Port Panel of a QFX5100-24Q Device

The port panel of the QFX5100-24Q device consists of 24 quad small-form factor pluggable plus (QSFP+) ports. Each QSFP+ socket can be configured to support 40 GbE or as a set of 4 independent 10 GbE ports using breakout cables (channelization mode). In standalone mode, any of the 24 ports 0 through 23 can be configured as either uplink or access ports. The QFX5100-24Q device has two module bays for the optional expansion modules, QFX-EM-4Q or EX4600-EM-8F. The QFX-EM-4Q, can add a total of 8 additional QSFP+ ports to the chassis and the EX4600-EM-8F can provide 8 additional 10-Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) ports. The QFX-EM-4Q ports can also be configured as either access ports or as uplinks, but only ports 0 and 2 can be channelized using port mode. Figure 1 shows the port panel of the QFX5100-24Q device.

Switch Ports

The QFX5100-24Q device ports, (0 through 23) support:

  • 40 Gbps QSFP+ transceivers

  • QSFP+ to QSFP+ direct attach copper (DAC) cables

  • QSFP+ to SFP+ direct attach copper break out (DACBO) cables

  • QSFP+ to QSFP+ active optical cables (AOC)

  • QSFP+ to SFP+ active optical breakout cable (AOCBO)

  • Access ports

    You can use 40-Gigabit Ethernet QSFP+ transceivers and QSFP+ direct attach copper cables in any downstream port. See Determining Interface Support for the QFX5100 Device.

  • Uplink ports

    You can configure up to 4 of the 40 GbE ports as uplinks. Each additional QFX-EM-4Q, Expansion Module adds the switch uplink capacity by 2 for a total of 8 uplinks.

    To connect a QFX5100-24Q switch as a Node device in a QFabric system, you need:

    • Four QSFP+ uplink ports on each QFX5100-24Q Node device to connect to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect devices.

    • Two additional QSFP+ uplink ports on each QFX5100-24Q Node device connect to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect devices. .

QFabric Systems

The QFX5100-24Q operates as a Node device in both the QFX3000-G and QFX3000-M QFabric systems. Additionally, the QFX5100-24Q can be configured as an Interconnect Device in QFX3000-M QFabric systems allowing a maximum of 16 Node devices. The QFX5100-24Q may not be mixed with QFX3600-I Interconnect devices in the same QFabric system.

When operating as a Node device, ports 0 through 7 are default FTE ports; ports 8 through 15 can be configured as either uplink (FTE) or access ports (XLE). In the port range 8 through 23, only 12 ports can be channelized when the 2 QFX-EM-4Q are installed.

Note

The EX4600-EM-8S expansion module is not supported on the QFX5100-24Q device in a QFabric system.

Channelizing Interfaces (Non-QFabric)

When fully populated with 2 QFX-EM-4Q Expansion Modules, the QFX5100-24Q device has 128 physical ports. However, only 104 logical ports can be used for port channelization. Depending on the system mode you configure for channelization, different ports are restricted. If you attempt to channelize a restricted port, the configuration is ignored. The following system modes are available on the QFX5100-24Q device:

  • Default mode

    All 24 QSFP+ ports on the switch (PIC 0) are channelized by default (96 ports). With QFX-EM-4Q Expansion Modules (PIC 1) and (PIC 2), the QSFP+ ports are supported for access or uplink ports, but cannot be channelized. Ports are over-subscribed In this mode and could be subject to packet-loss. 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.

  • 104 port mode

    All 24 QSFP+ ports on the switch (PIC 0) are channelized (96 ports). Two ports on QFX-EM-4Q Expansion Module (PIC 1) are also channelized (8 additional). In this mode, ports 0 and 2 are channelized by default and ports 1 and 3 are disabled. If additional QSFP+ ports are detected in an expansion module (PIC 2), those ports are ignored.

  • Flexi-pic mode

    Ports 0 through 3 of the switch cannot be channelized; ports 4 through 24 are channelized by default (80 ports). With QFX-EM-4Q Expansion Modules (PIC 1) and (PIC 2), the QSFP+ ports are supported for access or uplink ports, but cannot be channelized. With EX4600-EM-8F Expansion Modules installed (PIC 1) and (PIC 2), the 16 SFP+ ports of SFP are recognized for a total of 96 logical ports.

