Troubles adding Cisco switches using SNMPv3

[nparrott]

We are experiencing issues when trying to add any of our Cisco switches using SNMPv3. I can add them when using SNMP v1 and v2 but not 3. It shows no ports, or any information except the IP address when using SNMPv3. Below is the error message we receive.

No ports were detected on the switch. Possible reasons for this include:
The switch is currently down
The switch does not exist at the address you specified
SNMP support on the switch is disabled

Any help would be appreciated.

Thanks!

I suspect SNMPv3 is not enabled on the Cisco device, but I'd need to know the device type to give specific instructions. I did find http://docwiki.cisco.com/wiki/Snmp_v3_configurations

What happens if you do an SNMPv3 walk from the commandline on the Nagios server?

The command will look something like snmpwalk -v3 -l authPriv -u snmpadmin -a MD5 -A PaSSword -x DES -X PRIvPassWord 127.0.0.1:161 system, but obviously change for your environment.

good morning, thanks for the reply. I actually got this working late yesterday afternoon. It turns out I had created a group, had everything done except I forgot to associate a view with the group. Once I did that things took off! I appreciate your time.

I'm assuming this is a Nagios XI group, and a Nagios XI view? I feel pretty confident that's a yes, but would be great to get clarity for anyone that finds this post in the future, since we don't have Cisco switches on which to test. Thanks!

Correct.
