Manage the Storm Control Settings
A broadcast storm is the result of an excessive number of broadcast messages
simultaneously transmitted across a network by a single port. Forwarded message
responses can overload network resources and/or cause the network to time out.
The switch measures the incoming broadcast/multicast/unknown unicast packet rate per port
and discards packets when the rate exceeds the defined value. Storm control is enabled per
interface, by defining the packet type and the rate at which the packets are transmitted.
Configure Global Storm Control Settings
To configure global storm control settings:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
The login window opens.
3. Enter the user name and password.
The default admin user name is
admin and the default admin password is blank, that is,
do not enter a password.
4. Click the Login button.
The System Information page displays.
5. Select Security > T
raffic Control > Storm Control > Storm Control Global
Configuration.
The following three controls provide an easy way to enable or disable each type of
packets to be rate-limited on every port in a global fashion. The effective storm control
