port-pfc-create
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 configure PFC on ports.
Syntax port-pfc-create
priority priority |
Specify a priority for PFC. This is a number between 0 and 7. |
port-list port-list |
Specify a port list to apply PFC. |
Defaults None
Access Network administrator
History Command introduced in Version 2.5.4.
Usage This command is used to set PFC for link level flow control for traffic on the network.
Examples To create a new PFC configuration on port 2 with a priority group of 2, use the following command:
CLI (network-admin@Spine1)port-pfc-create priority 2 port 1-10 Priority configuration will be effective after restart.

CLI network-admin@switch > port-pfc-modify priority 2 port 11-15
Priority configuration will be effective after restart.
