This command configures broadcast, multicast and unknown unicast storm
control. Use the no form to restore the default setting.

switchport { broadcast | multicast | unicast } packet-rate rate
no switchport { broadcast | multicast | unicast }
broadcast - Specifies storm control for broadcast traffic.
multicast - Specifies storm control for multicast traffic.
unicast - Specifies storm control for unknown unicast traffic.
rate - Threshold level as a rate; i.e., kilobits per second.

◆
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.
◆
Traffic storms can be controlled at the hardware level using this
command or at the software level using the auto-traffic-control
command. However, only one of these control types can be applied to a
port. Enabling hardware-level storm control on a port will disable
automatic storm control on that port.
