Configure the maximum buffer available for PFC traffic. You can choose to increase or decrease the buffer size that is currently allocated in the system by default. However, if you modify the PFC buffer size to be lower than the previously configured PFC buffer size, the system determines whether this reduction in size is valid without disrupting the existing configuration. In such a scenario, you must 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-queuescommand. 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.
