disable and re-enable DCB. For example, if you modify the total buffer size to be
4000 KB from the previous size of 5000 KB, an error message is displayed that this
reduction cannot be performed owing to existing system configuration because of
queues that are being currently processed.
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.
