SEL 3555 not responding to SNMP requests  
Firewalll is allowing SNMP requests, but there is no response from SEL 3555 for that request while running a wireshark  
Any help would be greatly appreciated

Ignition doesn't natively do SNMP. Are you using a 3rd party module?

Did you get it working?  
I'm trying to get an SNMP response from the SEL 2742, and I got `array(java.lang.String, [u'Error: no Response'])` using [GitHub - kiilez/Snmp-Ignition-Module: A module that allows the user to use snmp operations in scripts](https://github.com/kiilez/Snmp-Ignition-Module).

What port does the SEL unit SNMP work on?

You got me thinking. I was testing it in the script console, which runs in the designer scope. Duh. It works fine now. 🤦‍♂️
