Enabling priority flow control on an interface

Follow these steps to enable PFC on an interface.
Note: PFC is supported on RUCKUS ICX 7250, ICX 7450, and ICX 7850 devices. However, PFC is not supported at the interface level on ICX 7850.
PFC must be enabled on at least one PG before you can use this command to configure an interface.
  1. Enter global configuration mode. 
    device# configure terminal
  2. Enable interface configuration mode. 
    device(config)# interface ethernet 1/1/1
  3. Enable PFC on the interface. 
    device(config-if-e10000-1/1/1)# priority-flow-control enable
  4. Return to privileged EXEC mode. 
    device(config-if-e10000-1/1/1)# exit
  5. Verify the configuration. 
    device# show running-config interface ethernet 1/1/1
interface ethernet 1/1/1

    Observe that PFC for PG 1 is enabled.
  6. Save the configuration. 
    device# write memory

Enable PFC on an interface configuration example

device# configure terminal
device(config)# interface ethernet 1/1/1
device(config-if-e10000-1/1/1)# priority-flow-control enable
device(config-if-e10000-1/1/1)# exit
device# show running-config interface ethernet 1/1/1
device# write memory
