Creating a visual Map of a network?
Neil Jones
find the systems on the local LAN and remote LANs (same enterprise).
This time I want to create a visual map of the LAN. With cheops, I
reasonably good results but cannot be documented for managers with
certainty. What are some good tools now that will create visual maps of
the networks?
What is the best way to map a network when ICMP echo has been turned off?
Thank you in advance for any help.

Visio and CDP. I know Visio used to have a network discovery module,
but I don't think its around anymore. To be honest, every time I have
used a shortcut app to do this, I still end up re-doing it in Visio to
make it adequate for presentation/distribution but also still be very
usable. Just my 2 cents.

I have tried some network visualization tools with some fancy auto
detection features and ended up drawing the maps by hand.
I have used several tools for this staring from visio and dia, but
finally I ended up using Graphviz.
Using some simple makefiles I can assemble a customized .dot file from
different locations including more or less informations - and it is easy
to keep it under CVS, because its only text. And you can add some nodes
using vi over a slow connection.
As far as I remember there are some scripts around that generate a .dot
file from the nmap output.
Maybe you should give it a try ;-)
It may take some time to start up, but it may be worth investigating
some effort.

Every time I troubleshoot, I used to draw a Visio map. it had L3/L2
info, port errors, CEF Exact path etc. Finally, I got sick of doing
this and asked one of my guys (who used to be programmer) and asked him
to watch what I did. Then I asked him if he could programatically do
this. He wrote a Visio (VB) script that did it! It only does source
to destination (not the whole site), but we -only half - jokingly call
it "The Tool" As in "it's The Tool you need to troubleshoot"
Email me if anyone is interested. It's fairly easy to find my address
(with my name) via google. My older posts even had ROT13 addresses in
them. :)

http://safemap.sourceforge.net/ - it's even written by Cisco :-)

ARP, perhaps? Traceroute and CDP might help also. I believe some [all?]
switches report what MAC has been seen on each port via SNMP. Netdisco
[netdisco.org] might also be interesting to you. If you're running a
routing protocol, some of the 'show' commands might be useful. If you
need to gather the output of a show command on a regular basis, RANCID
would be a good place to start.
