Net inventory with switch does not work when only snmpv3

[waaalex]

Describe the bug

Hello,
When i launch net inventory for my switches it does not work when switches are in snmpV3 only.

For working, i have to disable "snmpv3 only" option and put "public" community in snmpV2 on my switches.
Even if in IP scope i only have SNMP3, glpiinventory needs snmpv2.

Maybe an agent issue
@g-bougard any idea ?

Since agent get no answer from device, this is definitely not a plugin or glpi issue

@waaalex You should open a Q&A discussion here: https://github.com/glpi-project/glpi-agent/discussions

Sorry but there is an issue because i have to have "public" snmpV2 community. Another name does not wxork and with command line

glpi-netinventory.bat --host 10.0.3.3 --credentials version:3,username:snmpV3agent,authprotocol:md5,authpassword:A,privprotocol:aes,privpassword:A --debug

It works.
I m pretty sure that there is an issue on plugin or in inventory.
Can you reopen this case please?

"SNMP communication error: no response from host 10.0.3.5" means an error from device or agent/device communication. it'll be a plugin issue if information are not correctly sent, but there is nothing in your issue that demonstrate this. for now, you habve to find more information.

@waaalex

Can you retry with 1.2.1 version, after this version we have refactoring all SQL queries (maybe its the problem)

[waaalex]

Ok i will try as soon as possible.
Will i have to uninstall plugin and install 1.2.1 or is there a downgrade procedure for plugin?

[stonebuzz]

jsut replace plugin and force install (There have been no database changes between these versions.)

[waaalex]

Same issue with 1.2.1. I do not understand.

[waaalex]

Something new.
a clue here : glpi-project/glpi-agent#477
thanks to @g-bougard

I have deleted two switches, netdiscovery has worked and netinventory is ok for ALL switches.
The issue seems to be netinventory that didn't updated switches on database.

This case can be closed if you want. It works on 1.2.1 and 1.2.3.
