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
map_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,
enter:
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
mode.
For example, to use the
class
class-default
command, enter:
host1/Admin(config-pmap)#
class class-default
host1/Admin(config-pmap-lb-c)#
insert-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.
