Nagios Support Forum

I'm trying to add a cisco switch and am getting some errors. I am able to get snmp data from the switch from my computer and verified that I'm not blocking ports.

Hi @michaewlewis, thanks for reaching out.

There are a couple of things I'd want to check. The first is that your initial command doesn't match the command in the "Created by" comment in the file:
You'll want to figure out which command was actually run - the first one seems to have a messed up 'authpassword' entry, and the second has a privacy protocol with no password.

Second, it's not clear to me what the security level for these credentials are - you may want to verify 1) What authentication protocol you're using, 2) whether you're using a privacy protocol, and 3) if you are using a privacy protocol, you'll want to make sure you're specifying a privacy password.

Let me know if that gets you anywhere, or if you have any further questions or concerns.
-Sebastian

I recopied the command from the troubleshooting tip in the wizard and it looks like the created by command matches this time.
One thing that I noticed is the "public@10.13.200.245:161" referenced is weird. I'm not using public for my snmp community name or user or password. Does that need to change or is that just a default thing that doesn't matter?

If it makes any difference for troubleshooting, it looks like I can do an snmp v1 or v2 successfully.
