Hi Oliver, I will get those details for you as soon as I get a chance to work
through it.

If you can reliably reproduce the problem with Switch1 and CoreSwitch1,
then please would you email me the output of the following commands:
~netdisco/bin/netdisco-do discover -DI -d Switch1
~netdisco/bin/netdisco-do macsuck -DI -d Switch1
~netdisco/bin/netdisco-do discover -DI -d CoreSwitch1
~netdisco/bin/netdisco-do macsuck -DI -d CoreSwitch1
~netdisco/bin/netdisco-do discover -DI -d Switch1
~netdisco/bin/netdisco-do macsuck -DI -d Switch1
...so that is, the same order you describe below, in steps (1), (2),
(3).
My feeling is that the arpnip/sshcollector side of things is not
relevant to this case. Those two processes update ARP entries, but ARP
data lives in a separate table (node_ip) and does not refer directly to
switch ports. It is the discover and macsuck processes that control
Netdisco's understanding of "uplink" and nodes on ports.
I advise you stop the backend daemon (netdisco-backend) during the test,
so you don't have interference. For info, the code where Netdisco checks
"uplink" status and assigns nodes to ports (or skips them), is roughly
here:
https://github.com/netdisco/netdisco/blob/master/lib/App/Netdisco/Core/Macsuck.pm#L359
You can email me at the CPAN address used on this mail list. If you're
unsure, or want to check anything, join the #netdisco IRC channel on
Freenode.

oliver.

No. I did not get anything about accepting connection.
Attached is the results for the command.
Also, I am attaching a sanitized copy of my config file.

Hi Edward
What happens when you stop the processes and then run:
DBIC_TRACE=1 ~netdisco/bin/localenv plackup bin/netdisco-web-fg
(ignore the Twiggy error!)
Does it say "accepting connections..." ?
regards,
oliver.
