Multiple match Commands in One Traffic Class
If the traffic class contains more than one match command, you need to specify how to evaluate the match
commands. You specify this by using either the match-any or match-all keyword of the class-map command.
Note the following points about the match-any and match-all keywords:
• If you specify the match-any keyword, the traffic being evaluated by the traffic class must match one
• If you specify the match-all keyword, the traffic being evaluated by the traffic class must match all of
• If you do not specify either keyword, the traffic being evaluated by the traffic class must match all of

map to the interface (by using the service-policy command).
A packet can match only one traffic class within a traffic policy. If a packet matches more than one traffic
