Description: The broadcast falling threshold is measured in number of broadcast frames received on a port in a second.

When the falling threshold is crossed and the c2900PortBroadcastStormAction was stopBroadcastForwarding(1) then broadcast forwarding will be re-enabled on the port. For the other values of c2900PortBroadcastStormAction, crossing the falling threshold has no affect.

What is c2900PortBroadcastFallingThreshold?

A read-write value giving the broadcast frames-per-second rate that, once traffic drops below it, re-enables broadcast forwarding on a port that had been disabled due to a storm.
