This chapter provides information on how to configure and start the Cisco WAN Manager (CWM). This chapter includes information about:
This section provides information about configuring the CWM workstation to meet the needs of your network.
The config.sv file is located in the /usr/users/svplus directory. Each line of the config.sv file contains 12 fields of parameters used by CWM to establish a connection to the IPX/IGX 8400/BPX 8600 node at start-up. The default config.sv file contains a single line of data, shown below:
0|Network1|/dev/ttya|9600|0|7|6|0|30|1024|9.2|nwip_on|
After an initial installation or a software upgrade, the config.sv file will be overwritten with the default values. To establish a connection to the IPX/IGX 8400/BPX 8600 node at start-up, you must modify the config.sv file for your network. The config.sv file must have one line for each network the CWM workstation will manage.
Table 3-1 provides a list of the 12 parameters in the config.sv file.
| Field Number | Default Value | Description |
|---|---|---|
1 | 0 | Unique identifier for a network. |
2 | Network1 | Unique name for a network. |
3 | /dev/ttya | SV+ gateway node name/serial port. |
4 | 9600 | Serial port speed; must match the speed of the control port at the node. |
5 | 0 | Phone number to dial out (including prefix) if needed. 0 if not dialing out. |
6 | 7 | Link timeout value used by svmain. The amount of time to wait before resending a message to an IPX/BPX 8600 when a response is not received. This field must not be changed. |
7 | 6 | Link retry count used by svmain. The number of times CWM will retransmit a message before it declares the link down. This field must not be changed. |
8 | 0 | Download throttling timeout value. This field must not be changed. |
9 | 30 | ACK timeout value used during the download process. When an acknowledgment to a configuration message sent to an IPX, IGX 8400, or BPX 8600 is not received within this time period, the message is sent again. |
10 | 256 | Block size used for IPX, IGX 8400, or BPX 8600 configuration upload. |
11 | 9.2 | Switch release version number. |
12 | nwip_on | Flag to indicate in-band (nwip_on/nwip_off) or out-of-band (lan_ip). |
The 9.2 release of CWM contains the unique node ID feature which assigns a numerical identifier to each node in your network. The default value is TRUE, meaning that the CWM workstation will assign a unique node identifier to each network element as it is discovered.
If you want to use the Topology Configurator to assign the unique node ID to network elements, edit the Topod.conf file in /usr/users/svplus/config and change TRUE to FALSE on line four, then launch the Configurator and assign node IDs.
Following is the default Topod.conf file:
# Set the Debug Level Debug Level 4 # AutoNode Id Generation Flag AutoNodeId TRUE # No of Children to be started by topod Children linktopoc filetopoc # No of Core Clients Core emsd rtm eventd
For an initial (first time) installation of CWM, the default parameters gateway node name (/dev/ttya in the example shown below) and baud rate (9600 in the example shown below) are not applicable. You must modify the /usr/users/svplus/config.sv file to set up the required links from CWM to the attached network(s) or domains. Configure the workstation interface to the node LAN port as follows:
Step 1 Log in as user svplus.
Step 2 Modify the network configuration value in the /usr/users/svplus/config.sv file by changing the third field's contents to the node's LAN port hostname. Following is an example of a /usr/users/svplus/config.sv default entry:
0|Network1|/dev/ttya|9600|0|7|6|0|30|1024|9.2|nwip_on
Modify the third field to your gateway node's name (maximum length is eight characters), for example sanfran, as shown in the following example:
0|Network1|sanfran|9600|0|7|6|0|30|1024|9.2|nwip_on
Step 1 Contact your System Administrator to obtain IP addresses for your workstation and for the IPX/BPX 8600 node you are going to configure.
Step 2 Normally, the System Administrator updates the NIS database (if NIS is used), and adds the IP addresses for the workstation and IPX/BPX 8600 node to the NIS database.
When your System Administrator is responsible for the addressing of the workstation, as well as the /etc/services file, proceed to step 3. If not, and NIS is not being used, do the following:
Edit your workstation's /etc/hosts file by adding the following lines, if they do not already exist, to this file. Note, the addresses shown are just examples. Use the addresses obtained from your System Administrator. (This example is for a workstation named "hedgehog" at address 192.187.207.200. It also assumes the IPX/BPX 8600 LAN port for node "sanfran" has been assigned an IP address of 192.187.210.30, and a hostname of sanfran. Your own host name and addresses will be different.)
