Command Usage
◆
First enter the
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.
◆
If an ingress packet matches an ACL specified by this command, any deny
rules included in the ACL will be ignored.
◆
If match criteria includes an IP ACL or IP priority rule, then a VLAN rule
cannot be included in the same class map.
◆
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.
◆
Up to 16 match entries can be included in a class map.
