Alex is exactly right, I wish to use the sysname with the IP below the name in
the neighbour list without relying on DNS.
Is it possible to have this with the adjustment ? This way you can see the map
with hostname and IP and see how exactly everything fits together..
Thanks J

Hostnames in "Neighbors" will be very useful, and even more - manageable
tooltips (like Muris wants): Sysname with IP or with DNS name.
For example: I'm as a network admin, manage customer network in datacenter,
that does not have DNS for network devices (I can't change this situation), as
a result, on "Neighbors" I see IPs, but I accustomed to see hostname in device
console. Yes I can remember IP and find device in ND2, but ... it's not handy
I think, If ND2 will have option how to show devices names in topology (by IP,
DNS//etc/hosts, SNMP Sysname) it will be very good.
At other side, without DNS record for devices, when I select
"Inventory->Vendor-Cisco", ND2 show me table and first column has device names
(yes we're reading from left to right side) not IP and there it's OK - user
friendly.
For example, CA Spectrum has options "Model naming order": 1. Sysname, 2. IP
addr, 3. Name service. So we can select, what naming order we need while
network discovery

Well, this is embarrassing... turns out we had made a config error in
a template that had been replicated around our new switches. Fixed
that and Netdisco scheduler is happily discovering everything now.
Phew! Well I am relieved it didn't need a deep dive into Netdisco in the
end. Thanks for letting us know.

oliver.

I would welcome a patch for this, as it has been asked before. I guess
you want some configuration or fallback to cover all the options
(sysname, DNS name, IP, combination?).
Try changing the operation of _get_name(), here:

Many thanks,

address, is there anyway of adding in the hostname above the IP, or

If a hostname can be added on along with the IP, it would be most
useful either above or below the IP.
Also make sure domain_suffix is set in your config.

my Netdisco Setup is working properly except the Mac>IP Lookup. I have
tried everything i could but Netdisco is only showing the Mac of a

correct i have set up a new Linux System (Ubuntu 16.04) and did a
fresh Install of Netdisco with the same result.
The MAC-IP mapping is picked up from the local router or default gateway
(i.e., not the switches). See this page for a little more info:
https://metacpan.org/pod/distribution/App-Netdisco/lib/App/Netdisco/Manual/Troubleshooting.pod
Are you definitely polling the router or gateway for the subnet? If so,
when you look at the device details page, what Device Class and Layers
are shown? It should be a specific model class and also include layer 3.

oliver.
Can anyone Help me?

Hello,
I'm not sure whether this question should be sent to users or devel
list...
I use Netdisco 2 and it collected whole network without any problems.
We use Cisco WLC (reported as cisco/AIR-CT2504-K9,
SNMP::Info::Layer2::Airespace) in network. I found that Access Point
Client Count report is empty all the time even WLC shows connected clients.
I checked it and found that when I run ~/bin/netdisco-do macsuck -d
<WLC_IP> from command line, report is filled correctly. But records
disappears when scheduler runs macsuck for same host. When I run macsuck
with WWW GUI for host, records disappear too. I can put records back
when I run macsuck from CLI again.
I checked netdisco-daemon.log and I see that when macsuck runs for WLC
host, it reports 0 found addresses. But when I run it with netdisco-do
-D from CLI, it reports correct count of found addresses.
I checked snmp communication for both cases and I see that WLC
responds same way with same list of connected clients for both runs.
Therefore it leads me to idea about bug in code, but I'm not sure.
macsuck works for all other hosts in my network therefore I expect
that my installation is OK (no problems with DB access or file system
rights).
Did anyone seen something like this? What else I can check?
Sincerely yours,
Jirka Novak

Hi Jirka,
I never had used the report before, tried it now and do see the same as
you say on our CT5508 WLC models.
CLI works A OK, see them, but go away on a web macsuck.
Cisco's running 8.0.140.0
App::Netdisco 2.034000
DB Schema v40
PostgreSQL 9.2.18
SNMP::Info 3.31
