Classifying Traffic By Using Class Maps And Filtering Ipv6 Traffic - Cisco WS-CBS3032-DEL Software Configuration Manual

Chapter 37 Configuring QoS
This example shows how to create a class map called class2, which matches incoming traffic with DSCP
values of 10, 11, and 12.
Switch(config)# class-map class2
Switch(config-cmap)# match ip dscp 10 11 12
Switch(config-cmap)# end
Switch#
This example shows how to create a class map called class3, which matches incoming traffic with
IP-precedence values of 5, 6, and 7:
Switch(config)# class-map class3
Switch(config-cmap)# match ip precedence 5 6 7
Switch(config-cmap)# end
Switch#

Classifying Traffic by Using Class Maps and Filtering IPv6 Traffic

In Cisco IOS Release 12.2(52)SE and later, the switch supports both IPv4 and IPv6 QoS when the dual
IPv4 and IPv6 SDM template is configured. When the dual IP SDM template is configured, the match
ip dscp and match ip precedence classifications match both IPv4 and IPv6 traffic. The match protocol
command allows you to create a secondary match classification that filters traffic by IP version (IPv4 or
IPv6).
To apply the primary match criteria to only IPv4 traffic, use the match protocol command with the ip
keyword. To apply the primary match criteria to only IPv6 traffic, use the match protocol command with
the ipv6 keyword. For more information about the match protocol command, see the
of Service Solutions Command
Beginning in privileged EXEC mode, follow these steps to create a class map, define the match criterion
to classify traffic, and filter IPv6 traffic:
Command
Step 1
configure terminal
Step 2 class-map {match-all} class-map-name
Step 3 match protocol [ip | ipv6]
OL-13270-06
Reference.
Purpose
Enter global configuration mode.
Create a class map, and enter class-map configuration mode.
By default, no class maps are defined.
When you use the match protocol command, only the match-all
keyword is supported.
For class-map-name, specify the name of the class map.
•
If neither the match-all or match-any keyword is specified, the default
is match-all.
(Optional) Specify the IP protocol to which the class map applies:
Use the argument ip to specify IPv4 traffic and ipv6 to specify IPv6
•
traffic.
When you use the match protocol command, only the match-all
•
keyword is supported for the class-map command.
This command is available only when the dual IPv4 and IPv6
Note
SDM template is configured.
