priority-flow-control Use priority-flow-control to enable PFC on an Ethernet interface through automatic negotiation or forcibly. Use undo priority-flow-control to disable PFC on the interface. Syntax priority-flow-control { auto | enable } undo priority-flow-control Default PFC is disabled on Ethernet interfaces. Views Ethernet interface view Predefined user roles network-admin Parameters auto: Specifies the Ethernet interface to automatically negotiate with its peer to enable PFC. enable: Forcibly enables PFC. Usage guidelines A port can receive PFC pause frames regardless of whether PFC is enabled on the port. However, only a port with PFC enabled can process PFC pause frames. Therefore, to make PFC take effect, make sure that PFC is enabled on both the local end and the peer end.
