Marshall,
Layer-2 map is something we want to build. Of course its hard to do
this reliably.

I wrote something like this in Perl a few years back and it's
really helpful, for switches and routers if Zenoss could poll the
devices, get their forwarding database (mac addys and ports) and
their arp tables. Then allow one to see what devices are attached
to a particular port on a network device.
It was tricky with some layer 2 only devices in that you would have
to look at the macs in their table and try and match it up to arp
that may exist in another layer 3 device's table.
The last thing I did with it was to get not only the ip address and
the resolved hostname of a host attached to a piece of network
equipment but tie into LDAP to get additional info about that host
(ie who it belongs too).
Basicly it allowed me to click on a port and see everything
attached to it down to the user info and also the ability to search
on a user, host or an ip address and to find it's port on whichever
network device it resides. As an added bonus to it, I was able to
keep track of static IP address allocation from the polled arps also.
I doubt tieing into LDAP would be something that could be feaseable
in Zenoss since everyone uses different schemes, other than that
part I'd love to see some of the above functionality in Zenoss.
