Kamal,
In the following example:
class-map match-all Interactive Video
match ip dscp af41 af42 ! Recommended markings for IP/VC
class-map match-any Call Signaling
match ip dscp cs3 ! Future Call-Signaling marking
match ip dscp af31 ! Current Call-Signaling marking
You are matching Video traffic which is af41 or af42 under the first
class-map, the second class-map would match Voice signaling based on cs3 or
af31 DSCP Value.
Up to eight IP DSCP values can be matched in one match statement. For
example, if you wanted the IP DCSP values of 0, 1, 2, 3, 4, 5, 6, or 7 (note
that only one of the IP DSCP values must be a successful match criterion,
not all of the specified IP DSCP values), enter the match ip dscp 0 1 2 3 4
5 6 7 command.
HTH,
Tarun Pahuja
