Common MAC Address Operations : Configuring Port Security

Port security implements dynamic binding. After the maximum number of MAC addresses that can be learned by an interface is set, other non-trusted hosts cannot use the local interface to communicate with the switch, thereby improving the device and network security.

# Configure port security on the gigabitethernet0/0/1.

<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] port-security enable

<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] port-security enable
[HUAWEI-GigabitEthernet0/0/1] port-security max-mac-num 5

NOTE:

Before setting the maximum number of MAC addresses that can be learned by an interface, ensure that the interface has been enabled with port security.
