ActiveXperts Network Component SnmpManager Object

SNMP stands for Simple Network Management Protocol. Simple Network Management Protocol is a set of standards for communication with devices connected to a TCP/IP network. It is often used to communicate with hubs and switches.

Since it was developed in 1988, the Simple Network Managment Protocol has become the de facto standard for network management. Because it is a simple solution, requiring little code to implement, vendors can easily build SNMP agents to their products. SNMP is extensible, allowing vendors to easily add network management functions to their existing products. SNMP also separates the managment architecture from the architecture of the hardware devices, which broadens the base of multivendor support. Perhaps most important, unlike other so-called standards, SNMP is not a mere paper specification, but an implementation that is widely available today.

Network Component is compliant with SNMP v1 and SNMP v2c. Network Component automatically detects which SNMP version is running on the remote agent and adapts to it.

The Network Component SNMP object supports different data types, including:

The Network Component Snmp object defines the following operations:

The SnmpManager object is part of the Network Component. Overview of all Network Component objects:

DnsServer & DnsRecord - Ftp & FtpFile - Http - Icmp - IPtoCountry - Msn - Ntp - Radius - Rsh - Scp - SFtp - Ssh - SnmpManager - SnmpTrapManager - SnmpMibBrowser - Tcp - Tftp - TraceRoute - Udp - Xen - Wake-on-LAN - Xen (Citrix)

SnmpManager Sample code

VBScript sample: SNMP Get

   Set objManager = CreateObject("AxNetwork.SnmpManager")


   objManager.Open "server03", "public"
   If( objManager.LastError <> 0 ) Then
   End If

   Set objSnmpObject = objManager.Get( "system.sysDescr.0" )
   If( objManager.lastError = 0 ) Then
     WScript.Echo " OID  : " & objSnmpObject.OID
     WScript.Echo "Value : " & objSnmpObject.Value
     WScript.Echo "Type  : " & objSnmpObject.Type
   End If

Visual Basic .NET sample: SNMP Walker

Imports AxNetwork

Module Module1
    Sub Main()
        Dim objManager As SnmpManager = New SnmpManager
        Dim objSnmpObject As SnmpObject
        Dim strOID As String = "system.sysDescr.0", strNextOID As String

        objManager.Open("dell03", "public")
        If (objManager.LastError = 0) Then
            objSnmpObject = objManager.Get(strOID)
            While (objManager.LastError = 0)
                Console.WriteLine(objSnmpObject.OID + " : ")
                Console.WriteLine(" Value:" & objSnmpObject.Value)
                Console.WriteLine(" Type:" & objSnmpObject.Type)
                objSnmpObject = objManager.GetNext()
            End While
        End If
    End Sub
End Module

On, you can find a lot of Network Component samples. These samples are also part of the Network Component installation.
