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.

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

    For example, to configure ports Q4 through Q5 to operate as 40-Gigabit Ethernet interfaces (xle):

  2. To configure a block of ports to operate as 40-Gigabit Ethernet data plane uplink interfaces (fte), specify a port range:

    For example, to configure ports Q4 through Q5 to operate as 40-Gigabit Ethernet data plane uplink interfaces (fte):

  3. To configure an individual port to operate as a 40-Gigabit Ethernet data plane uplink interfaces (fte), specify a port number:

    For example, to configure port Q4 to operate as a 40-Gigabit Ethernet data plane uplink interfaces (fte):

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

    For example, to delete the 40-Gigabit Ethernet access interface (xle) port configuration for ports Q2 through Q3:

  6. To delete an individual port configured as a 40-Gigabit Ethernet (xle) interface:

    For example, to delete the 40-Gigabit Ethernet interface (xle) for port Q2:

  7. To delete a block of ports configured as 40-Gigabit Ethernet data plane uplink interfaces (fte), specify a port range:

    For example, to delete the block of ports configured as 40-Gigabit Ethernet data plane uplink interfaces (fte) for ports Q4 through Q5:

  8. To delete an individual port configured as a 40-Gigabit Ethernet data plane uplink interfaces (fte):

    For example, to delete the 40-Gigabit Ethernet data plane uplink interfaces (fte) for port Q4:

  9. Review your configuration and issue the commit command.
