Overview Use this command to specify the speed limiting level for broadcast, multicast, or dlf

traffic type to the specified percentage of the maximum port speed.
Use the no variant of this command to disable storm-control for broadcast,
multicast or dlf traffic.
Syntax
storm-control {broadcast|multicast|dlf} level <level>
no storm-control {broadcast|multicast|dlf} level
Default Disabled
Mode Interface Configuration
Usage notes Flooding techniques are used to block the forwarding of unnecessary flooded
traffic. A packet storm occurs when a large number of broadcast packets are
received on a port. Forwarding these packets can cause the network to slow down
or time out.
More than one limit type can be set at a time. For example, you can configure both
broadcast and multicast levels on the same port, at the same time.
Example To limit broadcast traffic on port1.0.2 to 30% of the maximum port speed, use the
following commands:
awplus# configure terminal
awplus(config)# interface port1.0.2
awplus(config-if)# storm-control broadcast level 30
