Dcb Stack-Unit Pfc-Buffering Pfc-Port-Count Pfc-Queues - Dell MXL 10GbE Reference Manual

dcb stack-unit pfc-buffering pfc-port-count 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.
Syntax
dcb stack-unit stack-unit-id [port-set port-set-id] pfc-
buffering pfc-ports {1-56} pfc-queues {1-2}
To remove the configuration for the PFC buffer on all port pipes in a specified stack
unit, use the no dcb stack-unit stack-unit-id [port-set port-set-
id] pfc-buffering pfc-ports pfc-queues command.
Parameters

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.
