QoS Classification Commands

match cos

To identify specified class of service (CoS) values as a match criteria in a class map, use the match cos
command in class map configuration mode. To remove a specified CoS class value from the matching criteria
for a class map, use the no form of this command.
match cos {cos-value [cos-value1 ... cos-value7]}
no match cos {cos-value [cos-value1 ... cos-value7]}
Syntax Description
cos-value
No match criteria are specified.

The match cos command is supported only in the ingress direction.
Usage Guidelines
The match cos command specifies a class of service that is used as the match criteria against which packets
are checked to determine if they belong to the class specified by the class map.
To use the match cos command, you must first enter the class-map command to specify the name of the
class whose match criteria you want to establish. If you specify more than one match cos command in a
class map, the values of subsequent match statements are added to the first match cos command.

Examples
This example shows how to configure the service policy called policy-in and attach service policy
policy-in to an interface HundredGigE 0/0/0/3. In this example, class map cos146 evaluates all
packets of service values of 1, 4, or 6. If the incoming packet has been marked with any of these CoS
values, the traffic is policed at 300 mbps.
RP/0/RP0/CPU0:router(config)# class-map cos146
RP/0/RP0/CPU0:router(config-cmap)# match cos 1 4 6
RP/0/RP0/CPU0:router(config-cmap)# exit
RP/0/RP0/CPU0:router(config)# policy-map policy-in
RP/0/RP0/CPU0:router(config-pmap)# class cos146
RP/0/RP0/CPU0:router(config-pmap-c)# police rate 300 mbps
RP/0/RP0/CPU0:router(config-pmap-police)#exit
RP/0/RP0/CPU0:router(config-pmap-c)# exit
RP/0/RP0/CPU0:router(config-pmap)# exit
Identifier that specifies the exact value from 0 to 7. Up to eight CoS identifiers can be specified
to match packets.
