Command Usage
â—† First enter the class-map command to designate a class map and enter the
Class Map configuration mode. Then use match commands to specify the fields
within ingress packets that must match to qualify for this class map.
â—† If an ingress packet matches an ACL specified by this command, any deny rules
included in the ACL will be ignored.
â—† If match criteria includes an IP ACL or IP priority rule, then a VLAN rule cannot
be included in the same class map.
â—† If match criteria includes a MAC ACL or VLAN rule, then neither an IP ACL nor IP
priority rule can be included in the same class map.
â—† Up to 16 match entries can be included in a class map.
