SNMP on Sophos Switches, why so complicated?

I'm trying to configure SNMP on Sophos Switches and I can't seem to get it working.  Looking at the options and documentation it's pretty cryptic. SNMP - Sophos Switch documentation

All I need is to set a community string, SNMP version and make it read only which is very easy to do on all switches except this one.  Anyone go through the process and figured it out?
