optionally, you can choose to configure the 40-Gbps ports to operate as four 10-Gigabit Ethernet (xe) ports. You can use QSFP+ to four SFP+ breakout cables or QSFP+ transceivers with fiber breakout cables to connect the 10-Gigabit Ethernet ports to other servers, storage, and switches. You can configure up to 64 10-Gigabit Ethernet ports on ports Q0 through Q15.

This topic explains how to configure the port type on QFX3600 standalone switches.

CAUTION:

The Packet Forwarding Engine on the QFX3600 standalone switch is restarted when you commit the port type configuration changes. As a result, you might experience packet loss on the switch.

The following message may be displayed in the system log file when the Packet Forwarding Engine is restarted. You can ignore this message.

Pipe write error: Broken pipe

flush operation failed

The following steps describe how to configure either a block of ports or an individual port to operate as 10-Gigabit Ethernet (xe) ports, as well as how to delete a 10-Gigabit Ethernet (xe) port configuration.

Note:

When you delete the xe port type configuration for an individual port or a block of ports, the ports return to operating as 40-Gigabit Ethernet (xle) ports.

  1. To configure a block of ports to operate as 10-Gigabit Ethernet (xe) ports, specify a port range:

    For example, to configure ports Q4 through Q7 to operate as 10-Gigabit Ethernet ports:

  2. To configure an individual port to operate as a 10-Gigabit Ethernet (xe) port, specify a port number:

    For example, to configure port Q4 to operate as a 10-Gigabit Ethernet port:

  3. Review your configuration and issue the commit command.
  4. To delete the 10-Gigabit Ethernet (xe) port configuration for a block of ports (and return to the default 40-Gigabit Ethernet configuration), specify a port range:

    For example, to delete the 10-Gigabit Ethernet port configuration for ports Q4 through Q7:

  5. To delete the 10-Gigabit Ethernet (xe) port configuration for an individual port (and return to the default 40-Gigabit Ethernet configuration), specify a port number:

    For example, to delete the 10-Gigabit Ethernet port configuration for port Q4:

Configuring the QSFP+ Port Type on QFX3500 Standalone Switches

By default, the four 40-Gbps QSFP+ ports are configured to operate as 10-Gigabit Ethernet (xe) ports. You can use QSFP+ to four SFP+ breakout cables or QSFP+ transceivers with fiber breakout cables to connect the 10-Gigabit Ethernet ports to other servers, storage, and switches. You can, however, configure the four 40-Gbps QSFP+ ports to operate as 40-Gigabit Ethernet (xle) ports.

Note:

Port Q0 supports only three (not the typical four) 10-Gigabit Ethernet ports, because one port is reserved.

CAUTION:

The Packet Forwarding Engine on the QFX3500 standalone switch is restarted when you commit port type configuration changes (for example, configuring or deleting an xle port). As a result, you might experience packet loss on the device.

The following steps describe how to configure either a block of ports or an individual port to operate as 40-Gigabit Ethernet (xle) ports, as well as how to delete a 40-Gigabit Ethernet (xle) configuration.

Note:

When you delete an xle block of ports or individual port, the ports return to operating as 10-Gigabit Ethernet ports.

  1. To configure a block of ports to operate as 40-Gigabit Ethernet (xle) ports, specify a port range:

    For example, to configure ports Q0 through Q3 to operate as 40-Gigabit Ethernet ports:

  2. To configure an individual port to operate as a 40-Gigabit Ethernet (xle) port, specify a port number:

    For example, to configure port Q2 to operate as a 40-Gigabit Ethernet port:

  3. Review your configuration and issue the commit command.
  4. To delete a block of ports configured as 40-Gigabit Ethernet (xle) ports (and return to the default 10-Gigabit Ethernet configuration), specify a port range:

    For example, to delete the 40-Gigabit Ethernet (xle) port configuration for ports Q0 through Q3 (and return to the default 10-Gigabit Ethernet configuration):

  5. To delete an individual port configured as a 40-Gigabit Ethernet (xle) port (and return to the default 10-Gigabit Ethernet configuration), specify an individual port:

    For example, to delete the 40-Gigabit Ethernet (xle) port configuration for port Q2 (and return to the default 10-Gigabit Ethernet configuration):

  6. Review your configuration and issue the commit command.

Configuring the QSFP+ Port Type on QFX5100 Devices

You can convert default 40-Gigabit Ethernet data plane uplink interfaces (fte) to 40-Gigabit Ethernet access interfaces (xle) ports, and default 40-Gigabit Ethernet interfaces (xle) to 40-Gigabit Ethernet data plane uplink interfaces (fte). Ports Q0 and Q1 are fixed fte ports and cannot be changed. Ports Q2 and Q3 are fte ports by default but can be changed to xle ports. Ports Q4 and Q5 are xle ports by default but can be changed to fte ports.

Note:

On QFX5100-24Q switches, ports Q1 through Q7 are fixed FTE ports and cannot be changed.

Note:

You must configure xle ports in pairs, not individually, otherwise functionality is not guaranteed.

CAUTION:

The Packet Forwarding Engine on a QFX5100 switch is restarted when you commit port type configuration changes (for example, configuring or deleting an fte or xle port). As a result, you might experience packet loss on the device.

The following steps describe how to configure either a block of ports or an individual port, as well as how to delete these configurations.
