Subj: GLAXO Customized Implementation of DECmcc SMS Trip Report
1. Introduction
----------------
Glaxo is a pharmaceutical company in North Carolina, and a large
Digital account. They use a variety of Digital products from Terminal
Servers and workstations to VAX 9000 and FDDI products.
Their network in US could be described as a large extended LAN.
Almost all of their LANs are connected together via Bridges (LAN
Bridge 100, 150 and 200s; plus few Vitalinks) and about 70% of their
traffic is LAT.
The purpose of this project, was to install and customize
DECmcc SMS for Glaxo, and to demonstrate the tools capabilities
in management of their network.
This report consists of 4 sections:
Section 1: Introduction
Section 2: lists the items completed at customer site
Section 3: provides a summary list of problems and customer feedback
Section 4: discusses the detail of problems and feedbacks
2. ACCOMPLISHMENTS:
-------------------
. Initial Project Kick-off meeting
. Met with Glaxo's senior network manager and discussed the current
GLAXO network environment. (Discussed topics such as: Network
topology, Current Traffic, DNS setup, Current Namespace, New server,
Network entities to be managed, desired domain layout, domain names,
what to monitor, what problems to look for, etc).
. Checked, verified and set the system requirements, for SMS, DNS,
Datatrieve, Rdb, CDD, and DECgraph, on the network management system.

3. Summary of Problems & issues:
--------------------------------
Following is the list of customer's issues & concerns and the
problems which occurred when installing and setting up DECmcc at Glaxo.
This list is not in any particular order. Some are problems that were
resolved (not without pain!), some are issues that are known problems,
and others are customer feedback.
My goal was to present the difficulties and raise the customer concerns
that will likely be raised again by other customers.
Please note that these were the initial issues and problems. After
using the product for longer period of time, the customer might have
other concerns and comments.
I like to thank Ray Paquet and Stella Ko for their support while
I was at the customer site.

4. Detail of Issues & Problems:
-------------------------------
1 - DNS: Inflexibility of location of MCC directories
Problem Introduction: The first 4 problems are DNS related. However
the customer looks at it as "Digital problem".
We are promoting a "Distributed Management System".
The customer is paying for that, and does not care
whether it is MCC problem or DNS problem. We need
to solve our problems internally, especially that
MCC use of DNS is the right answer.
Problem Background: The customer already had DNS.
They had one Namespace, 2 servers, and
2 clearinghouses. We planned on installing a 3rd server
(3rd clearinghouse) on the DECmcc system, so the
Iconic map always be available. In addition, we used
the current Namespace.
Problem Detail: They had a DNS naming plan/structure, and wanted to
maintain that. (At the root only one directory -
.Glaxo - One directory under that, for each country -
.GLAXO.US, .Glaxo.UK , etc). They wanted me to put
all the MCC directories under the .GLAXO.US But I
had to tell them that the only ones that I could put
there are .DNA_NODE and .MCC directories. The
DNA_NODESYNONYM and the BACKTRANSLATIONs have to be
at the root.
They were not very pleased with that!
Note: I must state that I do not have a definite answer
yet as to which directory can be where. I have asked
several people, and the above was the best answer
I received. It would be helpful if this info
was confirmed, and documented so everyone could
use it in their Namespace planning.
2 - DNS: Access control problem
Problem detail: MCC_DNS_SETUP failed with access control problem, even
though "mccnod::DNS$SERVER" was granted access to the root.
In DNS (MCR DNS$CONTROL); the command
DNS> SHOW ACCESS DIR .
begun showing the access for different Entries, but
after showing a few, DNS would fail, and would return to
the $ prompt.
Problem Cause: After troubleshooting this for a while it turned out that
when DNS manager added the required Access for
MCCNOD::DNS$SERVER, he must have had a typo, or something!!
DNS however accepted whatever was inputted, but then when
list the "access" for the root, it would fail (/crash!).
Problem Solution: This is a DNS known problem.
Had to remove access & add it again.
3 - DNS: Registration problem
Problem detail: "CREATE DOMAIN" commands intermittently failed.
