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 set up both the administrative and peer-related PFC priorities. For
example, you can configure the intended buffer configuration for all 8 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.
Example
Dell(conf)# qos-policy-buffer test
Dell(conf-qos-policy-buffer)#queue 0 pause no-drop buffer-
size 128000 pause-threshold 103360 resume-threshold 83520
Dell(conf-qos-policy-buffer)# queue 4 pause no-drop buffer-
size 128000 pause-threshold 103360 resume-threshold 83520
dcb-policy buffer-threshold (Interface Configuration)
Assign the DCB policy to the DCB buffer threshold profile on interfaces. This setting takes precedence
over the global buffer-threshold setting.
