Notice how it asked if there was a netserver running on localhost?  That 
implies that it didn't know you wanted the control connection to go to 
10.1.202.155.  I suspect that happened because you used "-h" rather than 
the correct "-H" option.  However, I would have expected the option 
parsing part of netperf to have hit the "-h" and emitted the help text 
and exited.

Anyway, my first suggestion would be to try "-H" rather than "-h" and 
see what you get.

happy benchmarking,
