The key question is to ask the Tivoli/Cisco people which versions of the mosy 
compiler are being used.  NetView is notorious for always having the oldest 
version of the mosy compiler which gives the error messages you are seeing.

If you are creative, you can edit the Cisco mib .my file and correct the 
offender if you know what you are doing or simply comment out the entry if you 
don't.  In either case, NetView can then load the mib.
