Deleting a PCEF Profile

These procedures show how to enter maintenance mode to halt new sessions from being started and verify that no sessions remain on the TDF domain or gateway before removing a policy and charging enforcement function (PCEF) profile from the TDF domain or service-selection profile configurations.

Note:

Regardless of whether a PCEF profile is associated within a TDF domain or not, or whether a PCEF profile is associated with a TDF domain-selection term or not, configuration changes and deletion of a PCEF profile (and other referenced objects of the profile) require that the TDF gateway be placed in maintenance mode. However, you need not activate maintenance mode for the gateway if you are adding a new PCEF profile.

Deleting a PCEF Profile with the TDF Domain in Maintenance Mode

This procedure shows how to enter maintenance mode to halt new sessions from being started and to verify that there are no sessions remaining on the TDF domain before removing a PCEF profile configuration that a TDF domain or service-selection profile references.

To activate maintenance mode for the TDF domain and make changes to a PCEF profile:

From configuration mode, activate maintenance mode for the TDF domain that references the PCEF profile.

Verify that the TDF domain is in maintenance mode.
The service mode for the TDF domain shows Maintenance—Active Phase if all the sessions using this TDF domain are cleared. The service mode for the TDF domain shows Maintenance—In Phase if some sessions are actively using this TDF domain.

Verify that no subscribers are active on the TDF domain.

(Optional) Terminate any remaining sessions on the TDF domain.

Verify that the TDF domain is in an active phase.

In the TDF domain or service-selection profile configuration, remove the referenced PCEF profile and commit the changes.

Verify that the changes were properly committed by showing the configuration for the entire TDF domain or service-selection profile to make sure the PCEF profile is deleted.

To view a PCEF profile configuration:

To view a PCC rulebase configuration:

To view a PCC rules configuration:

To view a flow description configuration:

To view a PCC action profile configuration:

(Optional) If the PCEF profile is not used in other TDF domain or service-selection profile configurations, you can delete the PCEF profile configuration and commit the changes.

Exit maintenance mode.

Return the gateway to operational state.

Deleting a PCEF Profile with the Gateway in Maintenance Mode

This procedure shows how to enter maintenance mode to halt new sessions from being started and to verify that no sessions remain on the TDF gateway before deleting PCEF profiles that are referenced by one or more TDF domains on a gateway.

To activate maintenance mode for the gateway and make changes to a PCEF profile:

From configuration mode, activate maintenance mode for the gateway.

Verify that the TDF gateway is in maintenance mode.
From the gateway hierarchy, the service mode shows Maintenance—Active Phase if all the sessions are cleared. The service mode shows Maintenance—In Phase if some sessions are active. The service mode shows Maintenance—Out Phase if maintenance mode is not configured, and the gateway is in operational mode.

Verify that no subscribers are active on the gateway.

(Optional) Terminate any remaining sessions on the gateway.

Verify that the gateway is in an active phase.

For each applicable TDF domain, delete the PCEF profile from the TDF domain configuration and commit the changes.

Verify that the changes were properly committed by showing the configuration for each TDF domain to make sure the PCEF profile is deleted.
