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

PFC is disabled on Ethernet interfaces.

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.
Examples
# Configure Ten-GigabitEthernet 1/1/5 to automatically negotiate with its peer to enable PFC.
