Configuring and Starting
Cisco WAN Manager 9.2

This chapter provides information on how to configure and start the Cisco WAN Manager (CWM) 9.2 product. This chapter includes information about:

Configuring the Cisco WAN Manager Workstation to Your Network

This section provides information about configuring the CWM workstation to meet the needs of your network.

Modifying the config.sv File

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|256|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 5-1 provides a list of the 12 parameters in the config.sv file.


Table 5-1: config.sv Parameters
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).

Note The name of the gateway node specified in the config.sv file must be the same as the name of the node configured on the switch. When the IP address of the node is specified, ensure the name resolves to the node name configured on the switch by issuing a ping command using the name assigned with the Node ID Editor.

Editing the Topod.conf file

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
Note The other lines is the Topod.conf file should not be modified.

Configuring Cisco WAN Manager for a LAN Connection

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

Note You must create a separate entry for each network. For example, when three networks exist, you must create three separate entries. The second field in each entry, network name, identifies a particular network (for example, "Network1", "Network2", and "Network3"). Each entry's eleventh field contains the Cisco switch version number (9.2). You do not need to modify any of the entry's other fields.

Configuring the Cisco WAN Manager Workstation for a IPX/BPX 8600 LAN Port

Note You must configure the IPX/BPX 8600 node's LAN parameters before connecting it to a LAN.

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

Note 5120 is used for the LAN ports on all IPX/BPX 8600 interfaces and must never be changed.
Note When NIS is used, which is not generally the case, you should contact your System Administrator.

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 PST
Active IP Address: 192.187.207.21
IP Subnet Mask: 255.255.255.0
TCP Service Port: 5120
Default Gateway IP Address: 192.187.207.1
Maximum LAN Transmit Unit: 1500
Ethernet Address: 00.55.43.00.04.55
Control Socket - Ready
Base Socket Descriptor - 1
Socket Closed
Last Command: cnflan
Next Command:

Step 7 Verify the IPX node contains an SCC-B backcard and an NPC card (required for LAN connection to IPX).

When the node is an IPX 8 or 16 single shelf unit, verify the utility bus has been upgraded to a UBS-2, model 550058. Refer to the IPX Reference Manual for further information on upgrading these components.

Step 8 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 9 Connect the CWM workstation and the IPX/BPX 8600 node to a LAN network. Examples are shown in Figure 5-1 and Figure 5-2. The LAN port on the IPX/BPX 8600 node provides a DB-15 connector for an AUI.

Step 10 To test that a LAN connection to the IPX/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

Figure 5-2: Cisco WAN Manager LAN Connection to an IPX Node (No Gateway)


Step 11 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.

Note Sockets describe the UCB/BSD end point of a communications connection. For CWM, this is a TCP/UDP connection.

Configuring Statistics Collection Manager

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.

Note For detailed information on how to install a Stand-alone version of SCM, see Chapter 6, "Statistics Collection Manager Stand-alone Installation Procedures".

Proceed as follows to configure the network for management by CWM SCM.

    1. Change directory to /etc:
    host% cd /etc

    2. When your workstation is not running NIS, edit the /etc/hosts file on the local CWM workstation. For each node in the network to which this CWM SCM is to connect to, create an entry containing the node name and its IP address. For example, to add an IPX node named "alpha", whose IP address is 192.187.207.1, you would create the following entry in the /etc/hosts file:

    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.

    4. Enter the following command to change back to the svplus directory:
    host% exit

Initial Start-Up of Cisco WAN Manager

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.

Prerequisites

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.

Start-up Procedure

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.

Note Two messages may appear during the initial part of the CWM start-up process: "IPC: connect failed: Connection refused" and "svmain: L4 send to Application Layer failed." These messages indicate a temporary condition and may be ignored. If these messages continue to be displayed, call Customer Service.

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.
