Configuration Example

Adding a Static MAC Address Entry Manually

Network requirements
The server connects to the switch through GigabitEthernet 1/0/2. To prevent the switch 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 switch, which then forwards packets destined for the server through
GigabitEthernet 1/0/2.
The MAC address of the server is 000f-e20f-dc71.
Port GigabitEthernet 1/0/2 belongs to VLAN 1.
Configuration procedure
