This chapter describes the commands for setting up an IPX, IGX, or BPX node. You must set up each node before you build the network. Sections with task descriptions and command summaries appear before the full command descriptions. The task descriptions tell you how to:
Before a node can be added to the network, a unique node name must be assigned. All nodes initially have the default name NODENAME. The node name consists of 1 to 8 printable characters (beginning with a letter), and cannot contain spaces. If you are naming the node after a city or place that contains more than eight characters, you will have to abbreviate the name for use as a node name. The name must be unique across the network. To assign the node the name of alpha, enter:
To change a node name, do the following:
Step 1 Sign on to (or establish a virtual terminal connection with) the node whose name you want to change.
Step 2 Change the name of the node using the cnfname command:
The name of the node you are connected to changes to the new name. This new name is distributed automatically to other nodes in the network.
Each node must be set to a time zone. To set the time zone for the node to Greenwich Mean Time, enter:
Since Rel. 7.0 Packet Lines are referred to as Trunks. Use the letters "trk" in all commands referring to packet lines. To remove a trunk from the network, do the following.
Step 1 Sign on to (or establish a virtual terminal connection with) the node.
Step 2 Delete all packet (trunk) lines attached to the node using the deltrk command. For example, to delete line 5, enter: deltrk 5
An interface shelf is a non-routing device that drives ATM cells to and from a BPX routing hub in a tiered network. An interface shelf is either an IPX node configured as an interface shelf (IPX/AF) or an MGX 8220 edge concentrator. For an IPX or IGX node to serve as an interface shelf, Cisco personnel must first configure it for that purpose. Furthermore, the shelves must be configured to use STI cell headers and BPX Addressing Mode (BAM). An MGX 8220 must have been brought up in the network before you can add it to the tiered network (for instructions, see the MGX 8220 reference documentation.) To add a feeder shelf, use addshelf. To delete a feeder shelf, use delshelf. To view conditions on a feeder trunk, use dspnode. Note that addshelf and addtrk are mutually exclusive commands.
Redundancy is established by installing two identical front and back card sets, connecting them with a Y-cable for each paired port, then specifying redundancy with the addyred command. The commands for setting up and displaying card redundancy are addyred, delyred, dspyred, and prtyred. Redundancy applies to the entire card and is not port or line-specific.
During normal operation, the primary set is "active" and carrying traffic, while the secondary set is in "standby." The primary set determines the configuration of the pair, so the secondary and primary card sets have the same configuration. If the primary is reset or otherwise becomes inactive, the secondary card set becomes active.
IGX card sets may consist of the following:
IPX card sets may consist of the following:
BPX card sets may consist of the following:
The following applies to redundant card sets:
Figure 4-1 illustrates a typical Y-cable connection of primary and secondary card sets.
As depicted in the illustration above, the single end of a Y-cable goes to the user equipment. One of the two connectors at the split end goes to the primary back card, and the other connector goes to the secondary back card.
Switching to the standby card occurs only if the secondary card set is in a Standby or a Standby-T state (not if it is Failed). See the dspcds definition for information on these states.
On multi-port card sets, each primary port is connected by a Y-cable to a secondary (redundant) port. Port 1 of the primary card set must be paired to port 1 of the secondary card set, and so on. Figure 4-2 illustrates the cabling for a multi-port card set.
If the secondary card set becomes active, the primary card set becomes the backup. For the primary card set to serve as a backup, it must be a complete set and not have failed status. These requirements apply to single and multi-port cards.
The addyred command is applicable even if the primary and secondary slots are empty. If cards are in place in the primary and secondary slots, the system checks for card compatibility. Two types of incompatibility can occur: back card and jumper or cable. (On SDI, FRI, and FTI cards, jumpers determine whether a port is configured as DCE or DTE. On LDI cards, either a DCE or DTE adapter cable connects to the LDI port, as applicable).
If incompatibilities exist, the message "Y-Cable Conflict" appears on screen. Specific conflicts are listed in reverse video in the Y-Cable Redundancy screen. See the dspyred description for details. V.35 redundancy requires special redundant jumpers on the SDI or FRI cards that are Y-cabled together. Always use the applicable Y-Cable Redundancy kit for a card.
If your system is configured to control an external device, such as a multiplexer, you can establish a window session to it from the control terminal. While in a window session, any characters you type at the control terminal go to the external device for processing. Any characters generated by the external device appear on the control terminal screen.
The Window to External Device (window) command establishes a window session. You can use this command only if the external device connects to the local node. You can, however, enter the window command during a virtual terminal session so that you have a window session with any external device in the network. To start a window session, use the Virtual Terminal (vt) command to access the node cabled to the device, then invoke the window command. Before starting a window session, you must have configured the port and the port function with cnfterm and cnftermfunc. In addition, you must know whether the external window device is cabled to a node's Control Terminal (RS-232) port or Aux Port (RS-232) port. The format for the window command is:
Enter an a if the external device is attached to the node's Aux Port or c if the device is attached to the node's Control Terminal port. The default for this parameter is Aux Port. To establish a window session with an external device attached to a node's Control Terminal port, enter:
The system responds by redrawing the terminal screen. You can now enter commands and send data to the external device as if you were locally connected to its Control Terminal port. While in the window session, only commands used to control the external device are recognized. IPX/IGX/BPX commands are not recognized. You might notice a slight transfer delay in transmission, due to the IPX/IGX/BPX bundling of characters before transmitting them. Transfers are delayed until the transfer buffer is filled, or until the keyboard has been inactive for over 50 milliseconds.
To end a window session, enter an escape sequence. Escape sequences are one-to-eight characters in length and are configured with the Configure Terminal Port Function (cnftermfunc) command. For example, if you have specified "signoff" as the escape sequence in the Configure Terminal Port Function, enter the following to end the window session:
The default escape sequence is:
If this escape sequence does not work and you do not know the configured escape sequence, leave the keyboard idle for four minutes. After four minutes, the system terminates the window session.
The sequences in Figure 4-3, Figure 4-4, Figure 4-5, Figure 4-6, and Figure 4-7 show the commands you execute to do the following node-related tasks:

Enables the MAJOR and MINOR alarm indicators on an Alarm Relay Card (ARC) or Alarm Relay Module (ARM) front card. It also configures the slot to provide external alarms from the Alarm Relay Interface (ARI) back card. This command should be used at each node equipped to provide external alarm indications to the customer alarm reporting system. The slot specified for the ARC or ARM may be any shelf slot but is usually the slot farthest to the right.
Upon command execution, the system places the alarm card set in the active state and displays the current alarm status.

Adds a trunk between a hub node and an interface shelf in a tiered network. The hub must be a BPX.
The interface shelf can be either an MGX 8220 shelf or an IPX node that Cisco has configured as an interface shelf. Because tiered network capability is a paid option, personnel in the WANBU TRT must telnet to the unit and configure it as an interface shelf before you can execute addshelf.
Each IPX/AF or MGX 8220 shelf has one trunk that connects to the BPX node serving as an access hub. A hub can support up to 16 T3 trunks to the interface shelves.
Before it can carry traffic, the trunk on an interface shelf must be "upped" (using uptrk) on both the interface shelf and the hub node and "added" to the network (using addtrk). When you execute uptrk, specify the STI header format and BPX Addressing Mode (BAM) mode. Also, a trunk must be free of major alarms before you can add it with the addtrk command.

Enables card redundancy for the IPX, IGX, and BPX cards. Use the addyred command to specify the slots of the primary and secondary (standby) cards that form the redundant pair. Refer to the section titled "Specifying Card Redundancy " at the beginning of this chapter for a list of supported card sets. Redundant card sets have the following characteristics:
In both the single and multi-port card sets, if the secondary card set becomes active, the primary card set serves as its backup (assuming the primary card set is complete and not failed). The addyred command can be used even if the primary and secondary slots are empty. If cards reside in the primary and secondary slots, the system checks for card compatibility. Two types of incompatibility can occur: back card and jumper or cable inconsistencies. (On SDI, FRI, and FTI cards, jumpers determine whether a port is configured as DCE or DTE. On LDI cards, either a DCE or DTE adapter cable connects to the LDI port. For descriptions of the jumper positions and cabling, see the Cisco IPX Installation manual or the Cisco IGX 8400 Series Installation manual.)
If incompatibilities exist, the message "Y-Cable Conflict" appears on the screen. Specific conflicts are listed in reverse video in the dspyred display. See the dspyred description for more information.