  • Non-oversubscribed mode

    All 24 QSFP+ ports on the switch (PIC 0) are channelized (96 ports). 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.

Virtual Chassis and Virtual Chassis Fabric

The QFX5100-24Q device operates as a standalone switch, a member of a QFX Virtual Chassis, or as a spine or leaf device in a QFX5100 Virtual Chassis Fabric (VCF). QFX Virtual Chassis support up to 10 members. QFX5100 VCF supports 20 QFX5100 and EX4300 devices, of which 4 QFX5100 devices can be configured as spines.

To connect a QFX5100-24Q device as a member in a QFX Virtual Chassis, you need to cable a pair of ports to link each member in the Virtual Chassis into a ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP) connection to each directly connected member. QFX5100-24Q devices are recommended in the primary, backup, or line card role. When mixed with QFX3500 or QFX3600 devices, configure the QFX5100-24Q device in the primary and backup roles. See Connecting QFX Series and EX Series Switches in a QFX Virtual Chassis for cabling diagrams. The Virtual Chassis feature is not applicable to QFX devices in a QFabric.

To connect a QFX5100-24Q device as a spine or leaf device in a QFX5100 VCF, you need to cable a set of ports as VCP connections that link each spine device and leaf device. All spine devices have at least one direct VCP connection to each leaf device in the VCF. Non-channelized DAC cables can be configured as VCP connections. See Connecting a QFX5100 Device in a Virtual Chassis Fabric for a cabling diagram.

Best Practice

Whenever possible use the QFX5100-24Q device as a spine device. By using the QFX5100-24Q device in a maximum configuration of 20 total devices, four QFX5100-24Q devices may be used as spine devices. All members can be connected to the spine using QSFP+ ports.

As of Junos OS release 17.3R1, you can also connect a QFX5100-24Q as a leaf device in a QFX5110 VCF or as a member in a QFX5110 Virtual Chassis.

Port Panel of a QFX5100-24Q-AA Device

The port panel of the QFX5100-24Q-AA switch consists of 24 quad small-form factor pluggable plus (QSFP+) 40-Gigabit Ethernet ports. Each QSFP+ socket can be configured to support 40-Gigabit Ethernet or as a set of four independent 10-Gigabit Ethernet ports using breakout cables (channelization mode). The QFX5100-24Q-AA can also be configured to support 96 10-Gigabit Ethernet ports using breakout cables (channelization mode) with 1280 Gbps output. Any of the 24 ports can be configured as either an uplink port or an access port.

The expansion module bay of the QFX5100-24Q switch is located on the port panel. In the expansion module bay, you can install a single double-wide expansion module (QFX-PFA-4Q) or two single-wide optional expansion modules (QFX-EM-4Q and EX4600-EM-8F, in any combination). When you install two single-wide expansion modules, the slot on your left hand side is slot 1 (QIC0), and the slot on your right hand side is slot 2 (QIC1).

The QFX-PFA-4Q module adds four QSFP+ ports to the chassis. The QFX-EM-4Q module adds four QSFP+ ports to the chassis and the EX4600-EM-8F module adds eight 10-Gigabit SFP+ ports to the chassis. The QFX-EM-4Q ports can be configured as either access ports or as uplinks ports, but only ports 0 and 2 can be channelized by using port mode. The QFX-EM-4Q ports can also be configured as either access ports or uplink ports, but only ports 0 and 2 can be channelized by using port mode. Figure 3 shows the port panel of the QFX5100-24Q-AA device.

Port Panel of QFX5100-48S and QFX5100-48SH Devices

The port panel of the QFX5100-48S and QFX5100-48SH switches supports up to a maximum of 72 logical 10 GbE ports when operating as a standalone switch. Forty-eight physical ports(0 through 47) support 10 Gigabit Ethernet small form-factor pluggable plus (SFP+) transceivers. These ports can also support 1 Gigabit SFP transceivers and can be configured at either 1 Gbps or 1 Gbps speeds using the set interface speed command. All 48 of these ports can be used for SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP+, 10-Gigabit Ethernet SFP+ transceivers and SFP+ DAC cables in any access port.

