priority-ow-control
Enables PFC on ingress interfaces.
Syntax
priority-flow-control {mode on}
Parameter mode on — Enable PFC for FCoE and iSCSI trac on an interface without enabling DCBX.
Default Disabled
Command Mode INTERFACE
Usage Information Before you enable PFC, apply a network-qos policy-class map with the specic PFC dot1p priority values to the
interface. In the PFC network-qos policy-class map, use the default buffer-size values if you are not sure
about the pause-threshold, and resume-threshold settings that you want to use. You cannot enable PFC
and link-layer ow control (LLFC) at the same time on an interface. The
no version of this command disables PFC
on an interface. When you disable PFC, remove the PFC network-qos policy-class map applied to the interface.
Example
OS10(conf-if-eth1/1/1)# priority-flow-control mode on
Supported Releases 10.3.0E or later

Parameters None
Default Not congured
Command Mode EXEC
Usage Information Use the details option to display PFC statistics on received/transmitted frames for each dot1p (CoS) value, and
use the clear qos statistics interface ethernet 1/1/1 command to delete PFC statistics and
restart the counter.
