Issue:
Can not discover Servertech PDU in StruxureWare DCE using SNMP version 3

Product Line:
StruxureWare Data Center Expert (DCE)
- Basic Appliance (AP9465)
- Standard Appliance (AP9470)
- Enterprise Appliance (AP9475)
- Virtual Appliance (AP94VMACT)
StruxureWare Central (SWC)
InfraStruXure Central (ISXC)

Environment:
ISXC, SWC, & DCE (potentially any version)
Servertech PDU (CW-24VYM311A1, potentially others)

Cause:
Potential configuration issues on the Servertech PDU may prevent device discovery using SNMPv3 if authentication is set.

Resolution:

During discovery in Data Center Expert, it was seen that changing the "trap type" on the PDU to snmpv3 allowed DCE to discover the device.
NOTE: During discovery of 3rd party devices, the priority scanning" option should be unchecked.
