Configuring 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:
-
Log in into Policy Builder.
-
Select Reference Data tab.
-
From the left pane, select Systems.
-
Select and expand your system name.
-
Select PCF Configuration.
-
In the right pane, configure the following parameters depending on the interface:
Parameter
Description
N7 Stale Session Timer in Minutes
The stale session does not map to a session that is alive or active. When the configured timer expires, the N7 sessions that are old or stale are deleted.
Default value is 180 minutes.
N15 Stale Session Timer in Minutes
When the configured timer expires, the N15 sessions that are old or stale are deleted.
Default value is 180 minutes.
Preferred Bit Rate
