Usage Configure the maximum shared buffer available for PFC traffic. You can choose to
Information increase or decrease the shared buffer that is currently allocated in the system by
default. 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 validation 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 as follows:
S4810-YU-MR-FTOS (conf)#dcb pfc-shared-buffer-size 2000
%ERROR: pfc shared buffer size configured cannot accommodate
existing buffer requirement in the system.
Example
Dell(conf)#dcb pfc-shared-buffer-size 5000
