Good question. I hope someone takes the time to answer. Documentation is one
of the
most important, and most neglected, aspects of the networking profession.
Establishing
a baseline is a good start. It includes not only traffic statistics but also
configurations, cabling, logical and physical topologies, and anything else
that might
make the job of maintaining and troubleshooting a network an enjoyable
challenge
instead of the headache it can be without documentation.

I have a potential customer who refuses to acknowledge the need for
documentation. He's
got an AVVID network that "works just fine without having to hire a
consultant to draw
a bunch of diagrams" as he puts it. The guy who installed it told him it was
zero
maintenance, and nothing I've said thus far can convince him otherwise. So
I'm
preparing a slideshow about network documentation and baselining. I'd
appreciate any
suggestions, horror stories, success stories, etc.

My philosophy is: Plan for failure. I don't mean that in a pessimistic way.
It's just
that, given enough time, all networks fail in one way or another. Some
events are
disasters, others only an inconvenience that can be worked around and coped
with by
non-technical users. But in the long run, something serious will happen,
It's our job
to be prepared for that and to reduce the negative impact as much as
possible.

How do we convince clients to invest in baselining, contingency plans and
the like?
Does anyone have a good book on this? other than the usual ones, like the
CIT cert exam
preps and Semester 8 from the CNAP curriculum? Is there any specific book or
chapter or
website that gives a template for baselining, network documentation,
contingency
planning?