Log follows:
MCC> create domain .imperial
Domain US0V00_NS:.imperial
AT 16-SEP-1991 18:14:39
The requested operation cannot be completed
MCC Unhandled Service Reply = The requested operation cannot be
completed
MCC Unhandled Service Reply = No such entity: Domain
US0V00_NS:.imperial
Unknown Entity = Domain US0V00_NS:.imperial
DNS> show dir . known objects
Object _____ ADMIN
Object _____ ADMIN_MCC_EXT000
Object _____ DNA_Registrar
Object _____ us0v00_ch
Object _____ us0v08_ch
Object _____ us0v72_ch
MCC> create domain .imperial
Domain US0V00_NS:.imperial
AT 16-SEP-1991 18:16:41
Create Successful
Problem Cause: The MCC TDF (Time Difference factor) did not match the
DNS TDF!
Problem Solution: Had to redefine the TDF Logical!
4 - DNS: Object partially registered
Problem detail: "DIRECTORY NODE4 * " command, after showing 2 entries
failed, with some error like "No such entity".
But in DNS
DNS> show dir .dna_node known objects
showed many object (nodes).
Problem Cause: It turned out that the node was partially registered
Maybe (and hopefully) due to the previous problems.
Problem Solution: Had to delete the object and its links in DNS!
Note: I must state that few days ago (as I was writing this report)
someone in my group encountered very similar problems to #3&4.
Although the symptoms were similar the causes were different!
Recommendations: (in relation to problems 1 to 4)
2 document are badly needed!
First, a MCC-DNS troubleshooting guide needs to be
developed. This was raised in the notes file a long time
ago, and it was stated that there will be a MCC-DNS
troubleshooting guide, but it has not materialized yet.
Such a guide will eliminate a lot frustrations, and will
make MCC a much easier product to use.
Second, a document explaining "how MCC works with DNS",
must be developed. This document should explain
directory structures, domains, objects, synonyms, links,
what data is stored where, how data is accessed by
MCC commands, etc, etc. This info will be invaluable for
people with more experience, and will help them plan and
troubleshoot MCC-DNS problems.
5 - Registration: Cabletron Hubs
Problem detail: Customer was not satisfied with the fact that he could not
register Cabletron Hubs as Ethernet Stations.
Problem Explanation: Explained to the customer what can be registered
as Ethernet Station (ie: comply to 802.3, Ethernet
V2). Also talked about their option of buying the
SNMP AM, if the vendor complies to SNMP, etc.
Recommendations: It will be extremely useful if a list of the most
popular vendors products that are currently manageable
w/ethernet_am, and a list of vendor products that will
be manageable w/SNMP AM be made available.
I understand that there are too many products
out there and this sounds impossible. But if someone
just puts a list together of most popular vendor products
(ex: Cabletron hubs, Wellfleet & Cisco routers).
that are known today to be manageable/ not manageable,
it will a great help in setting the customer's
expectations right, from the beginning. (There are
already a lot of notes in the notes file in this
regard...that can be a starting point..).
6 - Registration: Not able to register unreachable entities
Solution: Known restriction. Will be fixed in V1.2
7 - Ethernet-AM problem with DECconcentrators
Problem detail: I have explained the details of this problem in the
MCC notes file # 1500.
Problem Solution: We upgraded to ELM AM - Customer seemed satisfied.
8 - Iconic Map: Drawing lines in iconic map
Problem detail: When connecting 2 objects to each other or when
connecting an object to another line (ie: Line presenting
Ethernet), the Iconic map seemed to have the mind of
its own!!
There seemed to be problems/limitations with X & Y axis!!
ie: when trying to connect object A to Ethernet with a
65 degree angle line, the line would change to a straight
line!!! This can be very annoying when one is building
the map for almost a full day (ie: first time creating
the map of the network) The customer was very annoyed!
9 - Iconic Map: Names are too long. Want to be able to use the synonym
Problem detail: Customer did not like the very long names on the map!
ie: .DOMAIN.BUILD1 , .GLAXO.US.DNA_NODE.VAX001
Wants to be able to use synonyms and not be restricted
to DNS names.
10 - Iconic Map: Not able to display non manageable objects
Issue detail: Even if MCC could not manage the Cabletron Hub the
customer wanted to be able to show it on the map,
so he could have a complete representation of his
network.
