The full name of pfc is priority flow control. This command define pfc is applied in a specified port. Pfc acts on packets entering the port, similar to flow control. But flow control only works on the port. It can't work on the code point.
When flow control has been configured on the port, configure pfc. Because pfc has higher priority than flow control, flow control will become invalid on the port.
set class-of–service interface <port> pfc-profile <profile-name>
delete class-of–service interface <port> pfc-profile
