ACCESSING THE CONFIGURATION
I
NTERFACE
This chapter explains how to attach to the configuration interface locally via the
console port or remotely via a Telnet session. This chapter also introduces you to
the capabilities and conventions associated with management of your
OfficeConnect Remote 812.
Establishing
Communications
with the
OfficeConnect
Remote 812
Local Connection If you want to attach locally to the OfficeConnect Remote 812 via the console
(serial) port, you will need to connect the supplied serial cable to the Console Port
located on the unit and the Serial Port on your computer. In addition, you will also
need a terminal emulation program appropriate for your computer. See the
following subsections for various emulation options.
No matter which emulator you use, configure your settings to:
9600 baud
8 data bits
no parity
1 stop bit
direct connect
IBM-PC Compatible Computers
Windows Terminal (included with Microsoft Windows) and ProComm Plus are
popular communications packages which support VT100 terminal emulation for
IBM-PC compatible computers. HyperTerm, bundled with Windows 95, also
provides terminal emulation.
Macintosh Computers
ProComm, MicroPhone, White Knight, Kermit, Red Ryder, VersaTerm and ZTerm (a
shareware application available on the Internet and many online services) are
popular communications programs which carry vt100 terminal emulation service
for Macintosh computers. If you don’t have a communications package or your
program doesn’t support vt100 emulation, ZTerm will function just as well.
1-2 CHAPTER 1: ACCESSING THE CONFIGURATION INTERFACE
UNIX-Based Computers
Kermit, minicom and tip are typical terminal emulation programs for UNIX-based
computers. Depending on the platform you’re using, you may need to modify a
configuration file for vt100 settings.
Remote Connection If you want to attach to the OfficeConnect Remote 812 via the LAN or WAN
interface of the unit, you will need to establish a Telnet connection to the unit.
The OfficeConnect Remote 812 must have an IP address and an administrative
login profile (username and password) in order to connect to it with Telnet. The IP
address and administrative login profile are automatically created when the unit is
initially configured using the IP Wizard or in DHCP Smart Mode. The default
username is 'root' and the default password is '!root'. Refer to the OfficeConnect
Remote 812 ADSL Router Install Guide for information on the IP Wizard or DHCP
Smart Mode initialization. Alternatively, the IP address and administrative login
profile can be created with CLI using the QuickSetup program or using individual
commands.
From Windows 95, you can go to the DOS Window and run:
telnet <ip_address>
This will bring up the login prompt for the unit. Once you have successfully
logged in, the Command Line Interface presentation is the same as if you were
locally attached.
When you want to terminate your Telnet session, type quit at the CLI prompt.

CLI COMMAND CONVENTIONS AND
T
ERMINOLOGY
This chapter describes the command syntax, conventions and terminology used
within the Command Line Interface. Reviewing and understanding this chapter is
essential for you to understand subsequent chapters.
Command
Structure
Format Commands can be followed by values and/or parameters and values. For example:
add ip network <network_name>
address [ip_addr]
{ interface [eth:1] }
add ip network is the command
<network_name> is the (required) value for the command
address is a required parameter
[ip_addr] is the value for the IP address parameter which you must provide
interface is only required if you want to override the default value, which is
eth:1
Parameters
are order independent
{} parameters enclosed by curly braces are required, and are provided with
default values. You do not need to specify these parameters unless you wish to
override the default.
Values
<> required values for a command or parameter are enclosed by arrows.
[] range of values following parameters are enclosed in brackets. Inside the
brackets, if you see a:
| (vertical bar) you may select only one of the displayed choices:
[FIRST | SECOND | THIRD]
, (comma) you can select one or more of the displayed choices:
[FIRST,SECOND,THIRD,...]
The type of value you enter must match the type requested. Numbers are
either decimal or hexadecimal. Text can be either a string that you create, or it
2-2 CHAPTER 2: CLI COMMAND CONVENTIONS AND TERMINOLOGY
may be a list of options you must choose from. When choosing an option, type
the text of the option exactly.
