Unknown Traps

This documentation applies to NMS version 5.4. An online version of the software can be found here.

The Unknown Traps page displays the SNMP traps SevOne NMS receives for which you do not define a trap event. Simple Network Management Protocol traps are an aspect of SNMP that enables a device to send information. An example of a trap trigger is when a new interface is added or a device is restarted. The traps that appear on the Unknown Traps page are less meaningful than traps for which you define a trap event. Trap events enable you to assign real meaning to SNMP traps. The goal is to enable you to define trap events (either ignore, log, or alert) for the traps that are specific to your environment. The Cluster Manager Cluster Settings tab enables you to define how many days to save unknown traps.

To access the Unknown Traps page from the navigation bar, click the Events menu, select Archive, and then select Unknown Traps.
