Enabling priority flow control on an interface

Follow these steps to enable PFC on an interface.

Note: PFC is supported only on Ruckus ICX 7250 and ICX 7450 devices. The ICX 7150, ICX 7650, and the ICX 7850 devices do not support PFC.
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
     port-name ERSPAN
     dual-mode

     priority-flow-control enable

    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
