Thank you for replying.
As noted above, I already upgraded to the latest firmware. That actually made less variables available than I got from the factory firmware.
From the same computer, if I do a snmpwalk towards an older rut955 (very old firmaware), I do get plenty of answers.
But to the new rutx11,I only get the very short (and limited) tree as shown in my question.
I am a novice on SNMP so maybe I am doing something wrong?
Just for my understanding, your answer was it a general one or does it actually work on your unit? I.e. can you see all variables as described in the manual?
