Configuring the Stale Session Timer

This section describes how to configure the stale session timer.

Stale session builds up due to network issues, timeout, and so on. As a result, PCF starts rejecting new sessions due to capacity or session license limit. The stale session timer configuration lets you set a timer after which sessions that are stale are purged.

To configure the stale session timer for N7 and N15, use the following configuration:

  1. Log in into Policy Builder.

  2. Select Reference Data tab.

  3. From the left pane, select Systems.

  4. Select and expand your system name.

  5. Select PCF Configuration.

  6. In the right pane, configure the following parameters depending on the interface:

    Parameter

    N7 Stale Session Timer in Minutes
