Configuring Port-Based Traffic Control
Enabling and Configuring Port Security
Beginning in privileged EXEC mode, follow these steps to restrict input to an interface by limiting and
identifying MAC addresses of the stations allowed to access the port:
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
switchport mode {access | trunk}
Step 4
switchport voice vlan vlan-id
Step 5
switchport port-security
Step 6
switchport port-security
[maximum value [vlan {vlan-list |
{access | voice}}]]
OL-12247-04
Purpose
Enter global configuration mode.
Specify the interface to be configured, and enter interface configuration
mode.
Set the interface switchport mode as access or trunk; an interface in the
default mode (dynamic auto) cannot be configured as a secure port.
Enable voice VLAN on a port.
vlan-id—Specify the VLAN to be used for voice traffic.
Enable port security on the interface.
(Optional) Set the maximum number of secure MAC addresses for the
interface. The maximum number of secure MAC addresses that you can
configure on a switch or switch stack is set by the maximum number of
available MAC addresses allowed in the system. This number is set by the
active Switch Database Management (SDM) template. See
"Configuring the Switch SDM Template."
available MAC addresses, including those used for other Layer 2 functions
and any other secure MAC addresses configured on interfaces.
(Optional) vlan—set a per-VLAN maximum value
Enter one of these options after you enter the vlan keyword:
vlan-list—On a trunk port, you can set a per-VLAN maximum value on
•
a range of VLANs separated by a hyphen or a series of VLANs separated
by commas. For nonspecified VLANs, the per-VLAN maximum value is
used.
access—On an access port, specify the VLAN as an access VLAN.
•
•
voice—On an access port, specify the VLAN as a voice VLAN.
The voice keyword is available only if a voice VLAN is configured
Note
on a port and if that port is not the access VLAN. If an interface is
configured for voice VLAN, configure a maximum of two secure
MAC addresses.
