Stale Sessions Cleanup

In the CDL sessions, PCF adds the unique session key SupiDnnKey and the pre-existing unique keys that include FramedIpv6PrefixKey. With the CDL's index overwrite detection command in the PCF Ops Center, the administrators can configure the ability to delete the old session using the same unique key while the new session is created.

The unique keys that should be used in the overwrite detection configuration are SupiDnnKey and FramedIpv6PrefixKey with the action as delete_record.

Note

If two unique keys (one key mapped to the notify action and the other to the delete action) point to the same primary key, then only the notify action is considered for the primary key.
