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.
DellEMC(conf)#dcb pfc-shared-buffer-size 3000
