Configuration Examples for Port-Based Traffic Control
Enabling Unicast Storm Control: 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 gigabitethernet1/1
Switch(config-if)# storm-control unicast level 87 65
Enabling Broadcast Address Storm Control on a Port: Example
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 GigabitEthernet1/17
Switch(config-if)# storm-control broadcast level 20
Purpose
Displays the administrative and operational status of all switching
(nonrouting) ports or the specified port, including port blocking and port
protection settings.
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.
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.
Displays all secure MAC addresses configured on all switch interfaces or
on a specified interface with aging information for each address.
Displays the number of secure MAC addresses configured per VLAN on
the specified interface.
Displays 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.
Displays the interface configuration.
Displays switch-port information.
Displays port-security settings for an interface or for the switch.
Displays PSP configuration details for protocols.
