pfc-cos

Configures the matching dot1p values that are used to send PFC pause frames.

Syntax
pfc-cos dot1p-priority
Parameters
dot1p-priority — Enter the dot1p priority value for a PFC traffic class, from 1 to 7. Use a comma (,) to separate multiple values or a hyphen ( - ) to specify a range of values; for example, 0, 3, 7, or 3-6.
Default
Not configured
Command Mode
POLICY-CLASS NETWORK-QOS
Usage Information
When you enter PFC-enabled dot1p priorities with pfc-cos, the dot1p values must be the same as the match qos-group (traffic class) numbers in the network-qos class map that is used to define the PFC traffic class, see Configure PFC Example. A qos-group number is used only internally to classify ingress traffic classes. For the default dot1p-priority-to-traffic-class mapping and how to configure a nondefault mapping, see PFC configuration notes. A PFC traffic class requires a 1-to-1 mapping — only one dot1p value is mapped to a qos-group number.
Example 
OS10(config)# class-map type network-qos cc1
OS10(conf-cmap-nqos)# match qos-group 3
OS10(conf-cmap-nqos)# exit
Example (policy-map) 
OS10(config)# policy-map type network-qos pp1
OS10(conf-pmap-network-qos)# class cc1
OS10(conf-pmap-c-nqos)# pfc-cos 3
