Switchport Port-Security - Cisco Catalyst 3750-X Command Reference Manual

Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands

switchport port-security

Use the switchport port-security interface configuration command without keywords on the switch
stack or on a standalone switch to enable port security on the uplink interface. Use the keywords to
configure secure MAC addresses, sticky MAC address learning, a maximum number of secure MAC
addresses, or the violation mode. Use the no form of this command to disable port security or to set the
parameters to their default states.

(Optional) Specify a secure MAC address for the interface by entering
a 48-bit MAC address. You can add additional secure MAC addresses
up to the maximum value configured.
(Optional) On a trunk port only, specify the VLAN ID and the MAC
address. If no VLAN ID is specified, the native VLAN is used.
(Optional) On an access port only, specify the VLAN as an access
VLAN.
(Optional) On an access port only, specify the VLAN as a voice VLAN.
The voice keyword is available only if voice VLAN is
Note
configured on a port and if that port is not the access VLAN.
(Optional) Enable the interface for sticky learning by entering only the
mac-address sticky keywords. When sticky learning is enabled, the
interface adds all secure MAC addresses that are dynamically learned to
the running configuration and converts these addresses to sticky secure
MAC addresses.
(Optional) Enter a mac-address to specify a sticky secure MAC address.
(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
determined by the active Switch Database Management (SDM)
template. See the sdm prefer
total of available MAC addresses, including those used for other
Layer 2 functions and any other secure MAC addresses configured on
interfaces.
The default setting is 1.
