Port Speed on PTX Routers
In this topic we have information related to the port speed on a PTX routers and line cards, support for multiple port speed details, guidelines and how to configure the port speed.
Port Speed on PTX10K-LC1201
PTX10008 routers support 8 PTX10K-LC1201 line cards. Starting in Junos OS Evolved
Release 20.1R2 and 20.2R1, we now support a new port profile configuration to
configure port speeds on the PTX10K-LC1201 line card. You can configure the port
speed on the PTX10K-LC1201 line card by using the port profile configuration
commands in the [edit interfaces] hierarchy. To streamline the
configuration, the new port profile configuration commands are migrated from the
[edit chassis] hierarchy to the [edit
interfaces] hierarchy for the PTX10K-LC1201 line card.
Starting in Junos OS Evolved Release 20.4R1, you can configure 10Gbps speed and
select the wavelength with SFP+ optics by plugging in the QSA adapter on the
QSFP/QSFP+ ports of PTX10K-LC1201 line card. You can now configure the 10Gbps speed
by using the set interfaces
et-<fpc>/<pic>/<port> speed
<10g> or set interfaces
et-<fpc>/<pic>/<port> speed <10g>
number-of-sub-ports (1) commands. You can select the wavelength of the
SFP+ ports by using the set interfaces
et-<fpc>/<pic>/<port>:channel number
optics-options wavelength wavelength command and
view the output using the show interfaces diagnostics optics
name command.
For information on the line card, see PTX10K-LC1201-36D for PTX10008 Routers.
To view the supported transceivers, optical interfaces, and DAC cables on PTX10K-LC1201, see Hardware Compatibility Tool (HCT).
Table 1 summarizes the line card details and their description.

Port Speed Configuration |
|
When you change the speed of the port, or change the
number-of-sub-ports per port, or configure or remove the
number-of-sub-ports, the interfaces will be deleted and re-created for that
port.

You can configure the active physical ports in a PIC. By default, all the physical
ports in an interface are active. Use the unused command to control
the number of interfaces created on a physical port in a PIC. If you configure a
port as unused, no interfaces (channelized or non-channelized) are
created for that port.
On channelized interfaces, the prefix et- is used irrespective
of the speed you configure. All channelized interfaces have the same speed. You
cannot configure an individual speed for each channelized interface. You can
configure the number of channelized interfaces by using the
number-of-sub-ports command. On non-channelized interfaces, the
prefix et- is used irrespective of the speed configured. If
you do not configure the speed, by using the optional speed command, default speed
is assigned to the interface.

MTU size |
PTX10001-36MR router WAN interfaces support maximum MTU of size 16000 bytes for transit traffic. However for the traffic that is destined to host or is originating from host (such as protocol traffic), the maximum MTU limit is 9500 bytes. If any of the host bound packets or host originating packet is above 9500 bytes, then the packet will be dropped. Hence, if you are expecting host packets greater than 9500 bytes, then the WAN interface MTU value must be set as value less than or equal to 9500 bytes. |

