QoS Classification Commands

match access-group

To identify a specified access control list (ACL) number as the match criteria for a class map, use the match
access-group command in class map configuration mode.
match access-group {ipv4|ipv6} access-group-name
Syntax Description
ipv4
ipv6
access-group-name
By default, if neither IPv6 nor IPv4 is specified as the match criteria for a class map, IPv4 addressing is used.

For class-based features (such as marking and policing), you define traffic classes based on match criteria,
Usage Guidelines
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.
The match access-group command is supported only in the ingress direction. The maximum allowed entries:
8
To use the match access-group command, you must first enter the class-map command to specify the
name of the class whose match criteria you want to establish. You can specify up to eight IPv4 and IPv6 ACLs
in a match statement.
QoS classification based on the packet length or TTL (time to live) field in the IPv4 and IPv6 headers is not
supported.
When an ACL list is used within a class-map, the deny action of the ACL is ignored and the traffic is classified
based on the specified ACL match parameters.

match criteria for this class:
Specifies the name of the IPv4 access group to be matched.
Specifies the name of the IPv6 access group to be matched.
ACL whose contents are used as the match criteria against which packets are checked
to determine if they belong to this class.
