priority-flow-control Enables PFC on ingress interfaces. Syntax Parameter Default Command Mode Usage Information Example priority-flow-control {mode on} mode on - Enable PFC for FCoE and iSCSI traffic on an interface without enabling DCBX. Disabled INTERFACE 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. OS10(conf-if-eth1/1/1)# priority-flow-control mode on Supported Releases 10.3.0E or later queue-limit Sets the static and dynamic thresholds used to limit the shared-buffer size of PFC traffic-class queues. Syntax queue-limit {thresh-mode [static kilobytes | dynamic weight]} Parameters • thresh-mode - Buffer threshold mode. • static kilobytes - Enter the fixed shared-buffer limit available for PFC traffic-class queues in kilobytes (0 to 7787; maximum amount tuned by the pfc-shared-buffer-size command). • dynamic weight - Enter the weight value used to dynamically determine the shared-buffer limit available for PFC traffic-class queues (1 to 10). Default Command Mode Usage Information Example Dynamic weight of 9 and static shared-buffer limit of 12479488 kilobytes POLICY-CLASS NETWORK-QOS To tune the amount of shared buffers available for the static limit of PFC traffic-class queues on the switch, use the pfc-shared-buffer-size command. The dynamic queue-limit is determined by the current amount of available shared buffers.
