Chapter 4 Avaya P460 Layer 2 Features
Broadcast Storm Control
Broadcast Storm Control Overview
This feature allows you to protect the network or switch from excessive Broadcast
or Unknown traffic.
When the Broadcast Storm Control is enabled, the switch discards broadcast,
multicast and unknown packets when the Broadcast Threshold Rate on a switch
port exceeds a specified threshold. The Broadcast Threshold Rate is the number of
broadcast packets received by a port per second.
When you enable Broadcast Storm Control, counters are set on all 10/100 Mbps
ingress ports.
L Broadcast Storm Control is only supported on 10/100 Mbps I/O ports.
The P460 hardware includes separate counters for broadcast, multicast and
unknown packets. When any of these counters crosses the specified threshold, the
respective storm packets are dropped.
