Configuration Examples for Port Security
This example shows how to enable port security on a port and to set the maximum number of secure addresses
to 50. The violation mode is the default, no static secure MAC addresses are configured, and sticky learning
is enabled.
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security maximum 50
Switch(config-if)# switchport port-security mac-address sticky
This example shows how to configure a static secure MAC address on VLAN 3 on a port:
Switch(config)# interface gigabitethernet1/0/2
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security mac-address 0000.0200.0004 vlan 3
This example shows how to enable sticky port security on a port, to manually configure MAC addresses for
data VLAN and voice VLAN, and to set the total maximum number of secure addresses to 20 (10 for data
VLAN and 10 for voice VLAN).
Switch(config)# interface tengigabitethernet1/0/1
Switch(config-if)# switchport access vlan 21
Switch(config-if)# switchport mode access
