Configuration Example

Adding a Static MAC Address Entry Manually

Network requirements

The server connects to the device through GigabitEthernet 1/0/2. To prevent the device from broadcasting packets destined for the server, it is required to add the MAC address of the server to the MAC address table of the device, which then forwards packets destined for the server through GigabitEthernet 1/0/2.

zThe MAC address of the server is 000f-e20f-dc71.

zPort GigabitEthernet 1/0/2 belongs to VLAN 1.

Configuration procedure

# Enter system view.

<device> system-view

# Add a MAC address, with the VLAN, ports, and states specified.

[device] mac-address static 000f-e20f-dc71 interface GigabitEthernet 1/0/2 vlan 1

# Display information about the current MAC address table.
