priority-flow-control

Enables PFC on ingress interfaces.

Syntax
priority-flow-control {mode on}
Parameter
mode on — Enable PFC for FCoE and iSCSI traffic 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 specific 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 flow 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