Names or Strings
“Double quotation marks” set off user-defined strings. If you want white space
or special characters in a string, it must be enclosed by “double quotation
marks”.
Network Address Formats
Many commands require a network address, to define a link to a remote host,
workstation or network. Network addresses are shown in this document using the
syntax described in the following table:
Abbreviation and
Command
Completion
Commands can be abbreviated if arguments you write are unique.
For example, you can type se vc jay pa bird, short for: set vc jay password
bird is acceptable, but se vc jay i 222.111.111.111 isn’t unique because i can
stand for ip, ip_routing, or ip_source_validation.
As a convention, some commands illustrated in this manual are abbreviated
and annotated as such (abbr.) for brevity.
Also, some parameters are omitted in examples because they default to
standard values and do not require entry, or are unnecessary for common
configuration. See the CLI Reference section for more details.
Command completion finishes spelling a unique, abbreviated parameter for
you just by pressing the key. Its handy when you’re in a hurry or uncertain
about a command. For example, if you type add ip n[ESC], it will spell out the
keyword network without losing your place in the command syntax.
Control Characters Commands can be retrieved by typing <ctrl>p [^p] (for previous) and <ctrl>n
[^n] (for next). Command retrieval consults the history of previous fully entered
commands, defaulting at the last ten commands. If an error occurs while a
command is processing, any partial command (up to and including the field in
error) is added to the history list.
The current command can be killed by pressing <ctrl>c [^ c].
A partially completed command line can be reprinted - a useful function if, due
to interrupted output, you’re unsure what OfficeConnect Remote 812 has
“seen” up to now - by pressing <ctrl>l [^ l] (for last).
Help Help is general or positional. Type help <any command> to get a cursory list
of associated commands and its syntax. Type <any command> ? to get more
extensive, positional help for a particular field. Help is most useful during
configuration: query the list of possible parameters by typing ? and, when you
find the value you need, type it without losing your place in the argument. Just
be sure to leave a space between the keyword and the question mark.
Address Type Format Range
IP_address a.b.c.d 0.0.0.0 to 255.255.255.255
(decimal)
ip_net_address a.b.c.d/mask 255.255.255.255/A,B,C,H
mac_address xx:xx:xx:xx:xx:xx hexadecimal digit pairs
Command Structure 2-3
Conventions
Conventions
Most commands are not case sensitive. As a rule, only <name> and [password]
values require typing the correct case.
Configuration changes occur immediately but are lost on reboot unless you
save them. The save all command places configuration changes in FLASH
ROM (permanent memory). The changes are lost if not saved to FLASH ROM or
if power is lost before you can save them.
Commands to delete a network user, interface, route, TCP connection,
community name, network service and others cannot take place unless the
process or function has first been disabled.
Wherever an IP address value is required, you can enter a host name provided
you have configured a DNS server or put the name and address into the DNS
Local Host table.
Command Language
Terminology
The CLI command language creates, manages, displays and removes system
entities. These entities describe system and network connections and processes.
Most of the managed entities in the system are slotted in tables. Some common
examples are:
Network - defines local and remote networks, network connections, hosts
and routers
VC - A table of parameters that describes connection parameters associated
with a remote site. These parameters are used when establishing a network
connection over the WAN.
User - A table of parameters that describes connection parameters associated
with Telnet users that wish to attach and remotely manage the unit.
Filter - can be applied to interfaces, connections, and users to control access
through the system
Interface - describes physical devices; for example, ports
Syslog Host - receives system messages
DNS Server - translates IP addresses to and from host names
Route - describes a path through the network to another system or network
Table entries are created with an add command, and removed with a delete
command. The add command specifies the most important parameters of the
entry. Additional parameters are usually specified with the set command, which is
also used to change configured parameters.
The list command displays table entries. For example, list users displays all
defined administrative login profiles.
The show command displays detailed information about a specific table entry. For
example, show user root displays detailed information for the administrative
login profile root.
