pfc-cos

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

Syntax
pfc-cos dot1p-priority
Parameters
dot1p-priority — Enter a single dot1p priority value for a PFC traffic class (1 to 7), a hyphen-separated range, or multiple dot1p values separated by commas.
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 used to define the PFC traffic class (see Configure PFC Example). A qos-group number is used only internally to classify ingress traffic classes. See PFC configuration notes for the default dot1p-priority-to-traffic-class mapping and how to configure a non-default mapping. 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
