Creating a Layer 7 Policy Map

OL-11157-01
You associate the Layer 7 policy map within the appropriate Layer 3 and Layer 4
policy map to provide an entry point for the traffic classification. Layer 7 policy
maps are considered to be child policies and can only be associated within a Layer
3 and Layer 4 policy map. Only a Layer 3 and Layer 4 policy map can be activated
on a VLAN interface; a Layer 7 policy map cannot be directly applied on an
interface.
For more information about the role of policy maps in the ACE, see the
Map and Policy Map Overview"
This section describes how to configure a Layer 7 traffic policy and contains the
following topics:
Creating a Layer 7 Policy Map
•
Adding a Layer 7 Policy Map Description
•
Including Inline Match Statements in a Layer 7 Policy Map
•
• Specifying a Layer 7 Traffic Class with the Traffic Policy
Specifying Layer 7 Policy Actions
•
Associating the Layer 7 Policy Map with a Layer 3 and Layer 4 Policy Map
•
To specify the type of Layer 7 traffic policy map, use the policy-map type
command in configuration mode. The syntax of this command is:
policy-map type {loadbalance first-match | inspect http all-match |
inspect ftp first-match | optimization http first-match} map_name
The keywords and arguments are:
loadbalance first-match—Defines Layer 7 server load-balancing decisions.
•
You will enter policy map load balancing configuration mode. The ACE
executes the specified action only for traffic that meets the first matching
load-balancing classification with a policy map. The ACE does not execute
any additional actions.
• inspect http all-match—Defines the deep inspection of HTTP traffic. You
will enter policy map HTTP inspection configuration mode. The ACE
attempts to match a packet against all classes in the policy map and executes
the actions of all matching classes associated with the policy map.
