1370.0. "mibs problem with DC900/DC500" by ZPOVC::RAMARAJ () Fri Sep 02 1994 11:54

Cross posted in FDDI notes file and HUB_mgnt

Customer is running HP Openview Node Manager 3.3 on HPUX
DECconcentrator 500 and DECconcentrator 900 are on the network.
All digital mibs are from gatekeeper.dec.com

MIBs loaded include:
DEC-elan-v29
RFC1512

When doing system info is done, results are:

..dec.ema.15.5.1	- for DC500 V3.1
..dec.ema.15.5.4.1	- for DC900 V2.0

If in addition to the above mibs, DEChub90-v2 mibs are loaded the results are:

..dec.ema.emasystem.5.1		- for DC500 V3.1
..dec.ema.emasystem.5.4.1	- for DC900 V2.0

What other mibs are missing? and why is the DEChub90 mibs being used for
DC500 and DC900.

The concentrators show up on the map like ethernet devices on a straight line
instead of ring.

This is because the DEChub90 MIB contains a definition for emaSystem, while
the "DEC Vendor MIB" does not.

You've compiled a definition for emaSystem.  The definition came from
the DEChub90 MIB.  Openview is using this definition when decoding the
sysObjectID retrieved from the products.

This may be a small MIB consistency issue - but you've encountered the
full extent of the problem, that sysObjectIDs may be printed differently.
This would not lead to other problems (like the way devices are drawn on
maps).

The statement has nothing to do with anything previously mentioned.
I don't see how decoding a sysObjectID has anything to do with how a map
is drawn.  I suspect you'll have to tell Openview that the device is
an FDDI concentrator.  (It could figure this out by reading the FDDI MIB,
but I doubt it's that sophisticated.)

1370.2No such MIB.NACAD::GALLAGHERThu Sep 08 1994 14:1210
This question was answered off-line.

Raj asked how he could compile the definitions for the "15.5.1" and
"15.5.4.1" sysObjectID numbers.  My answer is that there should be
a MIB containing all the sysObjectIDs for all DEChub products, but 
there is not.  I mailed Raj a *very* rough draft of the DEChub 
sysObjectID's MIB which should help.  I don't expect to release the
MIB until after the next wave.
