Enabling priority flow control on multiple ports

Follow these steps to enable PFC on multiple ports.

Note: PFC is supported only on RUCKUS ICX 7250, ICX 7450, and ICX 7750 devices. The ICX 7150, ICX 7650, ICX 7850, and ICX 7550 devices do not support PFC.

PFC must be enabled on at least one PG before you can configure this feature on an interface.
  1. Enter global configuration mode. 
    device# configure terminal
  2. Enter interface configuration mode for multiple interfaces. 
    device(config)# interface ethernet 1/1/2 ethernet 1/1/3
  3. Enable PFC on the interfaces. 
    device(config-mif-1/1/2,1/1/4)# priority-flow-control enable
  4. Enter interface configuration mode for a range of interfaces. 
    device(config-mif-1/1/2,1/1/4)# interface ethernet 1/1/17 to 1/1/20
  5. Enable PFC on the interfaces. 
    device(config-mif-1/1/17-1/1/24)# priority-flow-control enable
  6. Return to privileged EXEC mode. 
    device(config-mif-1/1/32-1/1/43)# end
  7. Verify the configuration. 
    device# show running-config interface ethernet 1/1/2 ethernet 1/1/4
interface ethernet 1/1/2
 ip address 1.1.1.1 255.255.255.0
 ip address 2.2.2.2 255.255.255.0

  8. Save the configuration. 
    device# write memory

Enable priority flow control on multiple ports configuration example

device# configure terminal
device(config)# interface ethernet 1/1/2 ethernet 1/1/3
device(config-mif-1/1/2,1/1/4)# priority-flow-control enable
device(config-mif-1/1/2,1/1/4)# interface ethernet 1/1/17 to 1/1/20
device(config-mif-1/1/17-1/1/24)# priority-flow-control enable
device(config-mif-1/1/32-1/1/43)# end
device# show running-config interface ethernet 1/1/2 ethernet 1/1/4
device# show running-config interface ethernet 1/1/17 to 1/1/20
device# write memory