11 - FCL: Need to be able to set alias (synonym) for any object (ie:Bridge
and Stations
Example: Instead of:
MCC> SHOW BRIDGE .GLAXO.US.FDDBRIDGE.B1TOB3 ALL COUNTERS
want:
MCC> SHOW BRIDGE B1TOB3 ALL COUNTERS
12 - Alarms: Creating alarms is hard and inconsistent
Problem detail: I tried very hard to make this easier this time around.
I told the customer up front that the best way is to
create alarms with Com.files! Also created several
sample alarms for both Node4 and Bridges and made sure
they work.
However, even with com.files you can run into many
problems. For example, there are two ways to create
alarms which accomplishes the same thing
1) CREATE DOMAIN name RULE x
2) CREATE MCC 0 ALARMS RULE x, IN DOMAIN name
But, the syntax of qualifiers are inconsistent between
the two. ex: "SEVERITY", vs "PERCEIVED SEVERITY", etc.
Recommendations: At least the two should have the same syntax; and
in general we must make use of alarms easier.
13 - Alarms: Need wild card support
Feedback: Like to be able to see more wild card support capabilities,
with alarms. This issue is already discussed in the notes
file, in more detail.
14 - Alarms: Limit for # of alarms ????????????
Problem detail: Every time that this subject has been raised internally,
the response has been "It depends". This does not
work with the customer! We need guidelines.
Recommendations: Engineering must provide guidelines, with "SPD's Minimum
Recommendations" (a 3100 with RZ56, 32 meg) and the
default polling values (ie: every 15 minutes, etc - They
are in the documentation!)
15 - Alarms: Could not create an alarm for "Designated router address"
Problem detail: The customer wanted an alarm for when the designated router
changed. So I tried to create the following rule:
EXPRESSION: (NODE4 name CIR EHTERNET DESIGNATED ROUTER
<> 1.3)
but found out alarms for comparing "address" is not
supported!
16 - Historian: Need wild card support for SHOW RECORDING
Problem detail: Need wild card support for 'entity class', for
'in domain' and for 'partition"' qualifiers,
when "Show Recording". ie: need support for
MCC> SHOW RECORDING NODE4 * PARTITION=*, In DOMAIN *
MCC> SHOW RECORDING NODE4 * PARTITION=COUNTERS, In DOMAIN MKO
(which today gives wrong information - a bug?)
MCC> SHOW RECORDING NODE4 name PARTITION= *, In DOMAIN MKO
Justification: In a big network, with several people managing the
network, it is hard to know who sets up what & when.
Having to issue this command for each entity is
just not acceptable.
17 - Exporter: Case sensitivity of Exporter to the Entity name
Problem detail: A known bug.
18 - Exporter: Need wild card support for SHOW EXPORTING
Problem detail: Need that for 'entity class' and 'Export Target'.
Same reason as 17.
(Note: Note sure if it is the Exporter problem or MIR or somethings
else?)
19 - Exporter: Not able to export the Recorded data from the MIR
Problem detail: Known bug.
20 - Exporter: Want to have an "archive" option in addition to "PURGE"
Issue detail: The customer wanted to be able to ARCHIVE old exported data,
so the data could be backed up to a tape for future use.
This will allow for setting the "KEEP AGE" value very low,
hence saving on disk space but not worrying about loosing
the data.
21 - Reports: No Reports available for Bridge
Problem detail: The customer was not satisfied that no reporting was
available for Bridges. This customer's network is
pretty much a big extended LAN with many bridges (few
routers), which is not uncommon!
I did explain that they could write their own reports,
but the customer is not familiar with Rdb, and does not
believe he should put the extra effort and cost for DEC
Bridge reports.
22 - Time: Syntax is confusing and inconsistent, from FCL
Problem detail: The "TIME" syntax is hard! I don't know how we expect
the customer to remember it all. It is inconstant,
unfriendly, too many rules/ifs & buts; plus errors
in documentation.
23 - Time: Using Time widget in Iconic Map is difficult
Example: After the time is changed so the "Historical statistics"
could be reviewed, it is hard to change it back to "now".
Many times you will not notice that your attempt to
change the time back to "now" did not succeed until
you try an "operation" in present time, (ex: SHOW
STATUS) which will fail!
