Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
For class-based features (such as marking, Modified Deficit Round Robin [MDRR], and policing), you define
traffic classes based on match criteria, including ACLs and input interfaces. Packets satisfying the match
criteria for a class constitute the traffic for that class.
The match access-group command specifies an ACL whose contents are used as the match criteria against
which packets are checked to determine if they belong to the class specified by the class map.
Access Control Entries with TCP fields such as, SYN, ACK and FIN in the corresponding ACL are not
supported.
