Usage
Information
In a match-any class, you can enter multiple match criteria. In a match-all class, if the match case is
access-group, no other match criteria is allowed. If you attach the access-list to class-map type
control—plane or qos, the access-list (IPv4, IPv6) ignores the permit and deny keywords.
Example 1
OS10(conf-cmap-qos)# match ip access-group name ag1
OS10(config-cmap-qos)# match ipv6 access-group name ACLv6
Example 2
OS10(config)# class-map type control-plane example-queue-remap
OS10(config-cmap-control-plane)# match vrrp