24 - Error message: confusing and misleading, at best!
Problem detail: The current Error Messages are misleading, confusing,
and not very helpful.
Recommendations: Please improve the error messages. I have
many examples if anyone is interested. I will try
to put them in the notes file.
25 - Efficiency: Run alarms more efficiently
Issue detail: The customer had a concern about Performance and additional
network traffic that alarms create on the network.
The feedback was that they would like to see more efficiency,
for example combining several alarms, so when the entity
is pooled, all the necessary data is gathered in one pool,
rather than polling the same entity several times.
26 - The "Ethernim convert utility" did not create the bridge and stations
com files!
Problem detail: Unfortunately I can not re-created this problem, locally.
The scenario was that I enabled "Ethernim Monitor for
SYS-ID". I could show bridges (ie: with SET NODE address
command). Ethernim knew about over 1000 stations! But the
MCC_LOAD_ETHERNIM_BRIDGE.COM; was empty, with only
the headings! ie:
$
$ type MCC_LOAD_ETHERNIM_BRIDGES.COM;
!
!++++++++++++++++++++++++++++++++++++++++++++++++++
! DECmcc generated this command file on 27-SEP-1991 16:09:04.01
! to load ETHERnim database information into DECmcc
!--------------------------------------------------
!
$
and the MCC_LOAD_ETHERNIM_STATIONS.COM; had only 2
stations!
After a couple of tries, gave up and created a com file
manually to register the bridges. However, I thought it
worths mentioning in case someone else has seen this.
Also was wondering whether there are any error messages,
or log files to help determine what the cause is, if and
when this happens again.
27 - Iconic Map: Could not move a group of entities
Problems detail: After we created a map of the network, the customer
was interested to move the whole map 1/2 inch down,
cause everything was jammed in one corner.
But could not select more than one entity and move them!
Summary:
This was my 3rd DECmcc installation & setup and it still was quite
painful!! I tried to make it as easy as possible for the customer,
but there is only so much that can be done!
I know there has been a lot of good work put into this product,
and I personally believe it has great potentials; but in addition
to bug fixes, we need to make it easier to use and a lot mor user
friendly, before it becomes a popular and competitive product.
Comments from engineering on these issues is appreciated.

1685.1 | | TOOK::STRUTT | Management - the one word oxymoron | Wed Oct 23 1991 19:43 | 301 |
| Mahnaz,
our sincere thanks for:
1) persevering
2) taking the time to document the details for us
This sort of information is very useful to us in development - we are
trying hard to build the best product we can, but you will appreciate
there is a fine line between features/functions and things like sleep :-}
I'd like to address your points one at a time...
1 - DNS: Inflexibility of location of MCC directories
Problem Detail: They had a DNS naming plan/structure, and wanted to
maintain that. (At the root only one directory -
.Glaxo - One directory under that, for each country -
.GLAXO.US, .Glaxo.UK , etc). They wanted me to put
all the MCC directories under the .GLAXO.US But I
had to tell them that the only ones that I could put
there are .DNA_NODE and .MCC directories. The
DNA_NODESYNONYM and the BACKTRANSLATIONs have to be
at the root.
They were not very pleased with that!
I know the customer is always right, but is this something like
expecting the speed of light to be different? How did Glaxo get the
impression that they could use the name space in the way that they
wanted to - ie. that there would ONLY be one directory in the root?
Other things (like ADVANTAGE/NETWORKS - n�e DECnet/OSI) put stuff in
the root directories too.
Is it that we did not explain adequately how MCC uses the name space or
is it a more general problem that we haven't explained how to use
naming services?
2 - DNS: Access control problem
Problem Solution: This is a DNS known problem.
ok
3 - DNS: Registration problem
Problem detail: "CREATE DOMAIN" commands intermittently failed.
Problem Cause: The MCC TDF (Time Difference factor) did not match the
DNS TDF!
Hmm - it's a shame we let you do things wrong, and then return errors
in quite unexpected places.
I've entered a QAR (#1090) with a suggestion that the installation
procedure check the MCC tdf against the DNS tdf (if it can determine
it).
4 - DNS: Object partially registered
Recommendations: (in relation to problems 1 to 4)
2 document are badly needed!
