520.0. "GIGAswitch vs DH90 MIB definition problem?" by CAATS::MURRAY (Geoff Murray - CAATS Team - DTN 638-6925) Wed Nov 24 1993 22:28

    The GIGAswith MIB definition seems to conflict with both DEChub90 MIB
    definitions I have seen. The first DEChub90 MIB definition is the one
    that is distributed with MCC V1.3 (OpenVMS version). The second
    DEChub90 definition is an updated version available through the
    HUB_MGMNT conference (5-nov-1993 version).
    
    Extract from the DEChub 90 definition:
    
    	dec                     OBJECT IDENTIFIER ::=  { enterprises 36 }
    	ema                     OBJECT IDENTIFIER ::=  { dec 2 }
    	emaSystem               OBJECT IDENTIFIER ::=  { ema 15 }
    	bridges                 OBJECT IDENTIFIER ::=  { emaSystem 3 }
    
    Extract from the GIGAswitch definition:
    
    	dec             OBJECT IDENTIFIER ::= { enterprises 36 }
    	ema             OBJECT IDENTIFIER ::= { dec 2 }
    	sysobjid        OBJECT IDENTIFIER ::= { ema 15 }
    	bridges         OBJECT IDENTIFIER ::= { sysobjid 3 }
    	gigaswitch      OBJECT IDENTIFIER ::= { bridges 3 }
    
    Perhaps I am missing something about the way the DECmcc dictionary
    works. I have tried to add these both to the dictionary by using an
    AUGMENT, not REPLACE.
    
    I tried to add the DEChub90 definition after adding the GIGAswitch
    definition. It failed on the creation of the emaSystem portion. I
    believe it's because it's trying to give the same identifier value to
    two different names. 
    
    Is there a workaround for this? 
    
    I'm going to try editing the DEChub90 module and replace the emaSystem
    name with the sysobjid name, to see if it gets any farther. 
    
    Doesn't Digital have a registry for these values? Are these out of
    sync?
    
    Any help appreciated.
    
    Thanks,
    Geoff.

    I changes the emaSystem name in the DEChub MIB to sysobjid, to make it
    consistent with the GIGAswitch MIB. It seemed to compile, and I can see
    both sets in my MCC dictionary.
    
    Does anyone know which value is correct? emaSystem or sysobjid?
    
    Cheers,
    Geoff.

Geoff,

The DEChub90 definition "emaSystem" is incorrect.  I will notify the 
maintainers of this MIB so that it can be fixed in the next version.

Yes and yes.  In fact, the registry has "sysobjids" rather than "sysobjid".
I'll be working to resolve these discrepancies in the DEChub90 and DEChub900
MIBs.

Thanks for pointing this out.
