Configuring Broadcast Suppression

Purpose

To review and set the broadcast suppression threshold for one or more ports. This feature limits
the number of received broadcast frames the switch will accept per port. Broadcast suppression
thresholds apply only to broadcast traffic—multicast traffic is not affected. By default, a broadcast
suppression threshold of 14881 packets per second (pps) will be used, regardless of actual port
speed. Broadcast suppression protects against broadcast storms and ARP sweeps.