192.187.207.200 hedgehog
192.187.210.30 sanfran
Step 3 Edit your workstation's /etc/services file, and add the following entry:
IPX_PORT 5120/tcp ipx_port
Step 4 Reboot the workstation so the modifications to the /etc/services file take effect.
Step 5 Modify the /usr/users/svplus/config.sv file for the network configuration by changing the third field to the node's LAN port hostname, for example, "sanfran" as follows:
0|Network1|sanfran|19200|0|7|6|0|30|256|9.2|nwip_on|
Leave the other fields unchanged. Note, the baud rate of 19200 does not apply to a LAN connection.
Step 6 Configure the LAN port on the IPX/BPX 8600 node using a dumb terminal or an RS-232 connection via the workstation (using the vt command, as applicable) to enter the appropriate cnflan parameters.
The cnflan command configures the node's communication parameters so the node can communicate with a CWM terminal, over an Ethernet LAN, using the TCP/IP protocol. These parameters contain address information about the Ethernet TCP/IP network that is used to connect the CWM workstation to an IPX or BPX 8600 node. The values must conform to those of the network and should be supplied by the Ethernet network administrator.
The cnflan command has the following parameters:
sanfran LAN Cisco/StrataCom IPX 32 9.2 Apr. 27 1998 14:23 PSTActive IP Address: 192.187.207.21IP Subnet Mask: 255.255.255.0TCP Service Port: 5120Default Gateway IP Address: 192.187.207.1Maximum LAN Transmit Unit: 1500Ethernet Address: 00.55.43.00.04.55Control Socket - ReadyBase Socket Descriptor - 1Socket ClosedLast Command: cnflanNext Command:Step 7 Set all eight switches on the switch module on the NPC to ON (switches toggled toward the edge of the card). The OFF setting is for a serial connection.
Step 8 Connect the CWM workstation and the IGX/BPX 8600 node to a LAN network. Examples are shown in Figure 3-1 and Figure 3-2. The LAN port on the IPX/BPX 8600 node provides a DB-15 connector for an AUI.
Step 9 To test that a LAN connection to the IGX/BPX 8600 port is okay (for example, for the hostname "sanfran" entered in the /usr/users/svplus/config.sv file), type the following at the command line prompt:
host% /usr/sbin/ping sanfran

Step 10 Once the workstation and IPX/BPX 8600 node interface are set up, you can start CWM. Following is a sample dsplan screen after CWM was started and the communication sockets are active.

The CWM Statistics Collection Manager (SCM) files for CWM are installed as part of the CWM installation. When multiple CWM workstations are used to control the network, or when this is a structured network, you must upgrade each instance of CWM and configure CWM SCM on each CWM workstation not running CWM.
To configure the network for management by CWM SCM, complete the following steps:
Step 1 Change directory to /etc:
host% cd /etc
Step 2 When your workstation is not running NIS, edit the /etc/hosts file on the local CWM workstation and create the an entry like the following:
host# 192.187.207.1 alpha
For each node in the network to which this CWM SCM is to connect, create an entry containing the node name and IP address.
Step 3 When your workstation is running NIS, follow step 2 on the NIS server workstation, instead of on the local CWM workstation, and then remake the NIS maps.
Step 4 Enter the following command to change back to the svplus directory:
host# exit
The first time CWM is started, it obtains the current network topology information. CWM also enables the default trunk and circuit line statistics you selected with the CWM SCM software.
Before you launch CWM, you must plan for the statistics types you want automatically enabled, then enable them using the CWM SCM program. Refer to the Cisco WAN Manager Operations guide for information on enabling statistics using the Cisco WAN Manager's SCM.
Launch CWM as follows:
Step 1 At the CWM workstation, login as user svplus and launch a CDE session on the workstation.
Step 2 At the command line prompt, enter the following command to display the CWM Main Menu:
host% CWM
Step 3 Select option 1 (Start Core) to start the CWM core.
Refer to the Cisco WAN Manager Operations guide for detailed information about starting CWM from a powered off workstation or performing a warm or cold start of CWM.
The following commands are used to configure a Codex V.34 RSA modem.
