We're now fully up-and-running on ND2 and are decommissioning ND1 later today.
:-)
Overall we're very happy with Netdisco2. One minor thing that we're missing,
though, is that in ND1 at the bottom of a list it would provide the total
count, e.g., "Matched 75 nodes." or "21 matches." This was useful as a super
quick way to search, say the first half of a MAC address, discover all of the
Nodes that matched, then scroll to the bottom and get the total count. ND2
doesn't seem to provide this. I think it might simply be because ND2 displays
results on multiple pages by default. I have no idea how difficult it would
be, but would it be possible to add something like this? Or is there already a
way in ND2 to get a quick count of Nodes or Devices that match a particular
search term and we just haven't discovered it yet?
Thank you!

fwiw the rewrite rules we are running in our apache are these:
RewriteEngine On
RewriteCond %{LA-U:REMOTE_USER} (.+)
RewriteRule .* - [E=RU:%{LA-U:REMOTE_USER},NS]
RequestHeader add X-REMOTE_USER %{RU}e
just for completeness.

Super! :)

Thanks for the request - I've patched the code for this, it'll be in
the next release (probably sometime in next couple of days).
"Showing 41 to 50 of 3,337"

Sorry, forgot to add that it works well for most tables but Nodes is a
little squiffy, due to the way that the table is constructed (the
records are grouped per MAC, as you see, and this confuses the code).
Not a lot I can do about that without more poking into the guts, sorry.

oliver.

Hi Jeremy,

We have a L3VPN MPLS cloud that we don't see

our
router at each site and let ND pick up the core and access switches
I've committed a patch now that allows netdisco-do to accept prefixes
(subnets in CIDR format) instead of the device IP/hostname (same -d
parameter). I hope this helps with some scripted discoveries and other
tasks.
The only thing I remember ND1 having that I miss in
ND2 is the nodes not responding in X days report.
We don't have this report, but on the general Node search, "*" is
accepted as a wildcard and I've added a patch to allow exclusion of
Device Ports so the results are a little cleaner.
An automatic way to
remove any nodes not reachable in X days would be a cool feature to
have
as an alternative.
Node removal after X days is already a feature:
https://metacpan.org/pod/App::Netdisco::Manual::Configuration#expire_nodes
You can have this happen automatically by adding "expire" configuration
to the schedule (as below) and/or run the "expire" netdisco-do command:
expire:
when: '20 23 * * *'
(Actually you should enable this config anyway, as it does some other
database housekeeping.)
Hope this helps,
regards,
oliver.

If you look at the MAC table, the phones initially come up on
Vlan10,
then get the voice vlan via CDP and switch to Vlan20, hence why you
see the same MAC on both VLANs.
This is on a 3560X running 15.0(2)SE4 code, we see the same behavior
on our 3560Gs and 4500E's as well, all running some variant of 15.X
code.
Many thanks - I've implemented the change to show Voice VLAN and it
will be in the next Netdisco release.

Hi Nick,
It looks like you're not getting any neighbor protocol information at
all from the phones, in which case there's not a lot we can do, sorry
:-(
Having said that, if you can emit something useful from the handsets, I
have made the identification of phones an WAPs configurable, in a recent
commit (will be in next release).
regards,
oliver.
