Setting the Maximum Number of Broadcast Frames
To set the maximum number of broadcast frames you want the ports on
the switch to forward, perform the following procedure:
1. From the Home page, select Configuration.
2. From the Configuration page, select Layer 1.
When you open the Layer 1 page, the Port Settings tab is selected
by default. If it is not selected, select it now.
3. In the graphical switch image, click a port where you want to specify
the maximum number of broadcast frames.
The selected port turns white. To deselect a port, click it again. You
can select only one port at a time.
4. Click Modify.
The current settings for the port are displayed in the Port
Configuration window.
5. In the Broadcast Storm Control section of the window, enter the
maximum number of broadcast packets you want the port to accept.
The range is 0 to 1023 broadcast frames. Specifying a value of “0”
disables broadcast frame control on the port. The port will accept
all broadcast frames.
As an example, assume that you enter a value of 300 as the
maximum number of broadcast frames for a port. Also assume
that the port is operating at 100 Mbps and that you specified an
interval timer of 100 milliseconds for 100 Mbps ports. The result
would be that the port would accept up to 300 broadcast frames
every 100 milliseconds. If it received more than 300 broadcast
frames during a 100 millisecond period, the extra broadcast
frames would be discarded by the port and would not be
forwarded by the switch.
6. Click Apply.
7. Repeat this procedure to set the maximum number of broadcast
frames for other ports on the switch.
