port-pfc-delete

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 delete PFC configurations on ports.

Syntax   port-pfc-delete priority priority 

priority priority

Specify a priority for PFC. This is a number between 0 and 7.

Defaults   None

Access   Network administrator

History   Command introduced in Version 2.5.4.

Usage   This command is used to delete a PFC priority for link level flow control for traffic on the network.

Examples  To delete the PFC priority 2, use the following command:

CLI network-admin@switch > port-pfc-delete priority 2
