Usage Information Congure the maximum shared buer available for PFC trac. You can choose to increase or decrease the
shared buer that is currently allocated in the system by default. You must congure the shared buer size
to be less than the total PFC buer size. If the buer size and DCB buer threshold settings are applied on
one or more ports, a validation is performed to determine whether following condition is satised: If the
preceding condition is not satised by the shared PFC buer size value, the conguration is not saved and a
system logging message is generated as follows:
Shared-pfc-buer-size <= (Total-pfc-buer-size - Σpfc priority <> buer-size on each port, priority).
Dell(conf)#dcb pfc-shared-buffer-size 2000

buffer requirement in the system.
