Yes it is. I disabled snmp on both controllers and i re-enabled and still the same output.

[rhassing]

Is the communitystring correct?

[orani]

yes it is :/

Both of snmpwalk gives me timeout: no response from 192.168.110.1

Can you run nmap 192.168.110.1 and post the full output? If SNMP walk isn't working then the plugin surely won't either.

This is probably the culprit, since it's showing filtered and not open -

Code: Select all

161/tcp  filtered snmp

Is there a firewall on the AP, or between the Nagios machine and the AP?

[orani]

yes there is a firewall but it has no access list preventing snmp/161 or 162 pass throwgh it!

I have also an HP IMC platform for monitoring an there snmp works fine so i dont think that the firewall causes that problem.

But i will try to bypass it to see if it works...

i will keep you informed.

Try this, it needs to be UDP for SNMP:

Code: Select all

nmap -sU -p161 192.168.110.1

[orani]

Code: Select all

# nmap -sU -p161 192.168.110.1

Because the output says "filtered" it means there is something blocking the port, a firewall or router between the XI server and the device. Here's the output when I run the nmap command:
