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 -
Σ
pfc 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
