Setting the IP Address Using the ARP
On Windows and UNIX(Linux) platform, the command 'arp' enables a user to change
the contents of arp cache table from the host computer. After changing the contents of
the arp cache table, attempting a Telnet connection or a ping test will change the
ezTCP's IP address. IP address changed by the arp command will not be stored in
EEPROM. Therefore, the user should change the IP-related items by giving "env if"
command through telnet access. ezTCP allows the user to change the IP address only
one time after the power is turned on. For that reason, the user should reset ezTCP
when changing the IP address.
The example listed below shows how to change the arp cache table on Windows' MS-
DOS prompt window and Linux. If ezTCP's Ethernet address is 00:30:f9:00:00:01 and
the IP address to use is a.b.c.d., the user can change the IP address as follows:
z
Windows
C:\>arp -s a.b.c.d 00-30-f9-00-00-01
☜
Change the table.
C:\>arp -a
☜
Check changes.
Interface: xxx.xxx.xxx.xxx on Interface xxxxxxxx
Internet Address Physical Address Type
a.b.c.d 00-30-f9-00-00-01 static
C:\>telnet a.b.c.d
☜
Access the ezTCP.