First, a MCC-DNS troubleshooting guide needs to be
developed. This was raised in the notes file a long time
ago, and it was stated that there will be a MCC-DNS
troubleshooting guide, but it has not materialized yet.
Such a guide will eliminate a lot frustrations, and will
make MCC a much easier product to use.
Second, a document explaining "how MCC works with DNS",
must be developed. This document should explain
directory structures, domains, objects, synonyms, links,
what data is stored where, how data is accessed by
MCC commands, etc, etc. This info will be invaluable for
people with more experience, and will help them plan and
troubleshoot MCC-DNS problems.
Both are good suggestions - I'm not sure how much of this will appear
in the MCC v1.2 doc set. Certainly there is more explanatory material
in the v1.2 documentation about how to set up (we refer to it as
deploying) MCC so that you may manage your network.
5 - Registration: Cabletron Hubs
Problem detail: Customer was not satisfied with the fact that he could not
register Cabletron Hubs as Ethernet Stations.
From your description, I am unsure whether you mean that the Cabletron
Hubs are not supporting the 802 XID and TEST messages (and hence would
not be manageable as Ethernet Stations) or whether the Hub *does*
support those messages and there is a problem with the Station AM.
Please could you be a little more specific? Thanks.
6 - Registration: Not able to register unreachable entities
Solution: Known restriction. Will be fixed in V1.2
As you say, fixed in v1.2
7 - Ethernet-AM problem with DECconcentrators
Problem Solution: We upgraded to ELM AM - Customer seemed satisfied.
ok
8 - Iconic Map: Drawing lines in iconic map
Problem detail: When connecting 2 objects to each other or when
connecting an object to another line (ie: Line presenting
Ethernet), the Iconic map seemed to have the mind of
its own!!
There seemed to be problems/limitations with X & Y axis!!
ie: when trying to connect object A to Ethernet with a
65 degree angle line, the line would change to a straight
line!!! This can be very annoying when one is building
the map for almost a full day (ie: first time creating
the map of the network) The customer was very annoyed!
Fixed in v1.2 - there's a bug in v1.1 where the "snap to grid"
algorithm was being overly helpful.
9 - Iconic Map: Names are too long. Want to be able to use the synonym
Problem detail: Customer did not like the very long names on the map!
ie: .DOMAIN.BUILD1 , .GLAXO.US.DNA_NODE.VAX001
Wants to be able to use synonyms and not be restricted
to DNS names.
This is currently on the list of suggested enhancements, and is
unlikely to make it into v1.2
Our thoughts in this area are to allow icons to be named in a way
chosen by the customer (but with sensible defaults out-of-the-box).
Right now you are constrained to displaying the fullname. We'd like to
be able to customise this on a per-class basis, and even override it
on a per-instance basis, to allow the name to display as:
1) full name
2) nothing
3) portion of the full name
a) left most part only
b) right most part only
4) some other identifier (such as IP name, Ethernet address, DECnet
Phase IV node name or address, etc.)
10 - Iconic Map: Not able to display non manageable objects
Issue detail: Even if MCC could not manage the Cabletron Hub the
customer wanted to be able to show it on the map,
so he could have a complete representation of his
network.
You will be able to do this in v1.2
11 - FCL: Need to be able to set alias (synonym) for any object (ie:Bridge
and Stations
You do have some capabilities already, with DNS and MCC.
For example, with DNS you can assign a synonym.
With MCC, you can use SET DEFAULT ENTITY to establish a default entity
to apply to future commands, such as:
USE DEFAULT ENTITY NODE4 FOO
SHOW ALL COUNTERS (to get NODE4 FOO's counters)
SHOW CIRCUIT * ALL COUNTERS (to get counters for
NODE4 FOO CIRCUIT *)
In addition, we have ideas of providing an additional MCC default
mechanism in a release after v1.2 to allow you to specify the default
namespace directory. This will be useful when dealing with (otherwise
quite long) DNS names. Thus we might implement something like:
USE DEFAULT NAMESPACE DIRECTORY DEC:.lkg.bridges
so that future DNS names will be looked up in the bridges subdirectory.
