4.8.2 HTTPget and ARP to Setup Device IP Address
Use the
iConnect
software, which may be downloaded from our website, to do
these IP changes whenever possible.
Use ARP first to assign the mac address to a static IP address in computer arp table by
this command:
arp –s 192.168.1.200 00-03-34-00-06-b6
Then use the following command to assign new IP to the device:
httpget –r –S "00000000" 192.168.1.200:1
where:
“
0000000
” is admin. password. If the password is wrong, the unit will ignore the new IP.
If the new IP is taken, you will get the message " New IP is Assigned" after the HTTPget
command. The device will reset automatically.
“
192.168.1.200
” is an example of an IP address. It is replaced with IP address suitable
for your network
“
00-03-34-00-06-b6
” is replaced with your iServer product MAC address.
4.9 ARP Protocol
ARP is the Internet layer protocol responsible for matching or obtaining the MAC
(hardware) address that corresponds to a particular IP address. The ARP command
allows the user to view the current contents of the ARP cache of the local computer
(residing on the same network).
Microsoft includes the ARP.EXE utility for viewing and modifying the ARP cache with its
Windows products. The following ARP commands can be used to view cache entries:
•
arp –a
➞
Use this command to view all ARP cache entries.
•
arp –a
plus
IP address
➞
Use this command to view ARP cache entries associated
with one particular interface on a network with multiple adapters.
•
arp –g
➞
Same as arp –a.
•
arp –N
➞
Use this command to display ARP entries for specific network interface.
•
arp – s
plus
IP address
plus
Physical address
➞
Use this command to manually
add
a permanent static entry to the ARP cache.
•
arp –d
➞
Use this command to manually delete a static entry.
Ping the destination computer using IP address first before using the arp -a
command.
