Chapter 9 Configuring Port-Based Traffic Control
Configuring Protected Ports
To disable storm control, use the no storm-control {broadcast | multicast | unicast} level interface
configuration command.
EXAMPLE
This example shows how to enable unicast storm control on a port with an 87-percent rising suppression
level and a 65-percent falling suppression level:
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# storm-control unicast level 87 65
This example shows how to enable broadcast address storm control on a port to a level of 20 percent.
When the broadcast traffic exceeds the configured level of 20 percent of the total available bandwidth of
the port within the traffic-storm-control interval, the switch drops all broadcast traffic until the end of
the traffic-storm-control interval:
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# storm-control broadcast level 20
Configuring Protected Ports
You can configure protected ports on a physical interface that is configured as an NNI (for example,
Gigabit Ethernet port 1) or an EtherChannel group (for example, port-channel 5). When you enable
protected ports for a port channel, it is enabled for all ports in the port-channel group.
BEFORE YOU BEGIN
Review the “Guidelines and Limitations” section on page 9-5.
DETAILED STEPS
Step 7
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.
Step 8
copy running-config
startup-config
(Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the interface to configure, and enter interface
configuration mode. The interface must be an NNI.
Note By default, UNIs and ENIs are protected ports.
Step 3
switchport protected Configure the interface to be a protected port.
Step 4
end Return to privileged EXEC mode.
