Provisioned Inactivity Timer

---

The Data Border Element (DBE) now has its own provisioned inactivity timer that alerts the DBE when the media gateway controller (MGC) fails, thereby improving high availability.

Information About the Provisioned Inactivity Timer

The DBE inactivity timer starts (resets) after the media gateway (MG) receives a successful response from the MGC to an initial request for ServiceChange (subsequent transaction). When an inactivity timer event occurs, the timer reports it to the MGC, using a NOTIFY event with a request ID of 0.

If required, you can override the default value of the provisioned inactivity timer on the DBE, and provision the MGC through the CLI, as before, to subscribe to the inactivity timer with a different duration. However, after cancellation of the MGC subscription, or if the association fails, the subscribed value is automatically deleted and the DBE-provisioned inactivity timer value again becomes active.

Configuring the Provisioned Inactivity Timer

The new command defines the duration of the provisioned inactivity timer.

SUMMARY STEPS

1. configure

2. sbc service-name

3. dbe

4. vdbe

5. h248-inactivity-duration duration

6. commit

7. exit

DETAILED STEPS

	Command or Action	Purpose
Step 1	configure Example: P/0/RP0/CPU0:router# configure	Enters configuration mode.
Step 2	sbc service-name Example: RP/0/RP0/CPU0:router(config)#sbc mysbc	Activates configuration mode for a particular SBC instance. Use the service-name argument to define the name of the service you want to configure.
Step 3	dbe Example: RP/0/RP0/CPU0:router(config-sbc)# dbe	Enters the submode of the data border element (DBE) function.
Step 4	vdbe Example: RP/0/RP0/CPU0:router(config-sbc-dbe)# vdbe	Enters the DBE submode of vdbe, in which to configure the inactivity timer.
Step 5	h248-inactivity-duration duration Example: RP/0/RP0/CPU0:router(config-sbc-dbe-vdbe)# h248-inactivity-duration 3000	Sets the time, during which the MGC can be inactive before an event is launched. •The duration argument defines this time in milliseconds in multiples of 10. The default is zero. The range is 0-655,350. In the example to the left, the command configures the vDBE to use a default timer duration of 30 s (set as 3000).
Step 6	commit Example: RP/0/RP0/CPU0:router(config-sbc-dbe-vdbe-h248- inactivity-duration))# commit	Saves configuration changes. Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session.
Step 7	exit Example: RP/0/RP0/CPU0:router(config-sbc-dbe-vdbe-h248- inactivity-duration)# exit	Exits the current mode of the configuration.
