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 the priority command 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.

Configuration)
Assign the DCB policy to the DCB buffer threshold profile on interfaces. This setting takes precedence over
the global buffer-threshold setting.
