configuration mode. Then use the match command (page 4-194) to specify
the criteria for ingress traffic that will be classified under this class map.
• Up to 16 match commands are permitted per class map.
• The class map is used with a policy map (page 4-195) to create a service
policy (page 4-199) for a specific interface that defines packet classification,
service tagging, and bandwidth policing.
