Description
Select the unit you wish to configure.
Use the drop-down menu to select the port range to use for this configuration.
Select the method of traffic control from the drop-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.
Shutdown – 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 Count Down 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 port recovers after 5 minutes automatically or the user manually
resets the port using the Port Settings window (System Configuration > Port
Configuration> Port Settings). Choosing this option obligates the user to configure
the Time Interval setting as well, which will provide packet count samplings from the
Switch's chip to determine if a Packet Storm is occurring.