The remaining 24 logical ports are the six 40 GbE physical ports (48 through 53) that support up to 6 quad small-form factor pluggable plus (QSFP+) transceivers . Each QSFP+ socket can operate either as a single 40 Gbps port or as a set of 4 independent 10 Gbps ports using QSFP+ breakout cables. The 40 GbE ports can be configured as either access ports or as uplinks.

Caution

Do not install 1GbE copper transceivers (such as QFX-SFP-1GE-T) directly above or below another 1GbE copper transceiver. Use only the top row or bottom row to avoid damage to the device caused by some types of copper transceivers when the transceivers are installed above or below each other. However, if you are using copper transceivers with the OEM part number FCLF8521P2BTL-J1 printed on the transceiver label, you can install the transceivers in any port with no restrictions. For devices that support 10GbE copper transceivers, there is no similar restriction.

To connect a QFX5100-48S switch as a node device in a QFabric system, you need:

  • Four QSFP+ uplink ports on each QFX5100-48S Node device to connect to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect devices.

  • The two remaining QSFP+ uplink ports on each QFX5100-48S Node device connect to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect devices. See Determining Interface Support for the QFX5100 Device.

To connect a QFX5100-48S switch as a member in a QFX Virtual Chassis, you need a pair of dedicated ports and cables that link each member in the Virtual Chassis into a ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP) connection to a upstream and downstream member. QFX5100-48S switches are recommended in the primary, backup, or line card role. When mixed with QFX3500 or QFX3600 devices, configure the QFX5100-48S in the primary and backup roles. See Connecting QFX Series and EX Series Switches in a QFX Virtual Chassis for cabling diagrams.

To connect a QFX5100-48S switch as a spine or leaf device in a QFX5100 Virtual Chassis Fabric (VCF), you need a pair of dedicated ports and cables that link each spine device and leaf device in the VCF. All spine devices have at least one direct VCP connection to each leaf device in the VCF. See Connecting a QFX5100 Device in a Virtual Chassis Fabric for a cabling diagram.

Best Practice

In a mixed QFX5100 VCF environment with multiple models of QFX5100 and the EX4300, use QFX5100-24Q as spine devices. In the maximum configuration of 20 total devices, up to four QFX5100-24Q devices may be used as spine devices. All members can be connected to the spine using QSFP+ ports. You can configure the QFX5100-96S as a spine in an all QFX5100-96S VCF or in a mixed VCF comprised of EX4300 and QFX5100-96S.

As of Junos OS release 17.3R1, you can also connect a QFX5100-48S as a leaf device in a QFX5110 VCF or as a member in a QFX5110 Virtual Chassis.

The port panel of the QFX5100-48T and QFX5100-48TH devices supports 48 10GBASE-T ports and 6 quad small-form factor pluggable (QSFP+) ports. Forty-eight copper physical ports (0 through 47) are tri-speed and support up to 10-Gigabit Ethernet. These 10GbE/1GbE/100 Mbps ports can be configured as access ports. See Determining Interface Support for the QFX5100 Device.

The remaining six ports (48 through 53), support 40 GbE QSFP+ transceivers. Each QSFP+ socket can operate either as a single 40 Gbps port or as a set of 4 independent 10 Gbps ports using QSFP+ breakout cables. The 40 GbE ports can be configured as either access ports or as uplinks.

To connect a QFX5100-48T device as a member in a QFX Virtual Chassis, you need a pair of dedicated ports and cables that link each member in the Virtual Chassis into a ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP) connection to a upstream and downstream member. QFX5100-48T switches are recommended in the primary, backup, or line card role. When mixed with QFX3500 or QFX3600 devices, configure the QFX5100-48T device in the primary and backup roles. See Connecting QFX Series and EX Series Switches in a QFX Virtual Chassis for cabling diagrams.

To connect a QFX5100-48T device as a leaf device in a Virtual Chassis Fabric (VCF), you need a pair of dedicated ports and cables that link each spine device and leaf device in the VCF. All spine devices have at least one direct VCP connection to each leaf device in the VCF. See Connecting a QFX5100 Device in a Virtual Chassis Fabric for a cabling diagram.

