I don't quite understand, and perhaps I am not the right person to 
respond, as this is not my area of expertise.
But originally you said demand poll timed out but snmpwalk did not.  Now 
you are saying that they both work, but one returns something the other 
does not.  That's a big difference in my book. 

I don't know what is going on, and I am not certain that anyone could 
without a detailed analysis of what you get back in each case, but demand 
poll asks for certain specific SNMP information, while snmpwalk just 
starts at a certain value and does SNMP Get Next requests until the agent 
indicates there is nothing more to get.  So offhand, it sounds to me like 
a router configuration problem, as though this 4th interface is in one 
table on the router, which you can see with snmpget, but not in the tables 
that netmon specifically queries with demand poll.  Not being very netmon 
savvy, I cannot tell you what those are.  So I am done at this point.  But 
if you want someone to look at this in detail, I'd suggest you capture the 
output and call Support.

 The nmdemandpoll brings out the same information, like the GUI-demand 
poll:
 I can see a Router with 3 Interfaces ,what I miss is a fourth existing
 interface.
 The SNMP Connectivity Test is successful.
 With a snmpwalk from the command line I can see an interface definition.
 I reach the interface with a ping.

 What else could help?
