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.
