NetCrossing Gateway NX-2E1/T1 Operator’s Manual
4-1
4 COMMANDS
4.1 Configuration techniques
There are three ways to configure the gateway. One uses the RS-232 console port in the unit front
panel. This port is always set to operate with the following parameters:
Baud rate: 9600
Word length: 8 bits
Parity: none
Stop bits: 1
This console port allows configuring and monitoring only the local gateway, i.e. you can not monitor
and configure any of the remote gateways reachable through the WAN port.
A second configuration method uses the gateway LAN Ethernet port. This approach has the
advantage that any gateway reachable across the WAN in a bridge network, can be configured from a
single PC.
In order to use the Ethernet connection to configure the gateways the “Ethernet Console Program”
(Econsole) needs to be installed at a PC. This PC must be connected to the same LAN as the gateway
LAN port. Refer to Appendix C for instructions on the installation of Econsole.
The third configuration method is using Telnet from a remote location. Telnet is explained in more
detail in section 6.
After power up the gateway displays a banner with identifying the hardware and software versions
followed by the command prompt. The default prompt is:
nxg-nnnnn #>
where nnnnn are the last five digits of the gateway serial number. If a node “name” has been
assigned to the unit, the prompt will be that name.
The “help” command provides a list of all the commands available. To get more detailed help for a
specific command, type “help command-name”.
The gateway keeps a history of several of the previously issued commands. Those commands can be
viewed by pressing the up-arrow and down-arrow keys on the keyboard. Any of those previously
issued commands can then be edited and reentered by pressing the <Enter> key.
4.2 Command syntax
The command interpreter in the NetCrossing Gateway is designed to accommodate both a novice as
well as an expert operator. All commands and parameters have descriptive names so that they are
easily remembered and their meaning is clear. In order to be descriptive however, those commands
