Command Mode

User Guidelines
Use the match protocol none command to remove any match condition for
Ethertype or Protocol number. Only one Ethertype match protocol statement
can appear in a class-map. Entering a match protocol statement overrides any
prior protocol match.
Prior to entering a match access-group command other than type IPv4 in
class-map configuration mode, it is necessary to enter the corresponding
match protocol command. For example, to match an IPv6 access-group, issue
the match protocol ipv6 command first. Use match protocol none to match a
MAC access-group. Only a single match protocol command may be issued.
If an ACL is referenced in the class-map, it must be of the same type as the
configured Ethertype.
If the match ethertype command is configured, match protocol may not be
configured, and vice versa.
