Bruno,
This is really a judgement call. Clearly, not all functions from NMCC
are available in BMS. However, since you said your customer has no
specific management requirements at this time, you might want to
consider focusing on just BMS and the LAN tools (LTM, ETHERnim,
RBMS/ELMS, and TSM). By most accounts NMCC is a bear to deal with.
Personally, I've had some pretty good luck with NMCC - and rightfully
so since I've worked with it since initial field test.
BMS V1.1 currently lags behind NMCC's functionality in several areas,
including alarming of WAN lines and performance analysis. However, the
quality of NMCC's "alarming" and "performance analysis" is suspect and
not very flexible. BMS currently offers flexibility, and with V1.2 not
far away (late fall?) it starts to get even more attractive. Most of
NMCC's good functionality will be replaced by BMS in the near future.
By the way, don't be fooled by NMCC's canned reporting capability - the
reports are not very useful/attractive (good idea, but wrong
information) in their current form. I believe canned reports are
planned for BMS V1.1 and they will surely be better than NMCC's.
NMCC has a history of database troubles, its mapping capabilities are
inferior to most of today's network management packages, and offers no
future. I would encourage you to look at the NMCC notesfile for an
idea of some of the chronic problems. If your customer is truly
starting out at ground 0, consider leaving NMCC alone. Our group has
been doing customized DECmcc consultancies on a regular basis for the
last two quarters (US & Canada) and we've faced situations where NMCC
is required and where it is not. The good side of NMCC is that it has
default alarming and thresholds. BMS will be a little more manual in
this area, but the customer is preserving their investment working on
BMS.
The above information does not necessarily answer your specific request
for functional differences, but it might give you some information to
help you decide which way to go. The differences in "documented
functionality" can be misleading in some cases.
