Thanks for trying but that just makes it try more things before failing.

Yes, if they were not throw away passwords in a test environment I would
have snipped them out.

In all my testing I discovered the APC AP9630 is kind of flakey when
it comes to SNMP v3.
I have 
   snmpget -Cf -v 3 -u tfsnmpprof1 -l authPriv \
   -a MD5 -A ralow6moHet7zoboP8 \
   -x AES -X tuseL8Pakaz9degim7 \
   tfapc01 .1.3.6.1.4.1.318.1.1.1.1.1.1.0
work one day and the next day fail.

So I will revisit SNMP v3 when I get my hands on a non APC ups that
supports SNMP v3.

Thanks for all your help.

A note for the archives: To get snmpget working I had to rename the
v3 profile I had set up on the APC and create a new one with all the same
info. Then it worked.
When it stopped working (when I came back to it days later) , I renamed
that one and set up a third one again with all the same info. Once again
it started working.  Strange.
