Appendix A. Connecting eH880 to the Ethernet Network

Appendix A.1. Configuring Ethernet Port

Each eH880 Demo Unit has a built-in Ethernet port. The eH880 unit is pre-configured to get an IP
from DHCP servers. After the demo program showed on the screen. Press F4 to view the IP address
of the eH880.
It is possible to change the IP manually
After the telnet session has been established, an 'ifconfig' command to view the IP address
assignment can be issued. The following is the example output when ifconfig is issued:
~ # ifconfig
eth0
Link encap:Ethernet HWaddr 00:02:31:05:0A:01
inet addr:192.168.61.123 Bcast:192.168.61.255 Mask:255.255.255.0

inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
On the other hand, users can also configure network parameters. The following sections discuss the
commands and procedures to do so. User can specifically choose either static IP or dynamic IP
address configuration for the eH880 unit. However, note that such changes will not be permanent –
after the device is re-booted again, its IP address will resume the saved setting in the eH880. To
permanently change the IP address, please refer to eH880 tool manual.

Appendix A.1.1. Setting up Loop Back Device

Loop back device is used to refer to local host of the eH880 unit and it has a default IP address
127.0.0.1 with netmask 255.0.0.0.
1. Input the following command to bring up the loop back device interface:
# ifconfig lo 127.0.0.1
2. Input "ifconfig" command to show the configuration:
# ifconfig
lo
Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
