Does SCOM 2012SP1 able to discover SNMPv3 device and receive SNMPv3 traps? I can't get the discovering work for my IBM datapower appliances.

Hi,

SNMP v3 devices can only be discovered by explicit discovery or by being specified in a recursive discovery rule. If you specify an SNMP v3 device in a recursive discovery rule, the SNMP v3 device will be discovered but devices connected to it will not be discovered.
