TCP/IP CONFIGURATION 10 - 6
Using ARP to Configure the Print Server IP
Address
If you are unable to use the BRAdmin application or the printer’s
control panel and your network does not use a DHCP server, you can
also use the ARP command. The ARP command is available on
Windows
® systems that have TCP/IP installed as well as Unix
systems. To use arp enter the following command at the command
prompt:
arp -s ipaddress ethernetaddress
Where ethernetaddress is the Ethernet address (MAC address)
of the print server and ipaddress is the IP address of the print
server. For example:
Windows ® Unix/Linux Systems
Tipically, Windows ® Unix and Linux Systems require the hash "-"
character between each digit of the Ethernet address.
arp -s 192.189.207.2 00-80-77-31-01-07
