Chapter 4 Configuring Class Maps and Policy Maps
Configuring a Layer 7 Policy Map
To manually insert a class map ahead of a previously specified class map, use the
class command with the insert-before keyword. Note that the ACE does not save
this sequence reordering as part of the configuration.
The syntax of the class command with the insert-
before keyword is:
class m
ap_name1 insert-before map_name2
When you use this command, the ACE places the current
class map (as specified
by the map_name1 argument) ahead of an existing class map (as specified by the
map_name2 argument).
For example, to define the sequential order of two class maps in the policy map,
ente
r:
host1/Admin(config-pmap-lb-c)# class L7_HTTP_SLB_CLASS insert-before
L7_SLB_SERVER_CLASS
To specify the class-default class map for the traffic policy, use the class
class-default command in policy map configuration mode. All traffic that fails to
meet the other matching criteria in the named class map belongs to the default
traffic class. If none of the specified classifications match, the ACE then matches
the action specified under the class class-default command. The class-default
class map has an implicit match any statement in it and is used to match any traffic
classification.
When you use this command, you will access policy map class configuration
mo
de.
For example, to use the class cl
ass-default command, enter:
host1/Admin(config-pmap)# class class-default
host1/Admin(config-pmap-lb-c)# in
sert-http Host
Specifying Layer 7 Policy Actions
To specify the policy map actions that you want applied to the Layer 7 policy map,
see the appropriate ACE document and chapter as outlined in Table 4-10.
Table 4-10 defines the associated actions
for the different Layer 7 application
policies based on the function of the Layer 7 policy map.
