IPLink 2800 Quick Start Guide
3.
Open a Telnet connection to the default LAN IP address of the IPLink (
192.168.1.1
).
Use the name
administrator
after the login prompt and simply press the
Enter
key after the
password prompt.
login:
administrator
password:
2803/K/EUI>
Note
The prompt includes the model number of your IPLink (
2803/K/EUI
in the example above) of the WAN
(ETH 0/0) port.
4.
After you have successfully logged in you are in the operator execution mode, indicated by '>' as com-
mand line prompt. With the commands
enable
and
configure
you enter the configuration mode.

2.3 Changing the IP address
When you connect the WAN interface
eth 0/0
, the WAN port operates as a DHCP client and acquires its IP
address/netmask from the WAN network’s DHCP server. However you can change the configuration of the
Eth
0/0
from DHCP client to a fixed IP address as follows. In this example, we assume a private network since the IP
address changes to 172.16.1.100 with netmask of 255.255.255.0.
1.
Select the context IP mode to configure an IP interface.
2803/K/EUI(cfg)#
context ip router
2803/K/EUI(ctx-ip)[router]#
2.
Set your IP address and network mask on the WAN IP interface
eth0
. (Contact your network administra-
tor if you are not sure what IP address to set.)
2803/K/EUI(ctx-ip)[router]#
interface eth0
2803/K/EUI(if-ip)[eth0]#
ipaddress 172.16.1.100 255.255.255.0
172.16.1.100(if-ip)[eth0]#
3.
Store this modified configuration and make it your new start-up configuration. On the next start-up the
system will come up using the modified configuration.
172.16.1.100(if-ip)[eth0]#
copy running-config startup-config
172.16.1.100(if-ip)[eth0]#
Now the IPLink can be connected to your IP network. Remember that if
Eth 0/0
remains as a DHCP client, it gets
the IP address from your IP network’s DHCP server. If you changed the IP address as we showed in this example,
it assumes your IP network (actually Ethernet segment) is on the same subnet, 192.16.1.0/24.
