Configuring Trap Destination
An easy-to-use Network Discovery Wizard guides you through the process of discover-
ing and mapping networked devices, including NJ200 Network Jack. The graphical
interface makes it easy to configure SNMP traps and alerts, monitor events, locate
devices, and troubleshoot problems.
When NJ200 Network Jack are discovered, 3Com Network Supervisor automatically
writes the trap destination (IP address of the management system) to them. This elimi-
nates the need to build a "Trap Destination Table" via a Management Information
Database (MIB) browser. (see Configuring SNMP Traps with a Third-Party Management
Platform section below).
Configuring 3Com Network Supervisor
The traps are attached to an item on the network map and are triggered when an event
occurs. The following event alerts can be delivered via e-mail, sound, pop-up message,
or by launching an application:
Cold Start
• indicates that the switch is down or disconnected
• Link Down indicates a problem in the cable or NIC
• Link Up indicates that the cable and NIC are functioning properly
Note: 3Com Network Supervisor does not support Authentication Failure traps or alerts.
With SNMP traps enabled and configured, IT staff can use 3Com Network Supervisor to
locate and identify network problems in three simple, point-and-click steps:
1. Receive an event alert.
2. Find the event in the Event List.
