Default
The default is log.
Usage Guidelines
During multicast packet processing or broadcast storms, certain processor chips in the switch that are
involved with QoS and packet scheduling can enter a hang state and cannot independently recover.
This command enables dynamic monitoring of these processors and configures a hardware recovery
mechanism for a system with such a hung processor.
NOTE
The system hardware recovery mechanism attempts to recover from a hung state that is due to
multicast or broadcast storms. This recovery mechanism does not provide recovery from a physical
hardware failure.
