This is frustrating... trying to import CISCO-ENTITY-SENSOR-MIB

Question

Well, really trying to import CISCO-ENTITY-SENSOR-EXT-MIB in order to process traps from ASA with "snmp-server enable traps entity power-supply-failure" configured. Figures that CISCO-ENTITY-SENSOR-MIB is a prerequisite. After painstakingly loading up the MIB dependencies listed at http://tools.cisco.com/Support/SNMP/do/BrowseMIB.do?local=en&step=2&mibName=CISCO-ENTITY-SENSOR-MIB, it fails at the last juncture with
CISCO-ENTITY-SENSOR-MIB itself:

Those three allegedly missing MIBs are right there in the same directory, and have been imported earlier (though some had no "translation"):

What am I missing?

Answer 1

I've successfully tried to stay clear of this type of thing as much as I could so my response might be silly.
But one of the things I recall was that a 'somemib.my' file needed 'thatothermib', that was actually there in the directory as 'thatothermib.my', just like I downloaded it, but the mibcompiler was smart enough to look for 'thatothermib.mib'.
Not sure if is was referenced in the other mibfile with a specific extension of if it was the compiler trying to stop me.
Never understood how they managed to make something so simple so complicated.
Cheers,
