How to configure NUT for Tripp Lite UPS using SNMP

azdeltawye

Hello,
As the thread title suggests, I am trying to figure out how to use snmp on my Tripp Lite SMART1500RMXLN. I was successfully using the USB connection but it stopped working since upgrading to 23.01 and I don't feel up to editing system files or whatever tweaking is needed to get the USB connection working again. I figure since the UPS has a network card, it should be simple enough to get the snmp working.. Right?

Here are some screenshots of my setup.
Any help would be appreciated.

Extra Arguments to driver:
secName=test
authPassword=xxxxxxxxxx
privPassword=xxxxxxxxxxx
privProtocol=AES
authProtocol=SHA
snmp_timeout=5
secLevel=authPriv
snmp_version=v3
desc="SNMP v3"

pfSense error logs:

Not necessarily.

First, I would recommend that you begin with snmp v1/v2c using a read-only group. The battery level of your UPS is not really a secret that needs encrypting.

Second, I would test with snmpwalk from a unix machine, and confirm that you are able to do that before attempting anything with NUT. Trying to debug basic SNMP issues via NUT is guaranteed to be a frustrating experience.

Thanks for the response!

This sounds like it is way above my knowledge level. I've never heard of snmpwalk. Is that something I could run on a raspberry Pi?

In all honesty, I was hoping for some kind of cookbook procedure from someone who had successfully set this up...

I'll probably just have to wait for the Local USB fix, hopefully in the next version of NUT...

Thanks again for the help.

Yes, I would expect that you can run it on a Pi assuming you have SNMP installed. Example:

snmpwalk -v 1 -c public 192.168.1.1

Where 'public' is the name of the SNMP community, and '192.168.1.1' is the IP address of the UPS.

As to the local USB situation, there is an easy workaround discussed here, or an updated binary available here.
