Only one match criterion per class map is supported, and only one
ACL per class map is supported.

For access-group acl-index-or-name, specify the number or
name of the ACL created in Step 2.
•
To filter IPv6 traffic with the match access-group command,
create an IPv6 ACL, as described in Step 2.
•
For ip dscp dscp-list, enter a list of up to eight IP DSCP values
to match against incoming packets. Separate each value with a
space. The range is 0 to 63.
•
For ip precedence ip-precedence-list, enter a list of up to eight
IP-precedence values to match against incoming packets.
Separate each value with a space. The range is 0 to 7.

class-map configuration command.
