Chapter12 Configuring Port-Based Traffic Control
Configuring Storm Control
To disable storm control, use the no storm-control broadcast level, no storm-control multicast level,
or no storm-control unicast level interface configuration commands.
This example shows how to set the multicast storm control level at 70.5 percent on Fast Ethernet
interface 17 and verify the configuration:
Switch# configure terminal
Switch(config)# interface fastethernet0/17
Switch(config-if)# storm-control multicast level 70.5
Switch(config-if)# end
Switch# show storm-control fastethernet0/17 multicast
Interface Filter State Level Current
--------- ------------- ------- -------
Fa0/17 Forwarding 70.50% 0.00%
Disabling Storm Control
Beginning in privileged EXEC mode, follow these steps to disable storm control on an interface:
This example shows how to disable the multicast storm control on Fast E thernet interface 17 and verify
the configuration:
Switch# configure terminal
Switch(config)# interface fastethernet0/17
Switch(config-if)# no storm-control multicast level
Switch(config-if)# end
Switch# show storm-control fastethernet0/17 multicast
Interface Filter State Level Current
--------- ------------- ------- -------

Step7 show storm-control [interface-id] [broadcast |
multicast | unicast] Verify the storm control suppression levels set on the interface for
the specified traffic type. If you do not enter a traffic type,
broadcast storm control settings are displayed.
Step8 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface interface-id Enter interface configuration mode, and enter the type and number of
the physical interface to configure, for example GigabitEthernet0/1.
Step3 no storm-control broadcast level Disable broadcast storm control on the i nterfa ce.
Step4 no storm-control multicast level Disable multicast storm control on the interface.
Step5 no storm-control unicast level Disable unicast storm control on the interface.
Step6 end Return to privileged EXEC mode.
Step7 show storm-control [interface-id]
[broadcast | multicast | unicast] Verify that there are no storm control suppression levels set on the
interface for the specified traffic type. If you do not enter a traffic
type, broadcast storm control settings are displayed.
Step8 copy running-config startup-config (Optional) Save your entries in the configuration file.
