SNMP NetInventory returns wrong ports and doesn't report all connected devices #603

Bug reporting acknowledgment

Yes, I read it

Professional support

Yes, I know

Describe the bug

NetInventory Task returns wrong port numbers for connections and doesn't list all connections with Unifi-Switches.

Issues this causes:

netinventory Only shows 2 of the 4 connected devices, and all on port 3, while nothing is actually connected on port. See below.

To reproduce

  1. glpi-netinventory --community [...] --host [...] snmp-walk.walk.txt
  2. see wrong output inventory.xml.txt

Expected behavior

For all connections to be displayed and on the correct ports. Here is a somewhat fixed xml, where I manually entered the connected MAC addresses where they belong. (Port 9 being the upstream port) inventory_fixed.xml.txt The correct port information can be found under SNMP node 1.3.6.1.2.1.17.4.3.1 or 1.3.6.1.2.1.17.7.1.2.2.1 image

Operating system

Linux

GLPI Agent version

1.7, Nightly build (git version in additional context below)

GLPI version

Additional context

The snmp walks are slightly edited. serialnumber has been zeroed and MACs have been anonymized by zeroing the first 5 blocks.

Hi @OnSlbWXt

sorry to take care of your issue so lately, I had a lot of work on windows packaging.

I can't actually go forward as it seems your walk is missing some important datas related to connection support. Can you provide the walk generated using the option from the snmpwalk command you'll find there: https://glpi-agent.readthedocs.io/en/latest/bug-reporting.html#snmpwalk-output Then you can send it to me by email to avoid leaking any confidential datas. My email: gbougard <at> teclib <dot> com

Also if not still done, can you test with latest glpi-agent 1.9 version. Some work has been done on ubiquiti support, but this doesn't concern connections detection.

I have good news and bad news: good news: the issue appears to be resolved with agent version 1.9 bad news: I have no idea why and can't reproduce the issue anymore (I suspect firmware updates)

Thank you for the update.

Firmware update can sometime resolve such kind of problem.
