Chapter 25 Configuring Your Computer for Desktop SNMP Services

Introduction

Enabling Desktop SNMP Services

Simple Network Management Protocol (SNMP) is an industry-standard protocol for communication between a network management console and the network devices that the console is to monitor. This chapter explains how to enable desktop SNMP services on your computer, and how to modify the NET.CFG file to implement additional SNMP options. The chapter is primarily for supervisors of networks in which an SNMP-based network management system is implemented.

Introduction

Through the SNMP agent provided with Personal NetWare(TM) , workgroups can be managed from Novell's NMS(TM) (NetWare Management System(TM) ), from other industry-standard SNMP management consoles, or from other third-party management systems.

Personal NetWare includes the following components:

Note that you require additional software running on a network management console to monitor the information collected by the SNMP agent, and you should refer to the documentation for that software to find out how to use it with the Personal NetWare agent.

Enabling Desktop SNMP Services

By default, desktop SNMP services are not enabled when you install the networking software. To enable desktop SNMP services, do the following:

1. At the system prompt, type 

SETUP <Enter>
2. Choose the Networking option.

3. Choose the <Network Management> button.

4. Select Load SNMP Agent, then save the changes and exit SETUP.

SETUP does the following:

5. Restart the operating system and answer Y to the following prompt:

Load Network Software (Y/N)?
NOTE: Personal NetWare network management support includes the files PNWTRAP.MIB and PNW.MIB; these files are needed on the network management console to enable the console to view the data collected at the desktop. The files are held in the directory C:\NWCLIENT. Refer to the documentation provided with the network management console to find out how to integrate the MIBs with the software on the console.

Setting the Time Zone Parameter

Use the DOS SET command at the system prompt or in a batch file to set the correct time zone for your area, as follows:

SET TZ = time_zone
If the time zone is not set in your computer's environment, traps for SNMP may report an incorrect time.

Configuring the HOSTMIB.INI File

The Host Resources MIB does not return information about devices attached to the host computers, such as printers, modems, and tape drives. If the network management console is to display details of such devices, you must list them in the HOSTMIB.INI file. This file is located in the directory to which you installed Personal NetWare (C:\NWCLIENT by default) on your computer. Use a text editor to enter a short description of each device. For example:

# Sample configuration file for HOSTMIB.EXE

# List of all printers connected to host

[printers]

HP LaserJet IIIp on LPT1:

#NEC P20 on LPT2:

# List of all modems connected to host

[modems]

Hayes Optima 144 on COM1:


# List of all tape drives connected to host

[tapes]

#Colorado DJ10

HP 35480A SCSI DAT (4-8 GB)

# other devices obtained via DOS APIs

Sample NET.CFG File for Desktop SNMP Services

 A sample of the NET.CFG for SNMP services is as follows:

Link Driver NE2000

PORT 300

INT 3

FRAME Ethernet_802.2

MEM D0000

Netware DOS Requester

USE DEFAULTS = ON

VLM = WSSNMP.VLM

VLM = WSTRAP.VLM

VLM = WSREG.VLM

VLM = WSASN1.VLM

VLM = MIB2IF.VLM

VLM = PNW.VLM

VLM = PNWTRAP.VLM

PREFERRED WORKGROUP = PN_WORLD

WORKGROUP NET = 04a23500:FEEEFFFFFFFF

PREFERRED SERVER = ENGINEERING

FIRST NETWORK DRIVE = F

NAME CONTEXT = ``OU=TECHSUPPORT''

DESKTOP SNMP

sysName = ``''

sysLocation = ``''

sysContact = ``''

snmpEnableAuthenTraps = ON

Enable Monitor Community = SPECIFIED

monitor community = ``public''

Enable Control Community = SPECIFIED

control community = ``public''

Enable Trap Community = SPECIFIED

trap community = ``public''

asynchronous timeout = 20

TRANSPORT PROVIDER IPX

trap target = 04a68900:00001b0ef8f8

trap target = 04a26700:00001b1e1ef8

TRANSPORT PROVIDER UDP

trap target = 123.123.111.111

trap target = 222.121.111.122

Conventional Memory Usage

 If you are willing to trade conventional memory for performance, you can load one or more Desktop SNMP VLM files in conventional memory.

NOTE: To load all VLM files in conventional memory, use the VLM /MC switch when running the VLM manager.

To load a Desktop SNMP VLM in conventional memory, place lines of the following form in the NET.CFG file:

Netware DOS Requester

VLM = VLMName.VLM

Load low VLMName = On
For example, to load Desktop SNMP while loading WSASN1.VLM and WSREG.VLM in conventional memory, place the following lines in NET.CFG:

Netware DOS Requester

VLM = WSSNMP.VLM

VLM = WSTRAP.VLM

VLM = WSREG.VLM

VLM = WSASN1.VLM

Load low WSREG = On

Load low WSASN1 = On

Where to Go from Here

 After you have completed the initial configuration of the desktop SNMP agent, you can modify the SNMP options in the NET.CFG file to meet your specific network requirements. Refer to the ``NET.CFG Options Reference'' chapter in DOSBook for a description of these modifications.
