SNMP timeout

Hello all,

I was a given a task to set up SNMP on Zabbix.

When I try to configure the hosts in Zabbix, I get a "timeout while connecting to x.x.x.x". The SNMP community name is configured in Zabbix, under "MACROS" tab. The same community name is configured in the switch. Here is an output from the SNMP configuration in one of our switches.

So the "XYZ" ( random community-name in this case) is the same on both Zabbix and the switch. Logging host is of course enabled. The port 161 is enabled in Zabbix, the switch is in the right group and the correct template is also there.

Here is the configuration from the switch.

We have other switches in the network and SNMP works perfectly fine for them. I compared the setup in Zabbix and the configuration in the switches with those that SNMP is functioning and did exactly the same setup (just different community name) but I still cant make it work, still get "timeout while connecting"

​

Any tips?
