[Nagiosplug-devel] Nagios to poll Cisco switch via SNMP v3?

[Honia A]

Hi all,

I have a Cisco 2960 which is configured for SNMP. The machine's IP is 10.10.10.3 and can communicate with the Cisco 2960 switch 10.10.10.2 via SNMP.
(I tested it with snmpwalk -v 3 -u tom -l authPriv -a sha -A [passwordpassword] -x aes -X passwordpassword 10.10.10.2)

And I also modified Nagios's switch.cfg (code below). Nagios is now monitoring the switch. 

I tried running this command ./check_snmp -H 10.10.10.2 -o "ifOperStatus.1" -U tom -A [passwordpassword] -X passwordpassword -L authPriv -P 3 -a MD5 -c 1050

But looks like it's not working: 

SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 3 [authpriv] 10.10.10.2:161  ifOperStatus.1

What I would like to do is configure Nagios to poll this switch via SNMP v3. So I understand the check_command part should be changed but am not sure how to do that. 


Can you please help?

Thanks in advance,
t
