device# configure terminal device(config)# interface Ethernet 3/2 device(conf-if-eth-3/2)# do show run interface Ethernet 3/2 interface Ethernet 3/2 switchport switchport mode trunk switchport port-security switchport port-security max 10 switchport port-security mac-address 3200.1110.0002 vlan 250 switchport trunk allowed vlan add 250 switchport trunk tag native-vlan no shutdown
To display the port MAC security configuration details across ports on the device, enter the following command:
device(conf-if-eth-3/2)# do show port-security Secure MaxSecureAddr CurrentAddr StaticSec Violated Action Sticky Port (count) (count) (count) Eth 3/2 10 0 1 No Shutdown No
To display the statistics of the port MAC security configured for an interface, enter the following command:
