APPENDIX C CONFIGURATION WITHOUT A CONSOLE

When a terminal or PC is not available for use as a console, the router has a special feature that allows configuration of the Ethernet interface from any PC on the LAN. The router “adopts” the destination IP address of the first non- UDP packet received from the LAN and accepts the connection. (After configuration of the Ethernet interface, with or without a console, the remaining configuration can be done via telnet.)

It is recommended that a console be used for the initial configuration of the router, due to the hardware and software diagnostic messages given on the console screen. If a console is not available, follow the instructions in this appendix to configure the Ethernet interface.

Requirements

The router must be set to the factory default. If the router is being moved from one location to another, the configuration should be reset using the menu option ADMIN =>LOAD CONFIGURATION =>FACTORY DEFAULTS before the router is moved.

Procedure

1Edit the ARP table of the PC in the LAN and associate the MAC address of the router (affixed to the underside of the router) to the IP address for the interface. In Unix and Microsoft Windows systems, the command to manipulate the ARP table is something similar to arp -s <IP address> <MAC address>. In Unix, type man arpfor help. In Microsoft Windows, type “arp /?” for information about this command.

2Telnet to the IP address specified above. The router will receive the packet because of the modified ARP table and use the IP address for its Ethernet interface.

3The new IP address is saved only in run memory. The configuration must be explicitly saved to flash using the menu option ADMIN =>WRITE CONFIGURATION =>TO FLASH. Do this now.

4The Ethernet and other interfaces can now be configured using the telnet session established.

If the connection fails or if the link goes down before the IP address is saved to flash, a console must be used.
