Scenario: White List is set up but you want real-time or near real-time alerts when a rogue device connects to the network.

Set up your devices to send connection-related traps to the UDT server. UDT checks the database for trap-related information at set intervals. If an endpoint connects to a UDT device, and the endpoint is not on the White List, UDT posts an alert in the Web Console.

  • The following instructions are for Cisco devices only.
  • You can remove device configurations by running a given command with no in front of it. For example, no set logging server ip_address removes that target from the remote logging stream.

To enable your Cisco devices to send trap messages:

  1. Open a command line in config mode on your device.
  2. Execute the commands from the examples, changing the IP address to match your UDT server.

    Traps (IOS)

    snmp-server host public config

    snmp trap mac-notification change added

    snmp trap mac-notification change removed

    Traps (CatOS)

    set snmp trap public config

    snmp trap mac-notification change added

    snmp trap mac-notification change removed

  3. Open the UDT Settings on the UDT server (Settings > UDT Settings).
  4. Click Advanced Settings.
  5. Enter a value (in seconds) under MAC Notification Processing Inverval for the frequency with which you want UDT to check for new trap messages.
  6. Click Save.
  • To verify your setup, connect a device to the network that is not on the UDT White List.
  • Wait for the time you allotted in Step 5, and then check the Active Alerts and All Triggered Alerts resource for an entry that shows the MAC address of the device you just connected.
