3.2 Assigning a new IP Address by ARP command
Arp –s is used to assign a static IP address of GW51W-
MAXI
and add this static entries to the Arp cache of
the computer, when TCP/IP packet with destination port number 1 is sent to GW51W-
MAXI
, it causes the
device to check its MAC address with IP address, once GW51W-
MAXI
finds those two unmatched, it will
reboot and change to the new IP address which was set by Arp –s command. The following example uses
ARP to assign a static IP address of GW51W-
