Configuring and Monitoring Port Security
Port Security
Configuring Port Security
Using the CLI, you can:
■
Configure port security and edit security settings.
■
Add or delete devices from the list of authorized addresses for one or more
ports.
■
Clear the Intrusion flag on specific ports
Syntax:
port-security
[e] <port-list>< learn-mode | address-limit | mac-address | action |
clear-intrusion-flag >
<
port-list
>:
Specifies a list of one or more ports to which
the port-security command applies.
learn-mode < continuous | static | port-access | configured | limited-
continuous >
For the specified port:
• Identifies the method for acquiring authorized
addresses.
• On switches covered in this guide, automatically
invokes eavesdrop protection. (Refer to “Eavesdrop
Protection” on page 13-5.)
continuous
(Default): Appears in the factory-default
setting or when you execute
no port-security.
Allows the port
to learn addresses from the device(s) to which it is
connected. In this state, the port accepts traffic from any
device(s) to which it is connected. Addresses learned in
the learn continuous mode will “age out” and be
automatically deleted if they are not used regularly. The
default age time is five minutes.
Addresses learned this way appear in the switch and port
address tables and age out according to the
MAC Age
Interval
in the System Information configuration screen
of the Menu interface or the
show system information
listing.
You can set the MAC age out time using the CLI, SNMP,
Web, or menu interfaces. For more information on the
mac-age-time
command refer to the chapter titled
“Interface Access and System Information” in the
Management and Configuration Guide
for your switch.
