IGX and BPX Fundamentals
A workstation, terminal, or a PC can function as a control terminal for an IGX or BPX node through an EIA/TIA-232 link or over an Ethernet TCP/IP LAN. All command input takes place at the terminal, and all displays appear on the terminal screen. Through displays that show status, alarm, or statistics, the terminal constantly provides a view of an individual node, a trunk, a connection, or the entire network.
The control terminal gives you the ability to control the network from any routing node. A remote access command is available for controlling the network from a node other than the node physically connected to the terminal. This command is the Virtual Terminal (vt) command. The vt command creates a communication channel for the operator to a remote node. After you access a node by using vt, you can begin executing commands at the accessed node. Most commands and tasks that you can execute at the local node are also executable at a remote node.
The WAN Manager Network Management Station provides network management capabilities for multi-node networks. WAN Manager also collects and displays statistics. For access, WAN Manager operates in LAN mode or telnet mode. (As of Release 8.0, you can no longer access a node through the serial port.) Refer to the Cisco WAN Manager Operations Manual for more information.
Powering Up the Control Terminal
After the node receives power and correctly starts up, the terminal screen appears as shown below. If the screen is blank or does not display the initial screen, check all connections to the node, and make sure the terminal and node are receiving power. If the connections are correct, press the Delete key a few times or cycle the terminal power.

The User Command Screen Layout
The screen has three areas. The top line of the screen (status line) displays the node name, current user name, software revision level, date, time and time zone. If the date and time have not been configured on the node, the screen states this.
The middle part of the screen shows the information returned by the executed commands. This could be, for example, configuration or statistical information.
The bottom area of the screen displays prompts for the next command or the current command parameters. As the system receives the parameters you enter, it duplicates them above the command entry line to serve as a record of the entries. The bottom area also shows the command last entered.
All command screens eventually time out. This includes dynamically updated screens such as the display for the dspbob command. Furthermore, if sufficient time passes, you are logged out.
Entering a Command
This section describes how to enter a command for those who are unfamiliar with Cisco WAN switch equipment. It also describes the online help for the commands.
Each user command can have one or more privilege levels. Entering a particular command is possible for a user at the same or higher privilege of the command. Each definition in this manual shows the privilege or range of privileges for the command. Most commands are not case-sensitive.
When the Next Command prompt is at the bottom of the screen, the system is ready for a new command. Some commands do not require parameters. These usually are commands for displaying information. Display commands often have no required parameters but have one or more optional parameters for changing the scope of displayed information. Commands that require parameters usually prompt for each parameter. To abort a command for any reason, press the Delete key. More information for altering command line entries appears in the forthcoming section called "In case of a mistake."
The general syntax is command <parameter(s)> [optional parameter(s)]. When a command definition displays actual parameters, the required parameters appear within the arrow heads (<>). If the list of command parameters is too long, the command definition's "Syntax" field just shows "parameters," which means the parameters are available only in the parameters table for the definition. For information on the format of system resource numbering, see the section "How network trunks, lines, and channels are numbered."
Users who are not familiar with the system can use the online help feature to become familiar with the categories of commands and get syntax information on a command. Seven categories of commands exist. The figure below lists them. To enter a command from the menu, do the following:
Step 1 At the Next Command prompt, either press the Escape key or enter the word help or a question mark. A list of command categories appears as in the example below.
gamma TRM YourID:1 IGX 8420 9.2 Aug. 15 1998 13:47 CST
All commands fall into one (or more) of the following categories:
Control Terminal
Configuration
Lines
Network
Connections
Cards
Alarms and Failures
This Command: ?
Use cursor keys to select category and then hit <RETURN> key:
Step 2 Use the up/down arrow keys to select a command category, then press Return. A listing of all the commands in that category appears. (The next example is from the "line" category of commands.)
Step 3 Use the cursor key to select the command you want to enter (dsptrks for example), then press Return. The selected command appears on the screen, and the system prompts you for any additional parameters needed to complete the command.
Figure 1-1 Entering a Command
A faster way to enter a command, using fewer keystrokes, is to enter the command on the command line, then press the Return key. The system prompts you for any additional parameters required to complete the command. The fastest way to enter a command, using the fewest keystrokes, requires that you know the command along with the necessary parameters. Enter the command name and all of the required parameters in the correct format, then press the Return key.
About Command Categories
The command category menu is listed when you press the Escape key. The commands are organized into seven categories. (These categories are not the categories used to organize this manual.) Table 1-1 lists and describes the command categories.
Aborting a Command
You can abort any command by pressing Delete [on terminals without a Delete key, you may need to press Shift-Backspace or some other key(s) to perform the Delete function]. The Next Command: prompt appears at the bottom of the screen indicating that you can enter another command. The command you aborted appears in low intensity letters on the screen after the Last Command: prompt.
About Command Names
Most of the command names follow a descriptive verb and noun format. For example, the addcon command adds a connection, the delcon command deletes a connection, and the dspcon command displays information about a connection. Table 1-2 lists the command-related abbreviations.
Command Shortcuts
When you enter a command, it displays next to the Last Command: prompt at the bottom of the screen. To copy the command to the new command line, press the Ctrl and A keys simultaneously. To execute the previous command, you can edit the command line and then press the Return key. You can also enter an exclamation mark (!) followed by the first letter or letters of a previous command and press the Return key. For example, to repeat the dspcons command:
Last Command: dspcons
Next Command: !dsp
Press the Return key. You can use the Display Command History (.) command to display the 12 most recently executed commands:
Step 1 Type . (a period) and press Return. A numbered list of commands displays. In the following example, the most recently executed command is numbered 1.
12: 11: 10: 9: 8: 7: prtscrn 6: addcon 12.1 alpha 12.1 v 5: delcon 12.1 4: cnfport a 1200 n 8 1 x x n 3: cnftime 17 19 34 2: redscrn 1: help
Step 2 Type the number of the command you want to re-execute, then press the Return key. The command displays after the Next Command: prompt. You can press the Return key to execute the command, or you can edit the command line and then press the Return key. Whenever you end a terminal session by signing off (with the bye command), the command list is cleared.
In Case of a Mistake
Before you press Return, you can use control keys to edit a typed command. Table 1-3 lists the control key you can use to edit information on the command line. Not all terminals have the same key characters. If the exact key is not available, determine which key performs the function.
Access Privileges
Access to the commands is password protected. To access the commands, type your user ID and user password at the log-in prompts. Each user is assigned a privilege level by the System Manager which determines what commands you can use. There are six user privilege levels, ranging from 1 to 6. Level 1 has access to all the commands and level 6 has access to the fewest commands. A given privilege level has access to all levels below it. For example, level 3 has access to levels 3 through 6. The privilege level for each command is part of the command summary. User ID and passwords are case-sensitive.
Help
The system software provides a help function for commands. The help consists of a list of all commands and a display of command syntax. Entering "help" or "?" with no parameters displays a list of the seven command categories (see the list that follows). Entering "help" and a command name displays the command syntax. Entering "help" and a few letters of a command name lists all commands containing these characters. For example, "help fr" lists all commands containing the letters "fr." You can then select a particular command from this list for help information.
•Control terminal
•Configuration
•Lines
•Network
•Connections
•Cards
•Alarms and failures
The Online Help feature of WAN Manager provides more detailed command information. Hypertext links allow you to navigate through command category lists, alphabetical indexes, and the command descriptions. Refer to the Cisco WAN Manager Operations manual for more information.
The Numbering of Trunks, Lines, and Channels
The information contained in this manual allows you to set up, configure, and maintain traffic on trunks and lines. Table 1-4 lists the format conventions for the names of trunks, lines, and channels.
