Traffic Trap
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 in the Action field.

From…To | Select the ports of this Switch to configure for Storm Control. |
|
|
Broadcast | Enables or disable Broadcast Storm Control. |
Storm |
|
Multicast Strom | Enables or disables Multicast Storm Control. |
|
|
Unicast Storm | Enables or disables Unknown Unicast storm control. |
|
|
Threshold | Specifies the number of broadcast/multicast/unicast packets, in Kbps (Kilo bit per seconds), received |
| by the Switch that will trigger the Traffic Control function to commence. The configurable threshold |
| range is from |
|
|
Action | Select the method of traffic Control from the pull down menu. The choices are: |
| Drop – Utilizes the hardware Traffic Control mechanism, which means the Switch’s hardware will |
| determine the Packet Storm based on the Threshold value stated and drop packets until the issue is |
| resolved. |
| Shut Down – Utilizes the Switch’s software Traffic Control mechanism to determine the Packet Storm |
| occurring. Once detected, the port will deny all incoming traffic to the port except STP BPDU packets, |
| which are essential in keeping the Spanning Tree operational on the Switch. If the Countdown timer |
| has expired and yet the Packet Storm continues, the port will be placed in Shutdown Forever mode |
| and is no longer operational until the user manually resets the port using the Storm Control Recover |
| setting at the top of this window. Choosing this option obligates the user to configure the Interval |
| setting as well, which will provide packet count samplings from the Switch’s chip to determine if a |
| Packet Storm is occurring. |
Count Down | The Count Down timer is set to determine the amount of time, in minutes, that the Switch will wait |
| before shutting down the port that is experiencing a traffic storm. This parameter is only useful for |
| ports configured as Shutdown in their Action field and therefore will not operate for Hardware based |
| Traffic Control implementations. The possible time settings for this field are 0, |
| default setting for this field and 0 will denote that the port will never shutdown. |
|
|
Interval | The 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 Interval may be set between 5 and 30 seconds |
| with the default setting of 5 seconds. |
