They disappear, but it seems if I run a mac suck, they re-appear.

Hi Gerhard
Many thanks for this! It is now in version 2.036005 of Netdisco, just
released to CPAN.
regards,
oliver.

Hi Oliver,
I edited the the 2.035006 source ASA.pm to get the IPv6 neighbors
subsequent to the IPv4 ARP cache and it works fine.
Because of my insufficient perl knowledge I'm not sure that the added
code is perfect. So I'd appreciate if some checks it and do all
further steps for the community.
diff ASA.pm.org ASA.pm
94a95,112
# start ipv6
$expect->send("show ipv6 neighbor\n");
($pos, $error, $match, $before, $after) = $expect->expect(60, -re,
$prompt);
@lines = split(m/\n/, $before);
# IPv6 age MAC state ifname
$linereg = qr/([0-9a-fA-F\:]+)\s+[0-9]+\s
([0-9a-fA-F]{4}\.[0-9a-fA-F]{4}\.[0-9a-fA-F]{4})/x;
foreach my $line (@lines) {
if ($line =~ $linereg) {
my ($ip, $mac) = ($1, $2);
push @arpentries, { mac => $mac, ip => $ip };
}
}
# end ipv6
regards,
Gerhard

Nachricht <59369FAB.756 : 85 : 22358>:
If someone wants to grab the source and edit this file:
https://github.com/netdisco/netdisco/blob/2.035006/lib/App/Netdisco/SSHColle
ctor/Platform/ASA.pm
It could be patched and tested, to issue the v6 command (and cope if
the
command is missing).
Pull requests and/or commit bits are welcome to all :-)
p.s. I suggest working from the latest stable tag '2.035006'.
regards,
oliver.

Hi all,
I am using Nedisco2 and netdisco-sshcollector to get the IPv4 ARP
cache from an ASA5585X device.
Now I want to get IPv6 neighbors from the same device. I read the
documentation in
https://metacpan.org/pod/distribution/App-Netdisco/bin/netdisco-sshcollector
[1] to add a new device class executing the IOS command "show ipv6
neighbors" on the device. But because of my insufficient perl
knowledge I am not able to do that.
Can anyone show me more detailed what to do or have implemented this
allready?
PS: I extracted this issue from my former one with the subject
"Getting IPv6 neighbors cache form Cisco Cat6500 and ASA5585X"
because
the solution for Cat6500 seems not to be same as for ASA5585X.
Thanks for any help.
Gerhard Rappenecker
