SNMPv3 settings on Zabbix 6.4.6

[vitalev]

Hello everybody,
i have zabbix 6.4.6 installed via apt packets on Ubuntu 22.04.3 LTS, i have a problem with SNMP V3 discovery roules for servers Lenovo with Xclarity Controllers.
I have configured on servers a user with snmp v3 parameter :



After I have run the commands below on zabbix server shell sucessfully:

vito@zabbix:~$ snmpwalk -v 3 -u snmpuser -l authPriv -A xxxxxxxx -a SHA -x AES -X xxxxxxx 172.21.204.18 IF-MIB::ifDescr
IF-MIB::ifDescr.1 = STRING: lo
IF-MIB::ifDescr.2 = STRING: eth1
IF-MIB::ifDescr.3 = STRING: eth0
IF-MIB::ifDescr.4 = STRING: sit0
IF-MIB::ifDescr.5 = STRING: usb0

vito@zabbix:~$ snmpwalk -v 3 -u snmpuser -l authPriv -A xxxxxxxxx -a SHA -x AES -X xxxxxxxx 172.21.204.19 IF-MIB::ifDescr
IF-MIB::ifDescr.1 = STRING: lo
IF-MIB::ifDescr.2 = STRING: eth0
IF-MIB::ifDescr.3 = STRING: eth1
IF-MIB::ifDescr.4 = STRING: sit0
IF-MIB::ifDescr.5 = STRING: usb0


i have setup the host snmp filds in zabbix as folow:





and hosts macros



But i receive this errors from zabbix:

Cannot connect to "172.21.204.19:161": Authentication failure (incorrect password, community or key).

or

Timeout while connecting to "172.21.204.18:161"

I have tryed to chenge authentication and pryvacy protocol but the problem persist

Any idea?

V.

Did you check the SNMP port in XCC Server? by default Lenovo use port 162 instead of port 161.

Check your auth and privacy protocols, are they matching ... SHA1 vs SHA256 etc...

This is just plain bad... 161 is agent port. 162 is trap port...

Hi! where you able to make this work?

Hi! where you able to make this work?

I would suggest you to create a dedicated thread explaining your setup, tests you've done and errors you see.

In original question in this thread the likely reason is wrong Privacy protocol. If I remember correctly the net-snmp package (which includes the snmpwalk command) AES option invokes AES128 under the hood, while on screenshot of topic caster he set it to AES256 in Zabbix UI. But that not necessary mean you hit exactly same issue in your setup
