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.
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 countdown timer
has expired and yet the Packet Storm continues, the port will be placed in rest mode and if no action
is taken will enter auto-recovery mode after a five minute period. 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 (0 or 5-30):
The countdown 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, 5-30 minutes. 0 denotes
that the port will never shutdown.
Time Interval (5-30):
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.
Shutdown Threshold (0-255000):
Specify the shutdown threshold for traffic threshold.
Storm Control Type:
User can select the
different Storm type from Broadcast, Multicast, Broadcast +
Multicast, Unknown Unicast, Bro Unknown Unicast, Mul Unknown Unicast, and Bro
Mul Unknown Unicast.

NOTE:
Traffic Control cannot be implemented on
ports that are set for Link Aggregation.
NOTE:
Ports that are in the rest 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 rest mode will be seen as
link down in all windows and screens until it
enters the auto-recovery mode or the user
recovers these ports by configuring the port state.
QoS > Bandwidth Control
The Bandwidth Control page allows network managers to define the bandwidth settings for a specified port’s
transmitting and receiving data rates.
