Monitor for unknown MAC addresses
Note: This example is provided as an illustration only and is not supported. Technical support
is available for the Context object, SNMP API, and scripting environment, but Ipswitch does
not provide support for JScript, VBScript, or developing and debugging Active Script
monitors or actions. For assistance with this example or with writing your own scripts, visit
the WhatsUp Gold user community (http://www.whatsupgold.com/wugspace).
This active monitor watches MAC addresses present on a network by polling an SNMPmanaged
switch and the bridge MIB. In the example script, you define a list of MAC addresses
you will allow to connect to the network. This monitor will fail if it finds devices that do not
match the addresses specified in the list.
// Modify the list below. It defines a list of allowed mac addresses with mapping to
switch interface
// on the network.
// This script will poll a managed switch using SNMP and the bridge MIB to detect MAC
addresses present
// on your network that should not be and to detect misplaced machines (connected to the
wrong port).
//
// The MAC addresses should be typed lowercase with no padding using ':' between each
bytes
// for instance "0:1:32:4c:ef:9" and not "00:01:32:4C:EF:09"
//
