Configuring Port Security
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:

Step 3
switchport mode {access | trunk}
Set the interface switchport mode as access or trunk; an interface in the
default mode (dynamic auto) cannot be configured as a secure port.

(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 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

(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.
Note
The voice keyword is available only if a voice VLAN is configured
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.
