Basically, when you discover the device in snmpc, is it that you discover the main administration module, or do you discover each VDC(Virtual Device Contexts) individually?
Environment
UIM 9.0 & later SNMPCollector 4.03
Cause
The ciscoVdcEntry MIB is not supported currently, with OID 1.3.6.1.4.1.9.9.774.1.1.1 in snmpc.
Resolution
It is working as designed. snmpcollector is not dynamic and we do not automatically discover or auto remove components.
