Shutdown, Countdown is disabled, and the Switch detects a storm, it directly shuts down the
port. The default is 0.
Time Interval (5-30) The Time Interval will set the time between Multicast and Broadcast packet counts sent from the
Switch's chip to the Traffic Control function. These packet counts are the determining factor in
deciding when incoming packets exceed the Threshold value. The Time Interval may be set
between 5 and 30 seconds, with a default setting of 5 seconds.
Threshold (512- Specifies the maximum number of kbit per second that will trigger the Traffic Control function to
1024000) commence. The configurable threshold range is from 512 to 1024000, with a default setting of
512 Kbps.
Storm Control Type Specifies the desired Storm Control Type: None, Broadcast, Multicast, Unknown Unicast,
Broadcast + Multicast, Broadcast + Unknown Unicast, Multicast + Unknown Unicast, and
Broadcast + Multicast + Unknown Unicast.

•
None – Will not send any Storm trap warning messages, regardless of the action taken
by the Traffic Control mechanism.
•
Storm Occurred – Will send Storm Trap warning messages upon the occurrence of a
Traffic Storm only.
•
Storm Cleared – Will send Storm Trap messages when a Traffic Storm has been
cleared by the Switch only.
•
Both – Will send Storm Trap messages when a Traffic Storm has been both detected
and cleared by the Switch.
NOTE: Traffic Control cannot be implemented on ports that are set for
Link Aggregation (Port Trunking).
NOTE: Ports that are in the Shutdown Forever mode will be seen as
Discarding in Spanning Tree windows and implementations though these
ports will still be forwarding BPDUs to the Switch's CPU.
NOTE: Ports that are in Shutdown Forever mode will be seen as link down
in all windows and screens until the user recovers these ports.
