Class Maps
	 
  
		The port-based rate limit, applied with
			the default class map, is applicable to all traffic and can be used for ingress and
			egress service policies. Port-based policing is only implemented to match any
			criteria.
		You can use an IP standard or extended ACL to classify traffic for ingress-only service
			policies. You can use an ACL for match criteria.
		Follow these rules when configuring class
			maps: 
				- A class map name must be unique among
					all maps of this type. 
- A class map name must begin with an
					alphabetic character (a-z or A-Z). An underscore, a hyphen, and the numeric
					values 0-9 can be used in the body of the name but not as the first character. 
- You cannot delete a class map that is
					referenced in a policy map. 
- You cannot delete a class map when the policy map
					is bound to an active service policy. 
- You can configure a maximum of
					32,000 class maps. 
- You can combine the default and match
					access-group class maps in one policy map. 
- You can specify only one default class
					map per policy map.
