Users Guide

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
