Usage Guidelines
During multicast packet processing or broadcast storms, certain packet 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 packet processors using an optional active
polling mechanism and configures a hardware recovery mechanism for a system with such a hung
state.
Example
The following command sets the a BlackDiamond switch to reset an I/O module with a processor in a
hang state:
