This chapter provides you information on how to configure and invoke the Cisco StrataView Plus (SV+) 9.1 product. This chapter informs you how to:
The /usr/users/svplus/config.sv file contains a single line (or lines for more than one network or domain) of parameters used by Cisco SV+ to establish a connection to the BPX/IPX/IGX node at start-up. After both an upgrade and an initial installation, this file contains the default values (user configurable) /dev/ttya and 9600. Table 5-1 provides a list of a config.sv entry's 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. This field must not be changed. |
7 | 6 | Link retry count used by svmain. This field must not be changed. |
8 | 0 | Download throttling timeout value. This field must not be changed. |
9 | 30 | ACK timeout value used for download (configd). |
10 | 256 | Block size value used for download (configd). |
11 | 9.1 | Switch release version number. |
12 | nwip_on | Flag to indicate in-band (nwip_on/nwip_off) or out-of-band (lan_ip). |
For an initial (first time) installation of Cisco SV+, the default parameters gateway node name (Network1 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 Cisco SV+ to the attached network(s) or domains. Configure the workstation interface to the node LAN port as follows:
Step 1 You must be logged 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|9.1|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|9.1|nwip_on
Step 1 Contact your System Administrator to obtain IP addresses for your workstation and for the BPX/IPX 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 BPX/IPX 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 BPX/IPX 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|9.1|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 BPX/IPX 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 Cisco SV+ 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 Cisco SV+ workstation to an IPX or BPX 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 9.1 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 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 Cisco SV+ workstation and the BPX/IPX node to a LAN network. Examples are shown in Figure 5-1 and Figure 5-2. The LAN port on the BPX/IPX node provides a DB-15 connector for an AUI.
Step 10 To test that a LAN connection to the IPX/BPX 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 11 Once the workstation and BPX/IPX node interface are set up, you can start Cisco SV+. Following is a sample dsplan screen after Cisco SV+ was started and the communication sockets are active.

The Cisco SV+ Statistics Collection Manager (SCM) files for Cisco SV+ are installed as part of the Cisco SV+ installation. When multiple Cisco SV+ workstations are used to control the network, or when this is a structured network, you must upgrade each instance of Cisco SV+ and configure Cisco SV+ SCM on each Cisco SV+ workstation not running Cisco SV+.
Proceed as follows to configure the network for management by Cisco SV+ SCM.
1. Change directory to /etc:
host% cd /etc
2. When your workstation is not running NIS (yellow pages), edit the /etc/hosts file on the local Cisco SV+ workstation. For each node in the network to which this Cisco SV+ 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:
192.187.207.1 alpha
3. When your workstation is running NIS, follow step 2 on the NIS server workstation, instead of on the local Cisco SV+ workstation, and then remake the NIS maps.
4. Enter the following command to change back to the svplus directory:
host% exit
The first time Cisco SV+ is started, it obtains the current network topology information, and it also enables the default trunk and circuit line statistics you selected with the Cisco SV+ SCM software.
Before you invoke Cisco SV+, you must plan for the statistics types you want automatically enabled, and then enable them using the Cisco SV+ SCM program. Refer to the Cisco StrataView Plus Operations Guide for information on enabling statistics using Cisco SV+ SCM.
Invoke Cisco SV+ as follows:
Step 1 At the command line prompt, enter the following command to display the Cisco SV+ Main Menu:
host% SV+
Step 2 Select option 1 (Start Core) to start Cisco SV+.
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.
6. AT*FL0 - disables XON/XOFF flow control.
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.