The QFX5100-48T device operates as a standalone switch, a member of a QFX Virtual Chassis, a member of a QFX5110 Virtual Chassis, act as a leaf device in a Juniper Networks Virtual Chassis Fabric (VCF). QFX Virtual Chassis and QFX5100 Virtual Chassis both support up to 10 members. VCF supports 20 total devices, of which 4 QFX5100-24Q devices can be configured as spine devices.

Best Practice

Use the QFX5100-24Q as a spine device and any QFX5100 device (except QFX5100-24Q-AA, QFX5100-48TH, or QFX510048SH) as leaf devices.

Switch Ports

The QFX5100-96S switch ports, (0 through 95) support:

  • SFP transceivers that can run at either 100 Mbps or 1 Gbps speed

  • SFP+ transceivers at 10 Gbps speed

  • SFP to SFP direct attach copper (DAC) cables

  • SFP+ to SFP+ DAC cables

  • SFP+ to SFP+ active optical cables (AOC)

Ports 96 through 104 support:

  • 40 Gbps QSFP+ transceivers

Additionally ports 96 and 100 support:

  • SFP+ transceivers

  • QSFP+ to QSFP+ direct attach copper (DAC) cables

  • QSFP+ to SFP+ DAC breakout cables (DACBO)

  • QSFP+ to QSFP+ active optical cables (AOC)

  • QSFP+ to SFP+ AOC breakout cables (AOCBO)

Caution

Do not install 1GbE copper transceivers (such as QFX-SFP-1GE-T) directly above or below another 1GbE copper transceiver. Use only the top row or bottom row to avoid damage to the device caused by some types of copper transceivers when the transceivers are installed above or below each other. However, if you are using copper transceivers with the OEM part number FCLF8521P2BTL-J1 printed on the transceiver label, you can install the transceivers in any port with no restrictions. For devices that support 10GbE copper transceivers, there is no similar restriction.

Channelizing Interfaces

The port panel of the QFX5100-96S switch supports up to a maximum of 104 logical 10 GbE ports that can be distributed over 96 small form-factor pluggable plus (SFP+) and 8 quad small-form factor pluggable plus (QSFP+) transceivers . Because of an 104 port restriction, only two of the eight QSFP+ can be channelized. Depending on how you set the system mode for channelization, the behavior of channelization for the QSFP+ changes. The following system modes are available for the QFX5100-96S switch:

  • Non-oversubscribed

    All 96 SFP+ ports on the switch (PIC 0) are supported. In this mode, the eight QSFP+ ports are not supported and cannot be channelized. There is no packet loss for packets of any size in this mode.

  • Default mode

    All 96 SFP+ ports on the switch (PIC 0) are supported. QSFP+ ports 96 and 100 can be channelized. If ports 96 and 100 are channelized, the interfaces on ports 97, 98, 99, 101, 102, and 103 are disabled.

Virtual Chassis and Virtual Chassis Fabric Support

The QFX5100-96S switch operates as a standalone switch, as a member in a QFX Virtual Chassis, as a member in a QFX5110 Virtual Chassis, as a spine or leaf device in a QFX5100 Virtual Chassis Fabric (VCF), or as a leaf device in a QFX5110 VCF. QFX Virtual Chassis support up to 10 members; QFX5100 VCF supports a total of 20 devices, of which 4 QFX5100 devices can be configured as spines. A QFX Virtual Chassis is cabled in a ring topology, where a VCF is cabled in a spine and leaf topology.

Virtual Chassis

In a QFX Virtual Chassis, you can connect up to 10 standalone QFX5100-96S switches into a QFX Series Virtual Chassis and manage the interconnected switches as a single chassis. The advantages of connecting multiple switches into a Virtual Chassis include better-managed bandwidth at a network layer, simplified configuration and maintenance because multiple devices can be managed as a single device, increased fault tolerance and high availability (HA) because a Virtual Chassis can remain active and network traffic can be redirected to other member switches when a single member switch fails, and a flatter, simplified Layer 2 network topology that minimizes or eliminates the need for loop prevention protocols such as Spanning Tree Protocol (STP).

As of Junos OS release 17.3R1, you can also connect a QFX5100-96S as a member in a QFX5110 Virtual Chassis.

Virtual Chassis Fabric

The VCF provides a low-latency, high-performance fabric architecture that can be managed as a single device. VCF is an evolution of the Virtual Chassis feature, which allows you to interconnect multiple devices into a single logical device, inside of a fabric architecture. The VCF architecture is optimized to support small and medium-sized data centers that contain a mix of 1-Gpbs, 10-Gpbs, and 40-Gbps Ethernet interfaces.

