Chapter 9 Configuring Port-Based Traffic Control
Verifying Configuration
Verifying Configuration
The show interfaces interface-id switchport privileged EXEC command displays (among other
characteristics) the interface traffic suppression and control configuration. The show storm-control and
show port-security privileged EXEC commands display those storm control and port security settings.
Configuration 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
This example shows how to configure a port as a protected port:
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# switchport protected
Switch(config-if)# end
This example shows how to configure a FastEthernet port as a protected port:
Switch# configure terminal
Switch(config)# interface fastethernet 0/1
Switch(config-if)# port-type NNI
Command Purpose
show interfaces [interface-id] switchport Displays the administrative and operational status of all switching
(nonrouting) ports or the specified port, including port blocking and
port protection settings.
show storm-control [interface-id] [broadcast |
multicast | unicast]
Displays storm control suppression levels set on all interfaces or the
specified interface for the specified traffic type or for broadcast traffic
if no traffic type is entered.
show port-security [interface interface-id] Displays port security settings for the switch or for the specified
interface, including the maximum allowed number of secure MAC
addresses for each interface, the number of secure MAC addresses on
the interface, the number of security violations that have occurred, and
the violation mode.
show port-security [interface interface-id] address Displays all secure MAC addresses configured on all switch interfaces
or on a specified interface with aging information for each address.
show port-security interface interface-id vlan Displays the number of secure MAC addresses configured per VLAN
on the specified interface.
