Discovery / Re: Discover of ipv6 nodes not working
« Last post by galileo5 on April 28, 2017, 07:18:06 AM »
I get the IPv4 entries with "sh ip arp vrf all". The IPv6 entries are shown via "show ipv6 neighbors " command.

Hi, Rickli!! Thanks for the help!!

So I output my nedi.pl verbosity to a txt file and looked through it. It gets through my seedlist until it gets about mid-way to one of my switches. When it starts to enter the ARP table, it stops. Then the below error appears on the output.

*********************************************************************************
DBD::mysql::db do failed: Data too long for column 'aname' at row 1 at ./inc/libdb.pm line 1921         *
*********************************************************************************

Is there a node name with a total FQDN name that's too long for the field? If so, does anyone have an idea as to how I can expand that field size? I'm not too familiar with MYSQL syntax.

CLI is used primarily for firewalls which don't support ARP via SNMP (for some strange reason). It's also used for Nexus to get all ARP entries from VRFs. Do you not get any entries with "sh ip arp vrf all"?

As a paying customer you can ask me directly, but it's great to see you got help already!

That "stop" thing is from the startnedi.sh script I presume? As ntmark suggested, try running nedi.pl directly and maybe add -v to see all the gory details...

hmm I'm not sure what a "stop" means.
Maybe someone else can answer that.

What happens if you run it from command line manually? does it do the same thing?

the log in /var/log/nedi/nedi.log displays that NeDi only scanned eight of my 200-plus switches, and the last one has "stop".

Here's the tail of the log from today's time stamp (minus IP information):

**********************************************************************************

**********************************************************************************

It's like it only selectively scans certain switches, then stops. It's the weirdest thing. And sure enough, in my Devices > Status view, all eight of those switches are the only ones that don't show outdated discoveries.


Here's my cron:
**************************************************************************
# or 5 min interval (for very small networks)

I'm assuming the cron jobs pipe the nedi output to a log file.
What do the nedi logs say is wrong?

*/30 1-23 * * * root /nedi/nedi.pl -Smvjedw -A"device regexp '^[a-f]'" > /nedi/log/nedi-a-f.log 2>&1

cat /nedi/log/nedi-a-f.log

Discovery / Re: Discover of ipv6 nodes not working
« Last post by galileo5 on April 26, 2017, 02:03:46 PM »
Hallo,

after I installed 1.5.225 ipv6 was still not working so I took a deep dive into the code. From what I can see in the libcli.pm there is only one command used for arp (sh ip arp vrf all) and that shows only the ipv4 addresses and not the neighbour discovery cache for ipv6. So I am asking myself where the implementation of nd is in arpnd CLI.

In libmisc.pm I found, that it is checked wether cli access is available or not. Only if not, it uses arpnd SNMP. Is there a reason to prefer CLI? I commented arpnd cli out and instead started arpnd snmp. Now it seams to work for me on my nexus device.

Greetings
