Administrator Guide

The lossless queue limit per port is validated based on the dcb pfc-queues command. PFC queue
configuration identifies the maximum number of queues a port can support. Although the queue limit per
port is a baseline when dynamic buffering is enabled, the limit per port for queues depends on the
availability of the buffer.
Example
Dell(conf)#dcb pfc-total-buffer-size 5000
Dell(conf)#dcb pfc-total-buffer-size 4000
%ERROR: Total pfc buffer size configured cannot accommodate existing
buffer requirement in the system.
