Configuring Port Security

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 GE1/0/1.

<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 1/0/1
[HUAWEI-GigabitEthernet1/0/1] port-security enable
# Set the maximum number of MAC addresses that can be learned by the GE1/0/1 to 5.
<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 1/0/1
[HUAWEI-GigabitEthernet1/0/1] port-security enable
[HUAWEI-GigabitEthernet1/0/1] 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.