A VCF is constructed using a spine-and-leaf architecture and topology. In the spine-and-leaf architecture, each spine device is interconnected to each leaf device. A VCF supports up to 20 devices, of which 4 QFX5100 devices can be configured into spine devices. In a mixed environment with QFX5100-24Q, QFX5100-98S and EX4300, use the QFX5100-24Q as the spine device and the QFX5100-96S and EX4300 as a leaf devices. You may use the QFX5100-96S as a spine in an all QFX5100-96S VCF or in a VCF that has a mixture of QFX5100-96S and EX4300.

As of Junos OS release 17.3R1, you can also connect a QFX5100-24Q as a leaf device in a QFX5110 VCF.

Expansion Modules for QFX5100 Devices

The QFX5100-24Q and QFX5100-24Q-AA devices have two bays on the port panel for optional expansion modules. These expansion modules can be hot-inserted or hot-removed. Expansion modules and transceivers are not shipped with the switch and must be ordered separately.

The QFX5100-24Q and QFX5100-24Q-AA support these expansion modules up to the 104-port limitation:

  • Two EX4600-EM-8F, which provides a total of 16 additional 10-Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) ports or 8 additional 1-Gigabit SFP ports. When both bays (PIC 1 and PIC 2) are populated with EX4600-EM-8F modules, you must configure the system mode as Flexi-pic. In this mode, port 0 to 3 of PIC 0 are disabled, which allows the devices to operate within the 104-port limitation.

  • Two QFX-EM-4Q, which provides a total of 8 additional 40-Gigabit Quad SFP+ (QSFP+) ports.

  • One EX4600-EM-8F and one QFX-EM-4Q, which provides 8 additional 10-Gigabit Ethernet SFP+ (or 8 additional 1-Gigabit SFP ports) and 4 additional 40-Gigabit (QSFP+) ports. This combination requires the system mode to be configured as Flexi-pic. See Configuring the System Mode.

Additionally, the QFX5100-24Q-AA supports the QFX-PFA-4Q expansion module, which provides 4 additional QSFP+ ports.

Note

In order to run the orchestration diagnostics, Precision Time Protocol (PTP) and synchronization diagnostics, and utilities contained in the Packet Flow Accelerator Diagnostics software, you must have Junos OS Release 14.1X53-D27 or later software with enhanced automation installed on your QFX5100-24Q-AA.

EX4600-EM-8F

The EX4600-EM-8F is a MACsec-capable expansion module that inserts into one of the device bays of a QFX5100-24Q, QFX5100-24Q-AA, or an EX4600 switch. It provides 8 additional 10-Gigabit Ethernet SFP+ ports or 8 additional 1-Gigabit SFP ports to each bay. Figure 7 shows the ports and LEDs on the expansion module.

Caution

Copper SFP transceivers (1000BASE-T) are restricted to the top four ports or the bottom four ports; fiber SFP transceivers (1000BASE-X) can be used in any of the eight ports. Attempting to stack copper SFP transceivers causes internal damage to the module.

When the expansion module is inserted into the expansion bay, the chassis detects the additional ports, recognizes them as 10GbE ports, and lights the Status LED. The QFX5100-24Q device is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-4Q is inserted instead of the default QFX-EM-4Q, the Packet Forwarding Engine reboots that can cause some temporary disruption in traffic. See Configuring the System Mode.

Note

MACsec is supported on the 10-Gigabit Ethernet ports with the EX-QFX-MACSEC-AGG license.

QFX-EM-4Q

The QFX-EM-4Q, provides 4 additional 40-Gigabit Ethernet QSFP+ ports to one of the bays in the QFX5100-24Q or QFX5100-24Q-AA. Port 0 and port 2 can be used for port channelization by configuring the system mode for 104 port mode.

Figure 8 shows the QFX-EM-4Q ports and LEDs.

Note

If a QFX-EM-4Q is installed in PIC1 and EX4600-EM-8F is installed in PIC2, you must configure the system mode to be Flexi-PIC. Otherwise, only the EQF-EM-4Q is recognized by the software.