Using the cnfport command, set the IPX Control port (CONTROL TERMINAL port) to 9600 bps and disable XON/XOFF flow control. Using the cnfportfunc command, set the terminal type to VT100/StrataView. To program the modem, temporarily attach a terminal to the modem using a 25-pin straight through cable. The modem EIA port will automatically match the 9600 bps setting of the terminal. Enter the following commands:
1. AT&F - reset to factory default and save.
2. ATSØ=1 - enables Auto-Answer Mode (answer on first ring).
3. ATL1 - modem speaker at low volume.
4. AT*SM3 - enables automatic MNP error correction.
5. AT*DC0 - disables data compression.
6. AT*FL0 - disables XON/XOFF flow control.
7. AT&S1 - sets DSR to "normal".
8. ATE0 - disables local character echo.
9. ATQ1 - disables result codes. (Modem will appear "dead".
10. AT&W - saves current configuration settings in non-volatile memory.
Connect the workstation to the modem, with the serial port set to 9600 bps, using a 25-pin straight-through cable (uses RS-232 protocol), then enter the following commands:
1. AT&F - initializes factory defaults.
2. ATL0 - modem speaker at low volume.
3. AT*SM3 - enables automatic MNP error correction.
4. AT*DC0 - disables data compression.
5. AT*SC1 - enables DTE speed conversion.

7. AT&C1 - DCD controlled by modem.
8. AT&D2 - Modem disconnects when IPX toggles DTR.
9. AT&V - verify entries.
10. AT&W - saves current configuration settings in non-volatile memory.
Customer Service provides support for your CWM workstation via a dial-up modem connection. This support is available when a Motorola Codex modem is provided at your site. You must perform two procedures before the Customer Service can dial into your CWM workstation.
1. Configure the selected workstation's serial port to emulate a VT100 terminal.
2. Configure the Codex modem EIA leads for the workstation.
The following information describes how to set up a dial-in connection. These procedures are for a typical connection. Refer also to the applicable Sun SPARCstation System Administration User's Guide, and the Codex V.34 RSA Modem User's Guide.
Step 1 Log in as root.
Step 2 Enter the following command to start System Administration Manager (SAM):
# sam
The System Administration Manager window appears.
Step 3 Double-click the Peripheral Devices icon. The SAM Areas for Peripheral Devices window appears (Figure 3-3).
Step 4 Double-click the Terminals and Modems icon. The Terminals and Modems window appears.
Step 5 Set up a new modem as follows:
(a) From the Actions menu, select Add Modem. The Add Modem window appears (Figure 3-4.)
(b) Modify the settings to suit your environment.
Step 6 Modify the settings of an existing modem as follows:
(a) Select the modem for to modify.

(c) Modify the settings to suit your environment.
To configure the modem to receive incoming Cisco Customer Service according to the Auto-Answer procedure, follow the procedures in "Auto-Dial (V.34 Modem)".
Some of the modem EIA leads are not supported by the workstation.
If you are using a Hayes modem, enter the following AT commands.
DCD---On | AT&CØ |
DTR---On | AT&DØ |
DSR---Normal | AT&S1 |
CTS---ON when connected | AT&R1 |
| ATSØ=1 (answer on first ring) |
When the system is up, Cisco Customer Service can connect to the CWM workstaton via the workstation's serial port.
The following sections describe changes required to file systems. All of these changes should be done as root user.
Edit the /etc/hosts file to add IP addresses and mnemonics. For node LAN IP address, enter the following:
123.45.67.201 <tab> igx2-lan
For IP-relay addresses, enter the following:
100.100.100.1 <tab> igx2
Edit the /etc/rc.config.d/netconf file to add routes and to enable routing when the workstation is booted.
Using vi (or another text editor), find the section in the netconf file labeled Internet Routing Configuration, and add the following five lines to the netconf file:
ROUTE_DESTINATION[1]=10.10.10.1After completing the configuration, reboot the workstation.
# sync; sync; syncConfigure the modem connected to the workstation according to the Auto Answer procedure.
1. AT&C0 - DCD on.
2. AT&D0 - DTR on.
3. AT&S1 - DSR normal.
4. AT&R1 - CTS on when connected.
5. ATS0=1 - answer on first ring.
When the workstation is running, Cisco Customer Service is capable of calling into the CWM workstation's serial port.
To start the CWM Desktop from a remote workstation, complete the following steps:
Step 1 Open a terminal window.
Step 2 Enter the following at the command line prompt:
host% xhost <CWM_host-workstation-name>
Step 3 rlogin or telnet to the CWM 9.2 host workstation.
Step 4 Set the DISPLAY environment variable for a local display.
For example, where the local workstation is named "maui":
Using csh: setenv DISPLAY maui:0.0
Using sh: DISPLAY=maui:0.0; export DISPLAY
Step 5 Enter the following at the command line prompt:
host% cd /usr/users/svplus
Step 6 Start the CWM 9.2 program:
