Use the Traffic > Storm Control page to configure broadcast, multicast, and unknown unicast storm control thresholds. Traffic storms may occur when a device on your network is malfunctioning, or if application programs are not well designed or properly configured. If there is too much traffic on your network, performance can be severely degraded or everything can come to complete halt.
You can protect your network from traffic storms by setting a threshold for broadcast, multicast or unknown unicast traffic. Any packets exceeding the specified threshold will then be dropped.
Command Usage
Broadcast Storm Control is disabled by default.
Broadcast control does not effect IP multicast traffic.
When traffic exceeds the threshold specified for broadcast and multicast or unknown unicast traffic, packets exceeding the threshold are dropped until the rate falls back down beneath the threshold.
The rate limits set by this function are also used by automatic storm control when the control response is set to rate limiting by the "auto-traffic-control action" command.
Command Parameters
Displays a list of ports or trunks.
Indicates the port type. (1000BASE-T, 1000BASE SFP, or 10GBASE SFP+)
Specifies storm control for unknown unicast traffic.
Specifies storm control for multicast traffic.
Specifies storm control for broadcast traffic.
Enables or disables storm control. (Default: Disabled)
Threshold level in packets per second. (Range: 500-262142 pps; Default: 500 pps)
Indicates the resolution at which the rate can be configured.
