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.
