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