E2 CLF Configurable Timeout

You can configure a transaction timer value for each external policy server based on the round-trip and response times for each specific policy server. Defining this transaction timer value allows you to avoid situations when policy/DIAMETER servers fail to respond to the Oracle Communications Session Border Controller ’s requests, ensuring that transactions proceed in the desired amount of time and avoiding undesirable delays in set-up times.

The time you set for the DIAMETER CLF must be from 1 second to 15 seconds. For purposes of backward compatibility, 15 seconds is the default. It is recommended that you set the timer at 6 seconds or greater in accordance with the smallest DIAMETER Watchdog Request/Answer (DWR/DWA) per RFC 3588.

Activating a Configuration with the E2 CLF Timeout Defined

When you define a value for the E2 CLF timeout and activate your configuration, the change in time will only affect new client transactions. Previously existing client transactions will use the value in effect prior to your having activated the configuration.

E2 CLF Timeout Configuration

To define the E2 CLF timeout for an external policy server:

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal
   ORACLE(configure)#

2. Type media-manager and press Enter.

   ORACLE(configure)# media-manager
   ORACLE(media-manager)#

3. Type ext-policy-server and press Enter.

   ORACLE(media-manager)# ext-policy-server
   ORACLE(ext-policy-server)#

4. trans-expires—Enter the time (in seconds) for the E2 CLF timeout, a transaction timer value for each external policy server based on the round-trip and response times for each specific policy server. The default for this parameter is 15 seconds; your entry must be between 1 and 15.
5. Save your work.
