Insight Managed 8-Port Gigabit Ethernet Smart Cloud Switch with 2 SFP Fiber Ports
 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 13.
The login window opens.
4. Enter the switch’s password in the password field.
The default password is password. If you added the switch to a network on the Insight
app before and you did not yet change the password through the local browser interface,
enter your Insight network password.
The System Information page displays.
5. Select Security > Traffic Control > Storm Control.
The Storm Control page displays.
6. In the Storm Control section, from the Ingress Control Mode menu, select the mode of
broadcast affected by storm control:
• Disabled. Storm control is disabled. This is the default setting.
• Unknown Unicast. If the rate of incoming unknown Layer 2 unicast traffic (that is,
traffic for which a destination lookup failure occurs) increases beyond the configured
threshold on an interface, the traffic is dropped.
• Multicast. If the rate of incoming Layer 2 multicast traffic increases beyond the
configured threshold on an interface, the traffic is dropped.
• Broadcast. If the rate of incoming Layer 2 broadcast traffic increases beyond the
configured threshold on an interface, the traffic is dropped.
7. In the Storm Control section, if the selection from the Ingress Control Mode menu is not
Disabled, specify whether the ingress control mode is enabled by selecting Enable or
Disable from the Status menu.
8. In the Storm Control section, in the Threshold field, specify the maximum rate at which
unknown packets are forwarded.
The range is a percent of the total threshold between 0–100%. The default is 5%.
9. In the Storm Control section, from the Control Action mode menu, select one of the
following options:
• None. This is the default setting.
• Trap. If the threshold of the configured broadcast storm is exceeded, a trap is sent.
• Shutdown. If the threshold of the configured broadcast storm is exceeded, the port is
shut down.
10. Click the Apply button.
