Introduced on MXL 10/40GbE Switch IO Module Usage If you configure PFC on a 40GbE port, count the 40GbE port as four PFC-enabled ports in the pfc-port Information 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. Related Commands dcb stack-unit pfc-buffering pfc-port pfc-queues Configure the PFC buffer for all port pipes in a specified stack unit. dcb stack-unit pfc-buffering pfc-port pfc-queues Configure the PFC buffer for all port pipes in a specified stack unit by specifying the port-pipe number, number of PFC-enabled ports, and number of configured lossless queues.
