Configuring the Nortel Networks Remote Access Concentrators and the DMS-10 for Remote Access.March 31, 1999 13

Figure 6 illustrates the entry points to the various levels of the CLI monitor. Each level

provides different functions.

The ROM monitor provides the basic IP setup to configure the ethernet interface. In order

to get into the “boot” monitor it is necessary to put the RAC into a setup mode using a

front panel pushbutton. Refer to Bay documentation for this. The boot monitor allows

basic testing of the device prior to booting. In the ROM monitor the IP address must be set

along with the subnet mask and boot IP address if the RAC is to be booted off a network

device. If the RAC is to be “stand alone” the boot sequence will need to be modified so it

boots off of itself and does not try to boot off of the network. In order to leave ROM mon-

itor a boot must be executed from the command line. This causes the RAC to load it oper-

ation code.

Once the Boot has been performed using the serial port the Console Monitor becomes

available. The entry point is the “Console:” monitor prompt. Type CLI to enter the

CLI monitor. CLI as shown in Figure 1 has several levels. If security has been enabled,

which is discussed later, a user and password will be needed. The first level indicated by

the “annex:” prompt provides only basic function. In order to move to where changes can

be made the operator must login as Super User (SU). The initial password is the IP address

assigned to the RAC in the ROM monitor. Once logged in the password should be updated

to a more secure choice. The Super User CLI indicated by the “annex#” prompt provides a

much larger choice of function. Figure 6 only shows a subset of the most useful com-

mands.

The actual setup of the WANs and other important functions are handled in the Admin

portion of CLI. This level is selected by typing “admin”, once logged in as super user. This

will invoke the “admin:’ prompt to be displayed. At this level the commands deal with set-

ting, showing and resetting devices. Things which can be set, reset or shown are, port,

annex, wan, interface or modem. It is a good idea to show an interface prior to making any

changes since it will provide a guideline for the settings and their spelling. Ports are logi-

cal devices which manage data. The port types are:

• ta- this port manages V.120, V.110, and X.25 calls

• syn- this port manages PPP and MLPP calls

• asy- this port manages asynchronous voice calls associated with digital modems.

Note

The command line help is available at each level of CLI by typing

“help” or “?”.

Note:

The default prompt is “annex”. It can be set to other strings

in the prompt

definitions.