Configures the printing function. To obtain local or remote printing at a node, a printer must connect to the AUX PORT. Also, the configuration must include the correct baud rate and printer type for the port. Use the cnfterm and cnftermfunc commands to do this.
The cnfprt and cnftermfunc commands interact. If the auxiliary port on the node is configured for either an External Device Window or the Network Management Log, a "local" printing configuration automatically changes to "no printing." Printing is not possible because the auxiliary port is being used for another purpose.
Establishing a virtual terminal connection with a node does not affect the printing location established for the node that initiates the virtual terminal connection. For example, if node alpha is configured so that all alpha information goes to a printer at node beta and if alpha establishes a virtual terminal connection with node gamma, the results of print commands entered on the alpha keyboard still print at beta. Furthermore, this occurs regardless of the printing location configured for node gamma.

Configures data transmission parameters for the control and auxiliary ports. The IPX, IGX, and BPX nodes support two RS-232 serial ports on the upper bus expansion card. The top port is called the Control Terminal port. The lower port is called the Auxiliary Port (AUX). Parameters can vary with the equipment connected to the port. The control port may connect to a control terminal, a direct-dial modem, or an external RS-232 device. The auxiliary port may connect to either a printer or an external RS-232 device. Once the data transmission parameters have been set for a port, use the cnftermfunc command to specify the equipment attached to the port. The configuration parameters must match the equipment physically attached to the port.

use DTR | specifies whether the node requires DTR to be asserted to allow or maintain a Login. A "Y" causes the node to require the presence of DTR before allowing a login. A "N" causes the node to ignore DTR entirely |
Configures port functions for the IPX, IGX, or BPX control and auxiliary ports. The IPX and IGX nodes support two RS-232 asynchronous serial ports on the SCC and SCM, respectively. The BPX node supports two RS-232 asynchronous serial ports on the LMBCC. In all cases, the top port is the CONTROL TERMINAL port, and the lower port is the AUX PORT. Depending on the desired network configuration, the CONTROL TERMINAL port can connect to a control terminal, StrataView, a direct dial-in modem, or any external RS-232 device. The AUX PORT can connect to a printer, an auto-dial modem to call a control center, or any external RS-232 device.
The interface specified for the port must match the equipment physically attached to the port. The baud rate and other data transmission parameters for the port are set with the cnfterm command. If either port is configured as an external device window, enter the window command to begin a session with the external device.
If the auxiliary port is configured as an autodial modem, designate a "network ID" and a "phone number". Configuring the auxiliary port for an autodial modem enables the following to occur: When a change in alarm status happens anywhere in the network, the autodial modem attached to the auxiliary port dials the specified "phone number". If the call goes to the Cisco TAC, the alarm is logged under the specified "network ID". With this log, TAC engineers are automatically notified of any problems that occur on the network.

Any alarm status change in the network is automatically logged at the Cisco TAC using this network ID. Contact the Cisco TAC for the ID to use. |
dial string | Specifies the telephone number to be dialed when the network is reporting alarm status changes via the autodial modem. This parameter is valid only for "Autodial Modem" interfaces. The "phone number" can be up to 16 characters long and normally consists of digits and commas only. A comma is used to indicate that the autodial modem should pause two seconds before continuing to dial. For example, the number "9,4083700736" would cause the modem to dial a "9", pause two seconds, then dial the remaining digits. Contact the Cisco TAC for the number to use. |
Configures the time zone for the node. Configuring the time zone for a node ensures that the node's time is correct for the local area regardless of the node at which the network date and time are set. Once configured, the time zone for the node is saved in battery-backed memory. After a power failure, a node's date and time are restored if at least one other node in the network has the current time and date.