You can channelize to: |
|---|---|
|
400-Gigabit Ethernet capable ports |
|
|
100-Gigabit Ethernet capable ports |
You can configure all four 100-Gigabit Ethernet capable ports (ports 4, 5, 6, and 7) to operate at 100-Gbps speeds. Note that, you can configure port 4 and port 6 to operate at 1x100-Gbps, 4x10-Gbps, 4x25-Gbps, or 1x40-Gbps speeds with the following conditions:
|
Starting in Junos OS Evolved Release 20.3R1, you can configure the port speed on the
PTX10001-36MR router by using the port profile configuration commands in the
[edit interfaces] hierarchy. To streamline the configuration,
the port profile configuration commands are migrated from the [edit
chassis] hierarchy to the [edit interfaces] hierarchy
for the PTX10001-36MR router.
From Junos OS Evolved Release
21.2R1, we support autonegotiation and linktraining using 400G DAC cable for
PTX10001-36MR. This is not a default behavior. Use auto-negotiation
under [edit interfaces interface-name ether-options] hierarchy
level to enable autonegotiation and link training. Enabling autonegotiation
automatically enables link training. This advertises configured speed on the
interface hierarchy. It does not upgrade or downgrade speed based on peers
advertised capability.
Autonegotiation and link training is supported only on the following channelization:
- One 400-Gigabit Ethernet interfaces (1x400G)
- Two 200-Gigabit Ethernet interfaces (2x200G)
- Four 100-Gigabit Ethernet interfaces (4x100G)
Configure speed at Port Level
To configure the PTX10001-36MR router at port level, follow the configuration steps in Configure Port Speed - Port Level in 20.2 releases. See speed for more details.
From Junos OS Evolved Release 20.3R1 you must use, set interfaces
et-<fpc>/<pic>/<port> speed <10g |
25g | 50g | 40g | 100g | 200g | 400g>, or set interfaces
et-<fpc>/<pic>/<port> speed <10g |
25g | 50g | 40g | 100g | 200g | 400g> number-of-sub-ports
(1|2|4|8) commands to configure the speed on the
ports.
You can configure port profiles in the command line interface without the physical presence of an FPC. If an invalid port profile configuration is detected while booting a FPC, an alarm is generated. Also, the default port profile is selected for that PIC.
If the port profile configuration is changed while the FPC is up and running, and the new configuration is invalid, an alarm is generated. The existing port profile configured continues to be used for that PIC.
You can configure any supported speed on 400-Gbps capable ports. Configuring speed on one of the 400-Gbps capable port will not disrupt the traffic on any other ports.
But, for 100-Gbps capable ports only speeds of 100-Gbps, 25-Gbps, 40-Gbps, and 10-Gbps are valid.
From Junos OS Evolved Release 20.3R1 you must use, the following command:
set interfaces et-<fpc>/<pic>/<port>
unused
If you configure request security system-keystore unlink command for a physical port in a PIC, then no channelized and non-channelized interfaces will be created. See request security system-keystore unlink for more information.
The Table 9 specifies which ports must be marked unused. If this rule is violated, then an alarm indicating port speed configuration error is raised. In such case, the existing running configuration will continue to be applied on such ports.
If the router reboots with such an invalid configuration, then the port with 40-Gbps, 4x10-Gbps, or 4x25-Gbps speed configuration and its counterpart port will not have any interfaces created for them.
Table 7 provides you the ports that you must power-off while configuring different speeds.

You can configure a port with more than one type of channelization mode for a given speed. For example, you can channelize a port to 1x100-Gbps, 2x100-Gbps, or 4x100-Gbps to configure the port to operate in 100-Gbps speed.
From Junos OS Evolved Release 20.3R1 to specify which of these channelization
modes on the ports, you must execute the following command at the [edit
interfaces] hierarchy:
set interfaces et-<fpc>/<pic>/<port>
speed <10g | 25g | 50g | 40g | 100g | 200g | 400g>
number-of-sub-ports (1|2|4|8)
See number-of-sub-ports (interface) for information on how to operate at different channelized speed.
When the number-of-sub-ports are not specified, the number of
channels are created as per Table 8:

- The router has a fabric capacity of 9.6 Tbps. When the router operates in 24 400 Gigabit Ethernet mode, the fabric does not experience an oversubscription. The oversubscription occurs when the router is configured in 24 400-Gigabit Ethernet and 12 100-Gigabit Ethernet modes. To avoid oversubscription of a PIC, the sum of the total speed configured on ports 4 to 11 within the PIC must be less than 1.6 Tbps.

Port Speed on PTX10K-LC1202-36MR
PTX10K-LC1202-36MR is a new fixed-configuration line card with 36 built-in ports which you can install in PTX10008 routers. On the PTX10K-LC1202-36MR, you can choose to configure the line card:
-
To operate at 3.6T mode, configure all the 36 ports to 100-Gbps speed, or
-
To operate at 4.8T mode, configure the four 400 GE ports (4, 10, 24, and 30) to operate at 400-Gbps speed and the remaining ports to operate at 100-Gbps speed.
For information on the line card, see PTX10008 Line Card Components and Descriptions.
To view the supported transceivers, optical interfaces, and DAC cables on PTX10K-LC1202-36MR, see Hardware Compatibility Tool (HCT).

Configure Port Speed for Non-Channelized Interfaces and Configure Port Speed for Channelized Interfaces describes the steps to configure the port speed for channelized and
non-channelized interfaces from the [edit interfaces]
hierarchy.
To configure ports at different speed, use the set interfaces
et-<fpc>/<pic>/<port> speed <10g |
25g | 40g | 100g | 400g> number-of-sub-ports <1|2|4|8>
command.
For the steps to configure the port speed from the [edit interfaces]
hierarchy. See speed for more details.
To channelize an interface, use the number-of-sub-ports command. The
number-of-sub-ports specifies the number of channelized
interfaces that you can configure on a physical port with the specified speed. Each
channel operates at the specified speed. The default value of
number-of-sub-ports per optics is 1. See number-of-sub-ports.
When the number-of-sub-ports are not specified, the number of
channels are created as per Table 11:

