Re: [nv-l] mlm on nt docs

he there Karl :
I have some experience (in fact a real pain) with MLM and netview on 
Windows and Linux. there are lots of problems generated mostly by the 
lack of "MLM support " on those platforms but also because of the design.
on Linux: on every snmp poll netmon must do some snmp sets to every MLM 
in your network (for update configuration ). for example it sets the 
table with discovered nodes, destination of traps etc. but there is a 
mistake in setting the IP+port  for trap destination: it must be netview 
IP +162/tcp and it is netview IP + 41472/tcp (becaue of a programming 
mistake) ..there is a PMR for this and the problem will be  corrected in 
the next version. so the risk is to never receive traps from any MLM! ( 
I did a small script that change that MIB from time to time on all MLM's 
in the MLM smartset)
on Windows netview polles MLMs but never does sets! (again it's about 
netmon design) ... anyway now is functioning quite good...
so all we have to do is to wait for the next version hoping IBM will 
provide full functionallity at least to LINUX netview!! (they are 
allways saying how much they are supporting LINUX) MLM, RIM, APM and so 
on and so on....