12 - Alarms: Creating alarms is hard and inconsistent
Yes, you are quite right - this is an area that has received and will
continue to receive much scrutiny. We'd like alarm creation (and all
that entails) to be as simple and straightforward as possible).
Our approach, so you understand it, has been to provide an extremely
powerful general purpose capability. Now our attention needs to be
placed on making it more usable and user-friendly. Expect to see major
improvements in releases after v1.2
13 - Alarms: Need wild card support
Agreed - this is on the list to do after v1.2
14 - Alarms: Limit for # of alarms ????????????
Agreed - we have provided some of this information in the past and we
can always do better.
If you have some specific suggestions for case you would like us to
document, please let us know - no promises, but it will give us a feel
for what is needed by our customers.
15 - Alarms: Could not create an alarm for "Designated router address"
Alas, this is a current restriction and will not be lifted in v1.2.
It's on the list for after v1.2
16 - Historian: Need wild card support for SHOW RECORDING
We clearly understand the need.
Partion=* is supported in v1.2
Child entity wildcarding (NODE4 FOO CIRCUIT *) works since v1.2
Global entity wildcarding (NODE4 *) works by the PM expanding the
wildcarding - hence it does not do "the right thing" for the user.
We know how we'd like to fix this, but it requires platform changes
so won't happen till after v1.2
Also on our list of things for after v1.2, is a LIST RECORDING
directive to show all recordings for a given domain.
17 - Exporter: Case sensitivity of Exporter to the Entity name
Problem detail: A known bug.
Use of a DNS name is, indeed, case sensitive. However, things like
DECnet Phase IV nodenames do work properly, we believe.
18 - Exporter: Need wild card support for SHOW EXPORTING
Same as #16
19 - Exporter: Not able to export the Recorded data from the MIR
Problem detail: Known bug.
Fixed in v1.2
20 - Exporter: Want to have an "archive" option in addition to "PURGE"
This is on the list for future work
21 - Reports: No Reports available for Bridge
Please would you indicate what reports you'd like - and we can see
what we can do.
22 - Time: Syntax is confusing and inconsistent, from FCL
There's no doubt it's confusing - the result of taking what is allowed
internally, and making it available to users, without the benefit of
translating the capabilities into something usable. We do need a
simpler way for the user to specify time - even I get confused!!!
23 - Time: Using Time widget in Iconic Map is difficult
As in 22, the IMPM needs some attention too - there have been some
improvements in v1.2, but we probably need to do some more work here.
24 - Error message: confusing and misleading, at best!
Please provide your info to Steve Jong (WORDY::JONG)
25 - Efficiency: Run alarms more efficiently
Frankly I don't know how to respond to this - anyone else?
26 - The "Ethernim convert utility" did not create the bridge and stations
com files!
I don't know why this happened - anyone else?
27 - Iconic Map: Could not move a group of entities
This is on the list of future work for after v1.2
Summary:
This was my 3rd DECmcc installation & setup and it still was quite
painful!!
We apologise - but thank you for persevering!
I tried to make it as easy as possible for the customer,
but there is only so much that can be done!
Agreed.
I know there has been a lot of good work put into this product,
and I personally believe it has great potentials; but in addition
to bug fixes, we need to make it easier to use and a lot mor user
friendly, before it becomes a popular and competitive product.
Well, usability has been a major concern with v1.2 (along with adding
"necessary" features). There is a delicate balance between new features
and usability. We are continuing to work hard in this area and
appreciate your support and patience - especially as you have to
represent us to our customers.
Thank You!

1685.2 | Comments from other customers | VIDOAN::DOAN | EIS/Network Consulting Group of the 90's | Thu Oct 24 1991 16:28 | 43 |
| Hi,
My name is Thien Doan working as network consultant in the same group
with Mahnaz Mehr. Since she has brought out the comments from her
customers, i will do my part to express customers comments that I have
received in the past few months. My customers are the many large account
that we have such as,
AECL, Canada
Hershey Chocolate, PA
Lee County Gov't, FL
GE, NY
CORNING, NC
...... and a few more.
The list of my customers comments pretty much identical to the one
that was provided in 0., plus a few more. In general, DECmcc is NOT
as user-friendly ( or network manager-friendly) as the customer has
expected. Yes, it's a complex system but it should allow the users
to set it up and using it with minimal frustrations.
