# Traffic Policy-Map Configuration Mode Commands

A Policy-Map imposes a flow-based traffic policy for Traffic Policy feature within a destination context. It designates the flow treatment based on the classification rules configured in Class-Map mode for a subscriber session flow.

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

accounting suppress

Suppresses accounting action for traffic flows matching the policy map.

Product:

ASN GW, HA, HSGW, PDSN, P-GW, SAEGW, SCM
Privilege:

Syntax

[ no ] accounting suppress
no

Removes the suppression of accounting for traffic flow matching this policy map.
Usage:

Use this command to suppress accounting action on traffic flow matching this policy map.

Policy maps configured for accounting suppression are used to implement the QChat Billing Suppression feature that selectively starts and terminates accounting sessions based on the categorization of traffic as being interesting or non-interesting. See the accounting trigger command.
Example:
The following command configures suppression of accounting on traffic flows matching this policy map:

    accounting suppress

accounting trigger

Configures an accounting trigger policy map to selectively start and terminate accounting sessions based on the categorization of traffic as being interesting or non-interesting. This command supports the QCHAT Billing Suppression feature.
Platform:

ASR 5000

Product:

HSGW, PDSN, P-GW, SAEGW, SCM
Privilege:

Security Administrator, Administrator
Syntax

    [ no | default ] accounting
    trigger { inactivity-timeout | interesting-traffic | intra-service-handoff }

default

Sets or restores the default value assigned for specified parameter.
no

Disables previously configured triggers.
inactivity-timeout

Generates an accounting Stop message if there has been no data activity on the session for the interim accounting timeout interval.

Default: disabled
interesting-traffic

Generates an accounting Start message upon arrival of interesting traffic.

Default: disabled
intra-service-handoff

Generates accounting Start and Stop messages during intra-service handoffs.

Default: enabled

If disabled, the messages are suppressed during the handoffs. The current accounting session continues and no Stop or Start messages are generated during the intra-service handoff.
Usage:

Use this command to configure an accounting trigger policy map (ATPM) to selectively start and terminate accounting sessions based on the categorization of traffic as being interesting or non-interesting. This command supports the QChat Billing Suppression feature.

Interesting traffic is identified as traffic that does not match any of the other Accounting Policy Maps (APMs) configured for accounting suppression. See the accounting suppress command.

An ATPM is similar to an APM, but without the class map rules. The ATPM is configured as of type accounting using the type accounting command.

Optionally, timeout can be triggered when there is no data traffic for the interim accounting timeout interval using the accounting trigger inactivity-timeout stop command. On timeout, the accounting session is terminated and an Accounting Stop message is sent. A new accounting session is created if interesting traffic resumes.

In the ATPM, the trigger to start accounting for interesting traffic is configured using the accounting trigger interesting-traffic command. Accounting Start is triggered on arrival of interesting traffic, or change in airlink parameters conveyed through active-start airlink record. If an active-start record was included in the initial connection setup, Accounting Start is not triggered. But if the active-start comes separately and is the first one for the session, it is treated as airlink change and an Accounting Start is sent.

The ATPM should have the lowest precedence among the APMs.

As the airlink events are generated on the ingress side, the ATPM must be included in a policy group that is applied to the ingress direction in the subscriber profile. The configuration is applicable only for standard trigger policy and session based accounting mode.
Example:
The following command sets the trigger to generate accounting start message upon arrival of interesting traffic:

    accounting trigger
    interesting-traffic
