SNMP MIB Browsing in VBScript

ActiveSocket provides an easy-to-use development interface to a variety of IP protocols. By using ActiveSocket, you can very easily create or enhance applications with network features.

ActiveSocket features the following: ICMP, TCP, UDP, HTTP and HTTPs with support for proxy servers and secure web sites, DNS, Telnet, NTP time protocol, SSH Secure Shell, RSH remote shell script interface, SNMP (Simple Network Management Protocol), SNMP Traps, SNMP MIB Browser, Sockets, WOL (Wake-On-LAN), IP-to-Country and more.

SNMP MIB Browsing can be well integrated into VBScript environments.
This document describes how ActiveSocket's SNMP MIB Browser can be integrated into VBScript projects.

A management information base (MIB) is a database used to manage the devices in a communications network. The database is hierarchical (tree-structured) and entries are addressed through object identifiers (OID's). A MIB should contain information on these commands and on the target objects (controllable entities or potential sources of status information) with a view to tuning the network transport to the current needs. Each type of object in a MIB database has a name, a syntax, and an encoding. The name is represented uniquely as an OID. An OID is an administratively assigned name. The administrative policies used for assigning names are discussed later in this memo.

Use ActiveSocket's 'SnmpMibBrowser' object to load a MIB database into memory and iterate over all objects and view all properties.

Step 1: Download and install the ActiveSocket Toolkit

Download ActiveSocket from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create a new script

Create a new script using your favorite editor. You can simply use notepad. However, a VBScript editor is recommended, so you can browse through objects, objects properties and object functions.

You're now able to write a more advanced script to communicate using the ActiveSocket Toolkit.

Step 3: Create the ActiveSocket object in VBScript

Create a new VBScript file called DEMO.VBS. It is recommended to insert the following line on top of your code:

   Option Explicit

This statement requires that all variable names be defined (with the Dim statement), to avoid simple typos that can cause incredible headaches and long debugging sessions for something that should have never happened.

Now, declare the ActiveSocket object(s):

   Dim objSnmpMib

Create the ActiveSocket object(s) like this:

   Set objSnmpMib     = CreateObject( "ActiveXperts.SnmpMibBrowser" )

Now, add the following lines to the file to have your fist ActiveSocket VBScript program:

   WScript.Echo "Version: " & objSocket.Version
   WScript.Echo "Expiration Date: " & objSnmpMib.Expiration Date

There are many working samples included with the product. You can also find them on the ActiveXperts FTP site: ftp.activexperts-labs.com/samples/asocket.

The ActiveSocket tool is a Network Communications ActiveX software component (SDK).
