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. 
z 
The MAC address of the server is 000f-e20f-dc71. 
z 
Port GigabitEthernet 1/0/2 belongs to VLAN 1.
