If traps aren't being properly sent from your SNMP device, they obviously won't make it to their destinations. Your SNMP device may have a debug mode option. Once in debug mode, you will see a display of traps being sent out by the device. By creating events at the site and watching the debug-mode trap display, you can determine whether traps are trying to be sent. Remember that you may need to reconfigure the remote to send a trap in response to the event you're generating. DPS Telecom remotes can be configured to send traps on a point-by-point basis.
Another testing method is to look for a coldstart trap following a bootup. Power cycle your device and watch for the trap that, on many SNMP devices, is sent when booting. Check your device documentation to ensure that you don't waste time looking for a coldstart trap that your device isn't designed to send.
If traps are not being sent, you have an issue with your SNMP device. If they are being sent, check your network setup, firewalls, MIB files, and trap formats using the other sections of this guide.
If you have a NetGuardian RTU, you can easily verify that it is sending traps correctly:
