Hi,
All you have to do now is the use the orion Network performance monitor(under start/progs/orion)
and click on NEW from the options in the top left of the screen.
This will enable you to add add new node and to put in the community string.
Once you have done this it will show the device and all of it's interfaces.
You then check the interfaces that you want to monitor and click ok.
That should be it
