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.
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.

Enter User ID:
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.
This section describes how to enter a command for those who are unfamiliar with Cisco WAN switch equipment. It also describes the on-line 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. Figure 1-1 lists the command categories. 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 the Return key. The selected command appears on the screen, and the system prompts you for any additional parameters needed to complete the 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.
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.
| Category | Description |
|---|---|
Control Terminal | These commands let you configure your password, serial port and printer functions, use the help facility, establish virtual terminal connections, and create and edit jobs. |
Configuration network and line timing | These commands configure voice and data channels, and display network configuration. |
Lines | These commands activate and deactivate lines and display line status. |
Network | These commands add and delete trunks, configure a node name, and display and print network status. |
Connections | These commands add, delete, and display circuit (voice and data) and FastPacket data channel connections, configure network routing and connection characteristics (Frame Relay and ATM), and perform connection. |
Cards | These commands activate, deactivate, and reset printed circuit cards, and display power supply status. |
Alarms and Failures | These commands display, print, and clear alarms, errors, and network history. They also configure alarm thresholds. |
You can abort any command by pressing the DELETE key [on terminals without a DELETE key, you may need to type 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.
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.

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:
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.
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.

| DELETE | Aborts command. |
| Ctrl-M | Carriage return. |
| RETURN | Carriage return. |
| Ctrl-S | Stops the data flow from the node to the terminal screen. |
| Ctrl-Q | Restarts the flow of data from the IGX. |
| Ctrl-A | Copies the last command line. |
| ! (..) | (The exclamation mark followed by the first characters or character of a command, brings that command back to the command line.) |
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.
The screens and examples in this manual come network equipped with BPX and IGX nodes with both narrowband (T1 and E1) trunks and broadband (DS-3 and OC-3) ATM trunks. IGX nodes run T3, E3, T1, E1, OC-3 and IMATM services.
Commands associated with optional software features function only if the option has been purchased and activated for each node in the network. Optional features are activated from the Cisco TAC. The features that fall into this category are:
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.
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 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.
| Trunk, line, or channel | Description |
|---|---|
CDP/CVM Circuit Line and | The number assigned to a CDP or CVM line (CLN) or an NTC or NTM trunk (TRK) is the slot number of the BC-T1 or BC-E1 back card in the physical slot where the CLN or TRK is connected to the IGX node. In the case of redundant pairs, it is the slot associated with the primary back card. |
AIT Trunk | The number assigned to the backslot of the BC-T3 or BC-E3 back card. |
BPX Trunk Numbers | The number assigned to a BPX trunk (TRK) is the backslot number and port (1 - 3) of the BNI (slot.port; example, 2.1) card to which the T3 trunk cable is attached. |
Voice Channel Numbers | A voice channel is specified by "SLOT.CH". Sets of voice channels are specified by "SLOT.CH-CH". The notation "SLOT" refers to the back slot number of a circuit line and "CH" refers to a channel (1-24 for T1 or 1-31 for E1). For example, "12.1" indicates channel 1 on circuit line 12, and "12.1-9" indicates channels 1-9 on circuit line 12. |
Data Channel Numbers | Data channels are specified by "SLOT.PORT", where "SLOT" refers to the slot number of a data card, and "PORT" refers to a port on that data card. For example, "9.3" specifies port 3 on the data card in slot 9. The notation "9.1-4" refers to ports 1-4 on that card. The range of port numbers is from 1 to 4 for SDI and DDS data cards. An appended "a", for example; 11.1-5a, indicates the channels are configured to use the super-rate alternating channel feature. |
Frame Relay channel | In the local addressing convention, Frame Relay channels are specified by "SLOT.PORT.DLCI", where "SLOT" refers to the slot number of an FRP, "PORT" refers to a port on the FRP card, and "DLCI" is the local data link connection identifier. The range of port numbers is from 1 to 4. For example, the following addcon command at node alpha:
The command adds a connection between alpha and beta. The user device at alpha refers to this connection using the local DLCI of 101. The user device at beta refers to this connection using the local DLCI of 102. The DLCIs have local significance only. With local addressing, the same DLCI can be used again, but not for more than one destination from the same port. For example, the following adds another connection from alpha port 6.1:
In this case, a DLCI of 100 is used at alpha. A DLCI of 102 can be used at gamma as well as at beta, because the DLCIs have only local significance. |
Frame Relay channel numbers (Global Addressing) | In the global addressing, the format for Frame Relay channel specification is "SLOT.PORT.DLCI." However, each FRP or FRM port (and associated user device) is identified by a unique DLCI. No two ports in the network can have the same DLCI. For example, alpha port 6.1, gamma port 6.2, and beta port 4.1 could be assigned unique DLCIs of 79, 80, and 81 when adding connections, as in the following example:
The user device at alpha refers to the connection between alpha and gamma, using the DLCI of 80 assigned to gamma. The user device at gamma refers to this connection using the DLCI of 79 assigned to alpha. The user device at alpha refers to the connection between alpha and beta using the DLCI of 81 assigned to beta. The user device at beta refers to this connection using the DLCI of 79 assigned to alpha. The user device at beta refers to the connection between beta and gamma using the DLCI of 80 assigned to gamma. The user device at gamma refers to this connection using the DLCI of 81 assigned to beta. For information on adding Frame Relay connections through a FastPAD, refer to the command descriptions in the online version of the 8.2 FastPAD User's Guide. |