Deletes an interface shelf from a tiered network. The identifier for an interface shelf is either the trunk number of the name of the shelf. Normally, you execute delshelf only at the hub node, but on the IPX/AF itself, delshelf just lets you turn off LMI if the trunk is not allowing communication. In contrast to deltrk, you can execute delshelf at any time if no connections terminate at the trunk.

This command disables the Y redundancy for the card set in the specified primary slot number. If the secondary card slot is being used as the active slot at the time you use the delyred command, the system attempts to switch back to the primary slot. The substitution takes place only if the primary slot card set is complete and the cards are in a Standby or a Standby-F state (not if they are Failed). See the dspcds description for information on card states. See the addyred and dspyred commands for more information on Y-cable redundancy.

Displays BPX node alarms that, when active, produce an external alarm output (relay closure). These alarms are associated with powering and cooling the node as well as a statistics count. For example, a minor alarm is generated when a fan speed drops below 2000 rpm. Since the single ASM card is always located in slot 15, no card slot need be entered for this command. The ASM alarms are configured with the cnfasm command (SuperUser level)

Next Command:
Displays the cards in a shelf, front and back, with their type, revision, and status. For front and back card sets, the status field applies to the cards as a set. A letter "T" opposite a card indicates that it is running self-test. A letter "F" opposite a card indicates that it has failed a test. If lines or connections have been configured for a slot, but no suitable card is present, the display will list the missing cards at the top of the screen. If a special backplane is installed or if a card was previously installed, empty slots are identified as "reserved".
For an IPX 32 or IGX 32 node, the screen initially displays only the upper shelf with a "Continue?" prompt. Typing "y" to the prompt displays the cards in the lower shelf. The command dspcds followed by the letter "L" (for lower shelf) displays card status for just the lower shelf. For an IPX 8 or IGX 8 node, the card information appears in only the left column. The status and update messages are as follows:
♦ Active | Card in use, no failures detected. |
♦ Active—F | Card in use, failure(s) detected. |
♦ Active—T | Card active, background test in progress. |
♦ Active—F-T | Card active, minor failures detected, background test in progress. |
♦ Standby | Card idle, no failures. |
♦ Standby—F | Card idle, failure(s) detected. |
♦ Standby—T | Card idle, background test in progress. |
♦ Standby—F-T | Card idle, failure(s) detected, background test in progress. |
♦ Failed | Card failed. |
♦ Down | Card downed by user. |
♦ Down—F | Card downed, failure(s) detected. |
♦ Down—T | Card downed, failure(s) detected, background test in progress. |
♦ Mismatch | Mismatch between front card and back card. |
♦ Update * | Configuration RAM being updated from active control card. |
♦ Locked* | Incompatible version of old software is being maintained in case it is needed. |
♦ Dnlding* | Downloading new system software from the active PCC adjacent node of from StrataVIew Plus. |
♦ Dnldr* | Looking to adjacent nodes or StrataView Plus for either software to load or other software needs you have not specifically requested. |
In the preceding messages, an asterisk (*) means an additional status designation for BCC, NPC, or NPM cards. "F" flag in the card status indicates that a non-terminal failure was detected. Cards with an "F" status are activated only when necessary (for example, when no other card of that type is available). Cards with a "Failed" status are never activated.

Provides an interface to an external device. To establish a session with an external device, first use the cnftermfunc command to designate the port to serve as the external device window. To begin the session, enter the window command and specify the port. The control terminal screen subsequently clears, after which characters entered at the control terminal go to the external device and vice versa.
Because the IPX/IGX/BPX node "bundles" characters together before transmitting them, a slight transfer delay occurs. Transfers are delayed until the transfer buffer is filled or the keyboard is inactive for over 50 milliseconds. To end the session, enter the escape sequence designated with the cnftermfunc command. The default for the escape sequence is ^^ (SHIFT 66).
The window command can be executed over a virtual terminal connection. This makes it possible to control all external devices from a single point in the network.