Out of many, the most common problem is the setting of the namespace
for MCC use.This is should be clearly written in a detailed document
with samples of case-study to minimize the confusions and pains.
I have posted several notes regarding this topic, please let me know if
we can provide any help in putting this document together since we have
some experience/recommendations from the real-world network managers.
I also strongly agreed to Mahnaz in the following issues:
1,2,3,5,6,9,12,16,17,18, and 19.
I will be adding comments from customers as we continue to provide
DECmcc-consultancies to our customers.

| Re .1:
Colin,
In return I like to thank you for taking the time and responding
to every issue. For people like me out in the field it means
a lot to know that someone really cares to listen to our feedbacks;
it makes thing that much easier...
>> This sort of information is very useful to us in development - we are
>> trying hard to build the best product we can, but you will appreciate
>> there is a fine line between features/functions and things like sleep :-}
I know. Since I have been working with DECmcc, I have got to know
some of the engineers over there and I know how hard everyone
works.....We all appreciate it!
I have some clarifications and follow ups on few of the issues.
RE: issue #1:
>> Is it that we did not explain adequately how MCC uses the name space
>> or is it a more general problem that we haven't explained how to use
>> 2 naming services?
Frankly both. But perhaps mostly the first one! There is no document
that explains how MCC uses DNS. Is there? Answering questions like:
What directories are used by what modules? where the directories
can/must reside in DNS? what are the backtranslation directories
used for exactly? why the .MCC_Bridge_BackTranslation and
.DNA_BackTranslation &.....have to be at the root, is it MCC
restriction or OSI or DNS? (neither I or customer are or should
be OSI or DNS *experts* to use MCC!) What if the customer buys 2
or more DECmcc, (2 DNS servers, 2 clearinghouses and one namespace)?
-which is similar to Easynet's case- What are do's and don'ts then?etc.
If there is such a document, please give me the pointer to it.
Further, we (Digital) emphasis on "NameSpace planning". So the
customer goes and plans its namespace. But then we tell them, No! you
actually can not do it that way, cause MCC doesn't let you!!
Other products such as RSM and DFS don't have any DNS directory
location restrictions; and that is what Glaxo has been using DNS for.
So to customer it is a MCC problem!
Now, I understand that it is possible that this could be a Phase V
restriction (is it?) and if it is, we might hear complains about
that too!!
RE: issue #5. Cabletron Hubs
Let's put it this way; the customer was under impression that
he will be able to register his Cabletron hubs and do some "show"
and "test". And when it didn't work he was disappointed. That is all.
Frankly I do not know much about Cabletron Hubs. But I do not
assume there is anything wrong with Ethernet AM. Sorry if I implied
that. I was just wondering if there is a list available as to
what devices can and can not be managed/registered by Ethernet_AM.
So the customer's expectation is set properly from the beginning.
May be this is not a MCC engineering issue; but a field person like
myself wouldn't know what works or doesn't work either until I
go to customer site (we certainly don't have these devices in house)
and the customer has been sold on the "Multivendor managability"!
Now, since I wrote the report, in Ethernet AM documentation, under
the chapter titled:
"Attribute Descriptions"... "This chapter describes the attributes
for the station entity." !
I found a table with the title "Ethernet Device implementation Types".
Could you expand on what that is? Is this the list of all,
devices that work with Ethernet_AM? or...?
In any case, now that SNMP AM V1.1 is available this issue might
not be as important, cause many of the private MIBs are included
(I have that list) with SNMP AM and others can be developed.
....you asked for more clarification.... :-)
RE: issue #9: Names are too long on IMPM. Want to be able to use the synonym
Assuming that all these issues will get priority points as they
are raised by more and more customers, I like to say this is one
of the issues that has been brought up by every customer. They
really don't like it!
RE: issue #11: Need to be able to set alias (synonym) for any object
What you suggested, is helpful if one would want to do several
commands on the same entity. But if one is going to look at
different entities another mechanism, such as what is planed for
future releases is required. It would have been nice to have it
at V1.2.
RE: issue #14: Limit for # of alarms ????????
>> Agreed - we have provided some of this information in the past and we
>> can always do better.
