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.
To configure the engine watchdog timer, do the following:
1. | From the device view, select GigaSMART > GigaSMART Groups > GigaSMART Groups. |
2. | If you are modifying an existing GigaSMART Group, select the GS Group and click Edit. Otherwise, click New. |
3. | In the Alias field, enter an alias for this GS Group. |
4. | In Port List field, select the engine port for this GS Group. |
