Traffic Control Type Specify the desired Storm Control Type: None, Broadcast, Multicast, Unicast,
Broadcast + Multicast, Broadcast + Unicast, Multicast + Unicast, and Broadcast +
Broadcast (0-1488100)
Enter the number of broadcast packets per second received by the Switch that will
trigger the storm traffic control measure.
Multicast (0-1488100)
Enter the number of multicast packets per second received by the Switch that will
trigger the storm traffic control measure.
Unicast (0-1488100)
Enter the number of unicast packets per second received by the Switch that will
trigger the storm traffic control measure.
Traffic Trap Settings
Enable sending of Storm Trap messages when the type of action taken by the
Traffic Control function in handling a Traffic Storm is one of the following:
None – Will send no Storm trap warning messages regardless of 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.
This function cannot be implemented in the hardware mode. (When Drop is chosen
for the Action parameter)
Traffic Log Settings
Use the drop-down menu to enable or disable the function. If enabled, the traffic
control states are logged when a storm occurs and when a storm is cleared. If the
log state is disabled, the traffic control events are not logged.
Traffic Auto Recover
Time (0-65535)
Enter the time allowed for auto recovery from shutdown for a port. The default value
is 0, which means there is no auto recovery and the port remains in shutdown
forever mode. This requires manual entry of the CLI command config ports
[ <portlist> | all ] state enable to return the port to a forwarding state.
Click the Apply button to accept the changes made for each individual section.
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
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.
NOTE: The minimum granularity of storm control on a GE port is 1pps.
