Engine Watchdog Timer in GigaSMART

In rare scenarios, a packet processing core in the CPU of a GigaSMART engine can enter a deadlocked state. The engine watchdog timer detects the issue and reloads the GigaSMART engine after a specified number of seconds. The engine watchdog timer is enabled by default with a value of 60 seconds. The maximum number of seconds is 600 seconds.

Note:  If a core is in a deadlocked state, all packets are dropped.

To access GigaSMART within GigaVUE-FM, access a device that has been added to GigaVUE-FM from the GigaVUE-FM interface. GigaSMART appears in the navigation pane of the device view on supported devices. Refer to Access GigaSMART from GigaVUE-FM for details.
