Policy Map Class Configuration Mode Commands
To configure a service policy in an optimization policy map, use the class policy map configuration command. To unconfigure settings, use the no form of this command.
class classmap-name [ insert-before [ existing_class ]]
no class classmap-name [ insert-before [ existing_class ]]

Usage Guidelines
Use the class command to add or modify a service policy (policy rule) for traffic identified by a class map. This command invokes the Policy Map Class configuration mode, which is indicated by a different prompt (config-pmap-c). To return to global configuration mode, enter the exit command.
You can delete a policy rule by using the no form of this command.
The WAAS software comes with many class maps and policy rules that help your WAAS system classify and optimize some of the most common traffic on your network. Before you create a new class map or policy rule, we recommend that you review the default class map and policy rules and modify them as appropriate. It is usually easier to modify an existing class map or policy rule than to create a new one. For a list of the default applications, class maps, and policy rules, see the Cisco Wide Area Application Services Configuration Guide.
Note
We strongly recommend that you use the WAAS Central Manager GUI to centrally configure policy maps for your WAAS devices. For more information, see the Cisco Wide Area Application Services Configuration Guide.
Examples
The following example shows how to configure a policy rule in an optimization policy map:

(config-pmap-c) optimize
To configure optimization actions in a WAAS optimization policy, use the optimize policy class map configuration command. To unconfigure optimization actions, use the no form of this command.
optimize { tfo-only | {[ DRE { bidirectional | adaptive | unidirectional }] [ LZ ] | full } [ accelerate { cifs | http | ica | mapi | MS-port-mapper | ssl | video }] [ application app-name ]
no optimize { tfo-only | {[ DRE { bidirectional | adaptive | unidirectional }] [ LZ ] | full } [ accelerate { cifs | http | ica | mapi | MS-port-mapper | ssl | video }] [ application app-name ]

Usage Guidelines
This command configures the optimization actions in a WAAS optimization policy.
You may specify only a single optimize or pass-through action for a particular class. If one of these actions is already present and you specify a new action, the new action replaces the existing action. If neither of these actions is specified, the default is pass-through.
The following DRE caching modes are supported:
- Bidirectional—The peer WAEs maintain identical caches for inbound and outbound traffic. This caching mode is best suited where a significant portion of the traffic seen in one direction between the peers is also seen in the reverse direction.
- Unidirectional—The peer WAEs maintain different caches for inbound and outbound traffic. This caching mode is best suited where a significant portion of the traffic seen in one direction between the peers is not seen in the reverse direction.
- Adaptive—The peer WAEs negotiate either bidirectional or unidirectional caching based on the characteristics of the traffic seen between the peers.
Examples
The following example shows how to configure the optimization action in a policy:

(config-pmap-c) pass-through
To configure the pass-through action in an optimization policy rule, use the pass-through policy class map configuration command. To unconfigure the pass-through action, use the no form of this command.
pass-through [ application app-name ]
no pass-through [ application app-name ]
Syntax Description
(Optional) Assign the specified application identifier to connections matching the class for statistics collection. Available only for WAAS optimization class maps. |
Defaults
Command Modes
Policy map class configuration
Device Modes
Usage Guidelines
In an optimization policy, this command prevents the traffic in the class from being optimized and instead the traffic is passed through unoptimized. You can optionally specify an application name with which to associate the traffic in the class for statistics collection purposes.
You may specify only a single optimize or pass-through action for a particular class. If one of these actions is already present and you specify a new action, the new action replaces the existing action. If neither of these actions is specified, the default is pass-through.
In an AppNav policy rule, this command prevents the traffic in the class from being distributed to WAAS nodes and instead the traffic is passed through unoptimized.
This command is useful in a nested policy to override a distribute action specified in the parent policy.
If you specify the pass-through action in a policy, any distribute or monitor-load actions are removed.
Examples
The following example shows how to configure the pass-through action in an optimization policy:

(config-pmap-c) set ip dscp
To configure the DSCP marking in a WAAS optimization policy, use the set ip dscp policy class map configuration command. To unconfigure DSCP marking, use the no form of this command.
Syntax Description
Assign the specified DSCP marking value ( Table 3-2 ) to the connections in the class. |
Defaults
Command Modes
Policy map class configuration
Device Modes
Usage Guidelines
This command overrides the global default DSCP marking value, which is set to copy by default.
If you do not specify the set ip dscp command, the class uses the global default DSCP marking, which is set by the service-policy type waas set ip dscp command.
You can specify the set ip dscp command only when the optimize action has been configured for a class.
Examples
The following example shows how to configure the DSCP marking value for connections in the class:
