Hello, I'm using nav in a "simple" lab environment.

On the devices, I have not that (see end of messages). I suspect a mis interpretation of snmp get on the 4948 but cannot be sure :/ I've put everything in a file in case it's hard to see on the mail. How can we proceed to have the correct information? Thanks in advance, Sylvain
Hi Sylvain,
apologies for the terribly late answer. Your posting came around just as we were preparing for our typically long Norwegian summer vacation, and it got kind of buried after that.
First piece of advice is to check `ipdevpoll.log` for messages from the `topo` job about the mentioned devices (also to ensure that all jobs seem to be running correctly, and in a timely manner, on them).
Secondly, I would check to see the actual contents of the SNMP tables on various devices. There are instances where neighbors may be misidentified by NAV, but it helps to see the original data when trying to decipher what is going on.
If you have the IEEE LLDP-MIB definition installed, you can use the snmptable command line to check the full contents in a mostly readable format:
snmptable -Ci -v2c -c <community> <ip-address> LLDP-MIB::lldpRemTable
If not, a simple snmpwalk may do:
snmpwalk -v2c -c <community> <ip-address> .1.0.8802.1.1.2.1.4.1
