Yeah, this is not surprising. MikroTik LLDP support is pretty recent
and it's a bit buggy from my experience.

Looks like the SNMP::Info module for Mikrotik (which is used by Netdisco)
doesn't support LLDP. Could be that Mikrotik devices didn't support SNMP
back when this module was written.
Yeah, this is not surprising. MikroTik LLDP support is pretty recent
and it's a bit buggy from my experience.
I actually bought a small Mikrotik two weeks ago (RBM11G), so maybe I
can do some basic testing when I add LLDP support to the
Layer3::Mikrotik device class. Won't have time in the next one or two
weeks though.

I waited 6 years for LLDP support, which finally arrived in 6.38, I think.
There is little LLDP-SNMP, according to the Forum.

Hi Ken

Yes, the switches can see their neighbors. I've provided an
attachment with my discovery inside. Possibly you can tell what's
happening by that.
Many thanks for that and for the log, it's a great help in looking into
this.
While I agree with Jeroen that the log does suggest the neighbors are
being rejected incorrectly, I cannot at first glance of the code see why
this would be (and Jeroen's own issue is something else).
So I have updated Netdisco today to version 2.038004 (on CPAN soon)
which has improved logging when queueing neighbors. If you could upgrade
and run the same command again and send the log output, it would be
appreciated.
Many thanks indeed,
Oliver.
Thanks for the tip regarding the subnet scan. I'll try that next time

Are you running neighbor protocols on the switches such as LLDP? This
is needed by Netdisco. Are the switches able to show their neighbors
at the command line? (show lldp neigh)
Alternatively you could run a discover for 10.119.1.0/24 by entering
that at the Netdisco web homepage.

oliver.
Let's say I have a small site with 30 switches wanted to discover all
30 devices (all within 10.119.1.0/24). Per the directions to discover
one device: netdisco-do -D discover -d 10.119.1.1. After this single
device is complete, it stops.

Hi Peter
Many thanks for this! I have just released 2.038005 to CPAN with the
fix.
Apologies that this took a while to get into upstream. Github commit
bits are freely available if you send me a github username :-).
regards
oliver.

Hello,
I just encountered the same problem as seen here on the mailing list
before, e.g.:
https://sourceforge.net/p/netdisco/mailman/message/35825494/ [1]
netdisco@netdisco:~$ ./bin/netdisco-sshcollector
[19512] 2017-11-01 12:17:19 warn WARNING: no entries received from
<paloalto-fw2.mydomain.com>
[19513] 2017-11-01 12:17:19 warn WARNING: no entries received from
<paloalto-fw1.mydomain.com>
Can't use string ("1") as an ARRAY ref while "strict refs" in use at
./bin/netdisco-sshcollector line 115, <$__ANONIO__> line 3.
netdisco@netdisco:~$
The solution to this case is:
In the file
/home/netdisco/perl5/lib/perl5/App/Netdisco/SSHCollector/Platform/PaloAlto.pm
Add a r to both of the the $expect->send statements.
b4: $expect->send("set cli pager offn");
after: $expect->send("set cli pager offrn");
b4: $expect->send("show arp alln");
after: $expect->send("show arp allrn");
Then I was successful:
[19529] 2017-11-01 12:18:00 info [paloalto-fw1.mydomain.com] arpnip -
retrieved 1175 entries
[19529] 2017-11-01 12:18:08 info [paloalto-fw2.mydomain.com] arpnip -
retrieved 1175 entries
[19529] 2017-11-01 12:18:17 info arpnip - processed 2350 ARP Cache
entries from 2 devices
netdisco@netdisco:~$
could someone please add this to the project?
best regards,
Peter
