M4300 OpenFlow Configuration

Hello Everyone, 

I am using the M4300 switch -- to implement the openflow protocol. The SDN Controller I am using is ONOS. I am having a simple linear topology which is I have connect SDN controller (10.18.206.12) to network and the Netgear M4300 switch (Managment ip is 10.18.206.18) is connected to SDN using OOB, I have configured two host with static-ip (10.18.206.14 and 10.18.206.16 respectively). All with subnet as 255.255.255.0

When I enable the openflow the ping between two is not reachable. But the switch can reach the SDN controller and vice-versa. But the host 1 and host 2 are not reachable. Though both the host are visible on the SDN controller topology as hosts.

Also, I am able to add flows in switch.

I have tried all the CLI commands mentioned in the manual. Still I am not getting desired output. I would like if anyone can give any input and help me to solve this problem of mine. 

Please, let me know what can be done. Thank you!
Highly appreciated.
