5679.0. "DECnis and FRBS channel counters" by MUNICH::FERSTL () Thu Oct 21 1993 14:44

Hi,

I have a customer who searches for a simple method to collect information 
about the workload of the FRBS channels of his DECnis 500 (V2.2.4).

He tried to show the FRBS channel counters in graph modus. But he has 
problems with it, because MCC doesn't display fields like "Frames Sent",
"Octets Sent", "Frames received"... for the counters.
Instead you can find fields "Attribute Code 40", "Attribute Code 41"...
as you see it below.

Is there an explanation? 
How can the customer collect information about the workload of his lines?
He says there's nowhere the possibility to do a "SHOW STATISTICS".
                                                                         
I'm not able to reproduce the problem in my office, because we haven't set
up our DECnis to use PPP and FRBS connections.

    
Thanks for any help

A quick look into the dictionary under 'class node subclass frbs
subclass channel' showed me that the attributes in question are simply
not defined. Please escalate the problem through the proper channels. If
it's just a matter of defining the attributes it shouldn't be too hard
to fix. A sample of the NCL output would surely help the engineer to 
figure out which is which, without having to install a DECnis.

When 1.3 went out, the dictionary was current.

The problem is that the management specifications for the DECnis
is an ever moving target.  The development engineers keep changing/adding
to the definitions for the various objects.  They have good reasons to, 
I'm sure.

The problem is that they check in their changes in their source code, and
some time later, they update the DSSR, but that does not get anything
that is anywhere near current for the dictionary in MCC.

Think of MCC as a "C" compiler.  You went out and bought an application
from a third party written in "C", and when there is a bug in the 
application code, you now expect the compiler developer to provide the patch.

Frameworks (MCC) is not going to be providing updates for the dictionary
for quite some time.  So, I guess you should get the MSL updates for the 
current rev of the DECnis from the engineering group that is building it.  
Then you might just have a chance of being current.

 

DECNIS is no different from any other EMA-managed entity.

I would dispute the order :-).  Suffice it to say that the DSSR registration
requests are completed before the changed DECNIS code submits to the SSB.

But we  don't  have  the  *MCC* MSLs! We do ship (and install) the necessary
*NCL*  dictionary  updates but we rely on MCC releasing fairly frequently to
get  updates  into  the  MCC dictionary.  That was the process agreed a long
time ago between me, Bob Lynch and Wally Matthews.

If there  has been a change in policy which means that MCC won't be shipping
dictionary updates "for quite some time" then you need to work with DSSR and
all  the people shipping products (including DECNIS) to make sure that there
is  a mechanism for them to ship dictionary updates on their kits (including
a  supported  mechanism  for  getting  those  updates  into  the  customer's
dictionary).    The   DECNIS   development   manager   is   Ken  Chamberlain
(MARVIN::KCHAMBERLAIN).

Well, that's what I suspected. Anyway, I escalated the problem against 
MCC and hope that it will eventually flow into the right channel. In the 
meantime - do you know a name in the DECnis group whom I could contact?
