Demand poll is a complex process and there are several places it could go wrong,
but you have to start by telling us exactly where and how it fails. Does the
window open from the GUI? That has to happen first. If not, try running
nmdemandpoll from the command line (the man page will tell you how) and see if
that works. If so, then you may have an X-resource problem or you may need to
make sure that you have issued the ulimit commands before running the GUI to
remove any artificial limits on what your user id can do. If the window starts,
but nothing comes in it, then you should probably look elsewhere. When you
select a node and then click "demand poll" that starts an xnmappmon process,
which sends a trap to trapd with the name of the node in it to be demand polled.
This trap is sent by trapd to netmon, who does the operation, and sends the
results back to xnmappmon for display. If the window opens, can you see the
trap in the trapd.log? One of the things that can go wrong here is that demand
poll will hang in the middle of a "trap storm" when traps are coming in at a
high rate. You might look at trapd.log to determine that, though at really high
rates trapd will be unable to process any traps, only queue them, and you won't
see that unless you turn on the trapd.trace (issue trapd -T from the command
line to toggle the trace on or off). Finally, if you see the trap, then you
will have to turn on the netmon trace to see what netmon does when he receives
it (netmon -M 31).
If all this makes you uncomfortable, then I would call Support and get some
help.
But I don't see that set community strings have anything to do with demand poll.
The code most definitely does not use anything but the read string. You should
be able to get the same results yourself with snmpget that netmon gets when he
does it.
