switchport port-security
Use the switchport port-security interface configuration command without keywords to enable port
security on the 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) See the switchport port-security aging
(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.
Note The voice keyword is available only if voice VLAN is
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 is set by the maximum number of available MAC
addresses allowed in the system, approximately 6000. This number
represents the 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.
