Configure Storm Control
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, cause the network to time out, or do both.
The switch measures the incoming packet rate per port for broadcast, multicast, unknown,
and unicast packets and discards packets if the rate exceeds the defined value. You enable
storm control per interface, by defining the packet type and the rate at which the packets are
transmitted.
Storm control is configured as a percentage of the maximum port speed.
To configure storm control settings:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the Switch on page 14.
