Trap Source Overview

During installation, you indicated whether NerveCenter should be configured to support SNMP v3. Depending on your answer, your platform, and whether OpenView Network Node Manager is coresident on your system, your trap source is one of the following:

When NerveCenter is your trap source, NerveCenter uses the port specified on the Ports tab for capturing traps. This value, SNMP Trap port, is 162 by default. If you want NerveCenter to capture traps, this port must be free for NerveCenter to capture the traps.

During installation, if you selected SNMP v3 support in NerveCenter, you were asked to disable MSTrap or OVTrapD service on your system so that the trap port (162) would be free for NerveCenter to use.

After installation, you can change the trap source in NerveCenter Administrator. Keep in mind that neither MSTrap nor OVTrapD support SNMP v3.

Following are the types of traps supported by the trap engines:

• OVTrapD: SNMP v1 and v2C traps
• MS Trap Service: SNMP v1 traps
• NerveCenter: SNMP v1, v2C, and v3 traps

To manage SNMP v3 traps, you must use NerveCenter as a trap source.
