Storm control commands can be used 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.

unicast storm control thresholds

* Enabling hardware-level storm control with this command on a port will disable

software-level automatic storm control on the same port if configured by the

This command configures broadcast, multicast and unknown unicast storm

control. Use the no form to restore the default setting.

switchport {broadcast | multicast | unknown-unicast}

no switchport {broadcast | multicast | unknown-unicast}

broadcast - Specifies storm control for broadcast traffic.

multicast - Specifies storm control for multicast traffic.

unknown-unicast - Specifies storm control for unknown unicast

rate - Threshold level as a rate; i.e., kilobits per second (kbps).

(Range: 64-1000000 for Gigabit Ethernet ports)
