Following things are setup, for future refrence.

Client side Configuration
The conf file send_nsca.cfg on client side must contain same parameter.
password= ******
decryption=1
Testing command from client side. ( send_nsca -H 10.131.11.142 -p 5667 -c /usr/local/nagios/etc/send_nsca.cfg )
Or we can try with script.
