Usage Information
Configure the maximum shared buffer available for PFC traffic. You can choose to increase or decrease the
shared buffer that is allocated in the system by default. Configure the shared buffer size less than the total PFC
buffer size. If the shared buffer size is more than the total PFC buffer size value, the configuration is not saved
and a system logging message is generated.

% Error: Shared buffer size cannot be greater than the the available buffer
in the system
DellEMC(conf)#
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.
