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.
NOTE: The minimum granularity of storm control on a GE port is 1pps.
The possible time settings for this field are 0 and 3 to 30 minutes. Tick the Disabled
check box, and the port will be shut down immediately when detecting storm.
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 600 seconds, with a default
setting of 5 seconds.
Specifies the maximum number of packets per second that will trigger the Traffic
Control function to commence. The configurable threshold range is from 0-255000
with a default setting of 131072 packets per second.
Specifies the desired Storm Control Type: None, Broadcast, Multicast, Unknown
Unicast, Broadcast + Multicast, Broadcast + Unknown Unicast, Multicast + Unknown
Unicast, and Broadcast + Multicast + Unknown Unicast.
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)
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.
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.
