Usage
Information
If you configure PFC on a 40GbE port, count the 40GbE port as four PFC-enabled
ports in the pfc-port number you enter in the command syntax.
To achieve lossless PFC operation, the PFC port count and queue number used for
the reserved buffer size that is created must be greater than or equal to the buffer
size required for PFC-enabled ports and lossless queues on the switch.
You must reload the stack or a specified stack unit (use the reload command in
EXEC Privilege mode) for the PFC buffer configuration to take effect.
