Configuring Traffic Storm Control
Because of hardware limitations and the method by which packets of different sizes are counted, the level
percentage is an approximation. Depending on the sizes of the frames making up the incoming traffic,
the actual enforced level might differ from the configured level by several percentage points.
This example shows how to enable multicast traffic storm control on Gigabit Ethernet interface 3/16 and
how to configure the traffic storm control level at 70.5 percent:
Router# configure terminal
Router(config)# interface gigabitethernet 3/16
Router(config-if)# storm-control multicast level 70.5
Router(config-if)# end
This example shows how the traffic storm control level configured for one mode affects all other modes
that are already configured on the Gigabit Ethernet interface 4/10:
Router# show run inter gig4/10
