Monitoring new routers

Hello... we just added four new CISCO routers to our infrastructure that I'm attempting to configure for monitoring (rather poorly it seems). I have the check_ping monitoring set up without issues but when I try to add any check_snmp I'm not getting any responses : SNMP problem - No data received from host. I'm fairly new to Nagios so I'm not versed in the syntax well but I tried to reuse the commands for firewalls/switches :
Code: Select all
define service {
use generic-service
host_name Host Name
service_description e0/0 Status
check_command check_snmp!-C public -o ifOperStatus.1 -r 1 -m RFC1213-MIB
}
Is there something obvious I'm missing?
Thanks.

I would start with SNMP v2:
-P 2c
-C public -P 2c -o ifOperStatus.1 -r 1 -m RFC1213-MIB
Let us know if that helps.

Thanks for the reply. I made the suggested modification but received the same result :
"SNMP problem - No data received from host"

If you run the command from CLI at /usr/local/nagios/libexec/ - what is the output?

Response from CLI :
"SNMP problem - No data received from host
CMD : /usr/bin/snmpget -t 1 -r 5 -m RFC1213-MIB -v 2c [authpriv] HOSTIP:161 ifOperStatus.1"

Are you allowing SNMP through your firewall on the Nagios server?

We have it monitoring other devices successfully... so I believe so.

Are you able to SNMP walk the device?
Code: Select all
snmpwalk -v 2c -c public xxx.xxx.xxx.xxx -m all 1.3.6.1.4.1

That command results in :
Timeout : No Response from XXX.XXX.XXX.XXX
