c2900PortBroadcastFallingThreshold
CISCO-C2900-MIB ·
.1.3.6.1.4.1.9.9.87.1.4.1.1.21
Object
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.