You can configure channelization on port 0 to port 3 and port 18 to port 21 with the following guidelines:
-
The 1x10-Gigabit Ethernet, 4x10-Gigabit Ethernet or 1x40-Gigabit Ethernet and 4x25-Gigabit Ethernet channelization is supported only on even numbered ports (that is, 0, 2, 18, 20).
-
When the even port x is channelized, you must set the odd port x+1 as unused. You must explicitly configure the ports that must be set as unused, using the following command:
set interface et-<fpc>/<pic>/<port> unused -
You cannot configure 1x10-Gigabit Ethernet, 4x10-Gigabit Ethernet or 1x40-Gigabit Ethernet and 4x25-Gigabit Ethernet simultaneously on the following ports:
-
port 0 and 2
-
port 18 and 20
-
You can configure port profiles in the command line interface without the physical presence of an FPC. If an invalid port profile configuration is detected while booting a FPC, an alarm is generated. Also, the default port profile is selected for that PIC.
If the port profile configuration is changed while the FPC is up and running, and the new configuration is invalid, an alarm is generated. The existing port profile configured continues to be used for that PIC.
To configure FEC mode, see fec (gigether).
You can configure every interface to loopback mode, see loopback.
Table 12 lists the naming conventions used for interfaces on PTX10K-LC1202-36MR (for 100-Gbps, 2x100-Gbps, 400-Gpbs, and 4x100-Gbps speeds) for PTX10008 routers. PTX10008 routers support eight PTX10K-LC1202-36MR line cards.

Port Speed on PTX10002-36QDD
Starting in Junos OS Evolved Release 24.2R2, PTX10002-36QDD supports multiple port
speeds and various channels under each port. In low power mode, the maximum port
speed is 400 Gbps, and the 800 Gbps port speed is supported in the standard power
mode. If a port speed is configured (or a port speed is determined by default)
without configuring number-of-sub-ports, the port will operate in a
non-channelized mode.
To view the supported transceivers, optical interfaces, and DAC cables on PTX10002-36QDD, see Hardware Compatibility Tool (HCT).

When port speed and sub-port-number are not configured for a port,
the PTX10002-36QDD are in non-channelized mode, with the default speed of
400-Gigabit Ethernet for both low-power and normal-power mode units
When you configure unused, the relevant port is disabled without
creating an interface.

Port Speed on PTX10003
Starting in Junos OS Evolved Release 19.3R1, you can configure 400-gigabit ethernet interfaces using QSFP56-DD-400GBASE-LR8 optics on PTX10003 routers. Only ports 0, 4, 5, 9 within each logical PIC support 400-Gigabit ethernet mode. When using 400G on port 0, the total bandwidth (speed x number-of-subports) of port 1 has to be less than 100G and port 2 has to be configured as 'unused' (see request security system-keystore unlink for more details). When using port 4 as 400G, port 3 must be configured with total bandwidth of less than 100G and port 2 must be configured 'unused'. Similarly, with port 5, 9 using 400G, port 6, 8 respectively must be configured for less than 100G and port 7 should be configured as 'unused'. That is, when a port is configured in 400-Gigabit ethernet mode, you cannot configure speed of the adjacent port to be more then 100-Gbps, and the middle port (2 between 0~4 or 7 between 5~9) must be set to unused. For example, you can set et-0/0/0 to 400G, et-0/0/1 to 100G or less, but et-0/0/2 must be set to unused.
For information on the PTX10003 router, see PTX10003-80C and PTX10003-160C Fixed Packet Transport Router Hardware Guide.
To view the supported transceivers, optical interfaces, and DAC cables on PTX10003, see Hardware Compatibility Tool (HCT).
Table 16 summarizes the Packet Forwarding Engine mapping and the supported port speeds for PTX10003-80C.

When port speed and sub-port-number are configured, the configured
values override the default port speed for the transceiver. If you try to configure
a port speed that is not supported by the transceiver, the port will be disabled. If
the port speed is not configured on a valid optical port, the PTX10003 router uses a
default port speed of 2x100 Gbps. If the number-of-subports is not
configured, 1x 40G | 100G |200G |400G data rate is assumed. 1x10G sub-port is not
supported.

The center port in each port group (port 2 and port 7) do not support 1x200 Gbps. To configure the speed as 200 Gbps for those ports, you'll need to configure them as 2x100 Gbps. For more details, see Understanding QSFP-DD Interfaces and Configurations . Also, only ports 0, 4, 5, or 9 on each PIC can support 400 Gbps or 4x100 Gbps. To configure the speed, you must plug in the appropriate transceiver and configure the speed.

To configure the number of optical channels for a particular port if the optics are
used in a channelized mode. You can use this configuration option to configure a
speed (10, 40, and 100 Gbps) in different number of channels based on the optics
used. The default value of number-of-sub-ports per optics is 1.
Following are the configurable values for the corresponding optic types:
