Can't get SNMP to work

I am having difficulty getting SNMP to work, I'm wanting to poll the signal strength and BER on a unit but I cannot get it to work.  I've successfully connected to 820's before obviously this unit is operating a significantly different OS.

I have the SNMP on the Security tab set to v2c only which is what we use and my Community name matches and I believe I have the correct MIB's, but so far nothing is returning any data.

You ever figure this out?  If not, I can help with some troubleshooting.