Is this info documented somewhere? could you give me the pointer?
>> If you have some specific suggestions for case you would like us to
>> document, please let us know - no promises, but it will give us a feel
>> for what is needed by our customers.
The limit for the # of alarms that can be handled by a system
such as what is recommended in the SPD:
A 3100, with RZ55, with 32 meg of memory;
Plus default alarms polling values:
Poll every 15 minutes...
This then need to be expanded considering Historian and Exporter
polling.............
Overall we need much performance and sizing information. It would
be very helpful if DSTEG and/or NPACE performed some tests in
this area, and make the results available to everyone.
RE: issue #17: Case sensitivity of Exporter to the Entity name
>> Use of a DNS name is, indeed, case sensitive. However, things like
>> DECnet Phase IV nodenames do work properly, we believe.
In case of exporter, I could bet that I saw the problem caused
with Ph IV nodename! This customer doesn't even have Wave 1 (if that
is what you mean?) I'll try to look into it again!
RE: issue #21: Reports: No Reports available for Bridge
I did not nail down the customer on this, but what I could
think of top of my head that would be useful:
- Line Utilization Reports
- Report including Bridge Filtering data
- Error reports
Any one else?
RE: issue #22: FCL Time Syntax is confusing and inconsistent
Don't mean to be pushy!! :-) But would there be improvement in V1.2?
Would the documentation be corrected?
RE: issue #26:
I can't expect much on this one since even I can not recreate the
problem;....except some error message would have been helpful.
By the way, thanks to all of you for all the fixes in 1.2
(issues #6, 8, 10, 16, and 19. Plus others not discussed here).
And the rest, hopefully soon :-) ... when? :-) just kidding!
I will continue to provide the customer feedbacks, as we all agree
they are the most important, and I am sure it will help in
prioritizing the issue resolutions.
Thanks again,
Mahnaz

Any device that responds to a REQUEST-ID (MOP V3 or MOP V4) will return,
along with assorted other things, a field indicating what type of device
is responding (e.g. "Vitalink TransLAN 350 NPC25 Bridge").
The possible (enumerated) values of this field are listed in the
table mentioned above.

| Let me respond to some of your points in .3
RE: issue #1:
On explaining DNS name spaces to MCC customers - we had planned to work
on that during v1.2, but for some reason it never happened. Partly as
a result of your input, I asked again for this information to be put
into the documentation. I'm pleased to report that a tech writer is
working on this right now - so we should expect information to be
included in the final v1.2 doc set, thus benefitting all customers.
RE: issue #9: Names are too long on IMPM. Want to be able to use the synonym
We hear you.
RE: issue #11: Need to be able to set alias (synonym) for any object
Clearly it would (have) be(en) nice in v1.2.
RE: issue #17: Case sensitivity of Exporter to the Entity name
Any additional information you can provide to help us diagnose the
problem would be helpful.
RE: issue #22: FCL Time Syntax is confusing and inconsistent
At this stage of v1.2 development, it seems highly unlikely that we
will have the time to define and implement changes to the time syntax
in either the FCL or IMPM. Also, there are probably other areas (such
as ease in setting up alarm conditions or getting better names on the
icons) that are of higher priority and used by more people.
Hopefully other people will provide answers to other points (as Chris
did for issue #5 in reply .4)
Thanks for the continuing dialogue.

I fully agree with the recommendation based upon the min
configuration. The DSTEG group is doing performance and
capacitiy characterizations and measurements. The goal is to
be able to have customers or firld people fill out a simple
"profile" of their networking needs (ie number of objects,
frequency of polls, number of events, etc.) and have a simple
table or other process to determine the hardware platform
needed.
Stay tuned, we're listening and working on it.

1685.7 | Lack of Routing spooks again... | BEAGLE::WLODEK | Network pathologist. | Thu Dec 05 1991 05:59 | 16 |
|
Issue 15, designated router changes.
This is one of many side effects of not having a model of Routing
layer. DECmcc really needs that as a separate module ( FM ? ).
The "retargeting" in V1.2 is really a terrible kludge to go around that
problem ( person setting up MCC "models" Routing, computers should do
it).
There are many other routing problems that one cannot alarm on just
because we don't model routing.

Wlodek
