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.
