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

Observe that PFC for PG 1 is enabled.
6. Save the configuration.

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
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.
