port-pfc-stats-settings-show
Priority Flow Control (PFC) is an IEEE standard (802.1qbb) for link level flow control on Ethernet networks. Functionally, this feature is similar to the IEEE standard 802.3 for PAUSE mechanism, except that it operates at the granularity of individual packet priorities or traffic class, instead of port level. When a queue corresponding to traffic with a particular traffic class reaches a predetermined, either auto or statically set, threshold, the switch chip generates a PFC frame, and sends it back to the sender. For PFC to work effectively end to end on the network, all switches, and hosts in the traffic path are configured to enable PFC, and configured for traffic class to priority mappings.
This command allows you to display PFC stats on ports.
