Port Speed on QFX Switches

To view the supported transceivers, optical interfaces, and DAC cables on QFX5100-24Q, see Hardware Compatibility Tool (HCT).

For more information on QFX5100-24Q switches, see QFX5100 Switch Hardware Guide.

Table 1: Port Speed on QFX5100-24Q Switches

PIC 0	Port Number	Port Speeds Supported
PIC 0	0-23 (QSFP+ ports)	40 Gbps QSFP+ supports channelization into 4x10 Gbps using breakout cables.

Use the speed command to set the speed on tri-rate copper SFP port. For information on how to configure the speed at the PIC level, see Table 2. For information on how to configure the speed at the port level, see Table 3.

Guidelines:

• In standalone mode, any of the 24 ports 0 through 23 can be configured as either uplink or access ports.

• You can use 40-Gigabit Ethernet QSFP+ transceivers and QSFP+ direct attach copper cables in any downstream port.

• You can configure up to 4 of the 40 Gbps ports as uplinks.

• The QFX5100-24Q device has two module bays for the optional expansion modules, QFX-EM-4Q or EX4600-EM-8F. QFX-EM-4Q can add a total of 8 additional QSFP+ ports to the chassis and EX4600-EM-8F can provide 8 additional 10 Gbps Enhanced SFP+ ports. The QFX-EM-4Q ports can also be configured as either access ports or as uplink ports, but only ports 0 and 2 can be channelized using port mode.

• When fully populated with two 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.

• 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 four QFX5100 devices can be configured as spines.
