2177.0. "Cisco's attitude...." by FOUR62::LICAUSE (Al Licause (338-5661)) Thu Jan 23 1992 12:26

I recently discussed the Cicso MIB problem with my customer and received some
interesting feedback.

When they went to Cisco to ask why the MIB we obtained did not work and that
we required concise MIB formats, Cisco replied with "what is concise format?"

Thanks much to the person that pointed me to the RFC1212....see earlier note.

When the customer confronted them with this information,  Cisco became quite
defensive and suggested that they buy Cisco's own proprietary manager.
Cisco appears not to have its act together with regard to customer needs.

By the way, I have seen an HP OpenView workstation manage Cisco routers 
using SNMP.  Apparently HP doesn't require the concise format.


Which leads to a question....why don't we allow or tolerate "sloppy MIB format"?

I can certainly understand the reasons for following the suggested RFC and
other proposed or accepted standards, but the customer only sees results
and if another solution can solve their problem, then even the best architecture
or well planned/built product will not be accepted if it does not do what 
they need it to.

Would it be a difficult thing for us to accept a non-RFC1212 compliant
MIB definition? 

It would certainly go a long....long way toward selling MCC and displacing
HP or anyone else if we can manage such entities!!


By the way.....after getting  a pretty through demo of OpenView and
comparing it to T1.2.4, I don't really see that they have that much more
to offer.  In fact, in some cases....(the T1.2.4 graphing function for one),
I believe we do a better job!!!!

One man and one customers opinion....for what it's worth.

2177.1not all cisco has the same attitudeENUF::GASSMANThu Jan 23 1992 12:5619
    HP has an editor that allows editing a mib into the system by hand. 
    Perhaps this is how you saw the cisco mib put in there.  Also, before
    MSU had their compiler, they had a routine that took sloppy mib format
    (for lack of a better name) and shoved it directly into their SQL
    database - things that didn't work were edited using their MIB editor. 
    MCC requires the conversion of MIB to MSL - which requires a bit more
    formal syntax.  The industry is going CSF - so I don't see it as a
    problem that MCC requires it.
    
    Cisco is not still as bad as you say.  They are now aware of what they
    have to do with their MIB.  They are also not always pushing their own
    network manager.  They have it when they need it, but it's not critical
    to their strategy.  In fact, when they win a router bid in a DEC shop,
    they really hate to have to say that the customer requires a SUN
    workstation to run their netmgt software.  They met with Digital a few
    months ago (both MSU and MCC) and either have, or will soon have, a MSU
    station running in their Waltham sales office.

2177.2MSU isn't MCC....FOUR62::LICAUSEAl Licause (338-5661)Fri Jan 24 1992 08:2312
We may have different perceptions internally, but when the cusotmer develops
bad vibs from a vendor, that can mean lost sales.

Can you tell us what they had to say about or with regard to MCC?

Running MSU in their shop is fine, but MCC is really the strategic direction
for DEC, I would assume.  Since Cisco is the predominant router vendor today,
we must be able to manage them from MCC.  My customer has more than 60 units
and is still buying.  This will more than likely be their router of choice for
the next three years.

2177.3Why we cannot handle "sloppy" mibs while other people can.....YAHEY::BOSEFri Jan 24 1992 14:2651

>>MIB definition? 

	The SNMP AM tries to algorithmically map the SNMP mib objects into
	EMA entities and creates an entity model for each mib extension. For 
	this to happen the mib must be clearly defined without any ambiguity. 
	The problem we most commonly face is during the mapping of tabular 
	objects. MIB tables map into child entities. Table index map into 
	the instance identifier for that child entity. 

	To do such a mapping we need to know unambiguosly which are the table
	objects and what they are indexed by. RFC 1212 "suggests" the use
	of the INDEX clause in tabular object definitions, which allow us 
	to correctly create our entity model. In the "old" mib format the
	index clause is not present, and hence we cannot handle those mibs
	properly. 

	The "powerful" GETNEXT snmp request allows us to request
	and receive table objects from the agent, without even knowing what
	the instance values are. However, there is no way we can display this
	information in MCC without having a corresponding entity model in 
	place. This might explain why both MSU and OpenView can handle those
	"sloppy" mibs and we cannot.

	Adding the INDEX clauses to a non-concise mib and making it usable 
	by the SNMP AM is not that complicated once you have all the required
	information at hand. Mike Reilly has already done it for Cisco's mib 
	and he has made it publicly available. Some of our customers have 
	already used it to manage cisco routers. 

	Hope this helps,

2177.4MCC is more than cisco needsENUF::GASSMANTue Jan 28 1992 08:0118
    cisco was shown both MSU and MCC - and they feel they can better sell
    MSU to their customers.  MSU is a SNMP manager by all definitions,
    while MCC is an enterprise manager that also does SNMP.  Memory usage,
    performance, cost, and availability of SNMP related features are some
    problems that MCC must fix before going head to head with simple SNMP
    managers.  Also, remember, while MCC/ULTRIX seems like it's been around
    forever, out in the world cisco sees - MCC only runs on VMS.  I think
    as MCC becomes all it's intended to be, we'll see that classic network
    managers will gravitate to SNMP manager, and classic system managers
    will gravitate to MCC.  MCC's nitch will be the managers that must deal
    in both worlds.  OSI layer 4 is probably the point of distinction.
    The SNMP market will generate over 2 billion dollars in sales over the
    next 5-6 years - so it makes sense for MCC to scale down, speed up,
    become easier to use, and add more end-user features.  Look to MSU for
    the features required to compete in the SNMP market - but focus on the
    enterprise stuff that MCC was designed for.
