Request configuration for Nstream Dual

Can someone please post a configuration for dual nstream. I have been unable to get a pair of RB333’s to link in dual mode. I can get a single nstream interface going no problem, but when I try to bring up a second radio pair the performance of both goes in the tank, so, trying dual nstream I am unable to achieve even a link between the radios. Help is appreciated.

This should do it:
