Usage
Information
The dcb-map stack-unit all stack-ports all command overwrites any
previous DCB maps applied to stack ports.
dcb pfc-shared-buffer-size
Configure the maximum amount of shared buffer size for PFC packets in kilobytes.
You must configure the shared buffer size to be less than the total PFC buffer size. If the buffer size and
DCB buffer threshold settings are applied on one or more ports, a validaiton is performed to determine
whether following condition is satisfied: Shared-pfc-buffer-size <= (Total-pfc-buffer-size - Σpfc priority
<> buffer-size on each port, priority).
If the preceding condition is not satisfied by the shared PFC buffer size value, the configuration is not
saved and a system logging message is generated stating that the shared buffer size that you attempt to
specify cannot be configured because of the existing total buffer space on the system being lower than
the shared buffer size. You must either enter a smaller value for the shared buffer size or increase the
total buffer size appropriately by using the dcb pfc-total- buffer-size command.
