Configuring storm control on SonicWall Switch

Description
Storm Control limits the amount of Broadcast, Unknown Multicast, and Unknown Unicast frames accepted and forwarded by the Switch. Storm Control can be enabled per port by defining the packet type and the rate that the packets are transmitted at.
A traffic storm is generated when messages are broadcast on a network and each message prompts a receiving node to respond by broadcasting its own messages on the network. This, in turn, prompts further responses, creating a snowball effect. The LAN is suddenly flooded with packets, creating unnecessary traffic that leads to poor network performance or even a complete loss of network service.
The Switch measures the incoming Broadcast, Unknown Multicast, and Unknown Unicast frames rates separately on each port, and discards the frames when the rate exceeds a user-defined rate.
To configure Storm Control for a port, navigate to Manage|Switch Controller and select the Port.
Storm Control Settings
- Broadcast: Enter the broadcast rate in kilobits per second. The Gigabit Ethernet ports have a maximum speed of 1000000 kilobits per second. If the rate of broadcast traffic ingress on the interface increases beyond the configured threshold, the traffic is dropped.
- Unknown Multicast: Enter the Unknown Multicast rate in kilobits per second. The Gigabit Ethernet ports have a maximum speed of 1000000 kilobits per second. If the rate of multicast traffic ingress on the interface increases beyond the configured threshold, the traffic is dropped.
- Unknown Unicast: Enter the Unknown Unicast rate in kilobits per second. The Gigabit Ethernet ports have a maximum speed of 1000000 kilobits per second. If the rate of unicast traffic ingress on the interface increases beyond the configured threshold, the traffic is dropped.
TIP: If the Value is set to 0 then it is set to disabled. Rate must be multiple of 16 Range: 0 - 10000000.
