2. Since the ARP request packet is broadcasted, all hosts in the LAN can receive it. However,
only the Host B recognizes and responds to the request. Host B sends back an ARP reply
packet to Host A, with its MAC address carried in the packet.
3. Upon receiving the ARP reply packet, Host A adds the IP address and the corresponding
MAC address of Host B to its ARP Table for the further packets forwarding.
ARP Scanning function enables the switch to send the ARP request packets of the specified IP
field to the Hosts in the LAN or VLAN. Upon receiving the ARP reply packet, the switch can get
the IP address, MAC address, VLAN and the connected port number of the Host by analyzing
the packet and bind them conveniently.
