For each priority, you can specify the shared buffer threshold limit, the ingress

buffer size, buffer limit for pausing the acceptance of packets, and the buffer offset

limit for resuming the acceptance of received packets. When PFC detects

congestion on a queue for a specified priority, it sends a pause frame for the

802.1p priority traffic to the transmitting device.

You can use theprioritycommand to set up both the administrative and peer-

related PFC priorities. For example, you can configure the intended buffer

configuration for all eight priorities. If you configure the number of lossless queues

as 4 and if the administrator-configured priorities configured within the DCB input

policy is applied, then the configuration for those priorities are pre-designed.

However, if the peer-provided priorities are applied, although a DCB input policy is

present, the peer-provided priorities become effective for buffer configuration.

This method of configuration provides an easy and flexible technique to

accommodate both administratively-configured and peer-configured priorities.
