match qos-group
match qos-group
To identify a specific quality of service (QoS) group value as a match criterion for a class, use the match
qos-group command in class-map configuration mode. To remove the match criteria, use the no form of
this command.
match qos-group value
no match qos-group value
Syntax Description
Defaults No match criterion are defined.
Command Modes Class-map configuration
Command History
Usage Guidelines The match qos-group command specifies a QoS group value to use as the match criterion to determine
if packets belong to the class specified by the class map.
The QoS-group values are used as marking only and have no mathematical significance. For example,
the precedence value of 2 is not greater than 1, but merely indicates that a packet marked with a value
of 2 is different than one marked with a value of 1. You define the treatment of these marked packets by
setting QoS policies in policy-map class configuration mode.
The QoS-group value is local to the switch, meaning that the QoS-group value marked on a packet does
not leave the switch when the packet leaves the switch. If you require a marking that remains with the
packet, use IP Differentiated Service Code Point (DSCP) values, IP precedence values, or another
method of packet marking.
Before using the match qos-group command, you must enter the class-map global configuration
command to specify the name of the class whose match criteria you want to establish.
You can use the match qos-group classification only on output policy maps.
There can be no more than 100 QoS groups on the switch (0 to 99).
You can verify the configuration by entering the show class-map privileged EXEC command.
Examples This example shows how to classify traffic by using QoS group 13 as the match criterion:
Switch(config)# class-map match-any inclass
Switch(config-cmap)# match qos-group 13
Switch(config-cmap)# exit
qos-group value A quality of service group value. The range is from 0 to 99.
