There is a problem connecting between a controller and a switch which uses OF-DPA.

Hello, I'm Jake Kim and I am beginner in SDN.
Since I wanted to use OF-DPA in ODL, I asked how to connect the switch in controller last month.
After I installed the 'odl-openflowplugin-flow-services-rest’ in controller, I could make connection with switches.
However, the connection was terminated immediately.
The OpenFlow I used is 1.3 version, and the ODL I used is Oxygen-SR1 (karaf-0.8.1).  
The log in the switch is as follows.

01-02 03:15:36.298519 [ofconnectionmanager] cxn 163.152.20.50:6653: DISCONNECTED->CONNECTING

You can see that there are some wrong with meter and group request packets.

The switches continue to repeat the above steps.

So, I turned on the wireshark in the controller.

This is a part of OFPT_FEATURES_REPLY packet which the switch send to the controller after they give and take the HELLO packets. 


    .... .... .... .... .... .... .... ...1 = OFPC_FLOW_STATS: True

    .... .... .... .... .... .... .... ..1. = OFPC_TABLE_STATS: True

    .... .... .... .... .... .... .... .1.. = OFPC_PORT_STATS: True

    .... .... .... .... .... .... .... 0... = OFPC_GROUP_STATS: False

    .... .... .... .... .... .... ..0. .... = OFPC_IP_REASM: False

    .... .... .... .... .... .... .1.. .... = OFPC_QUEUE_STATS: True

    .... .... .... .... .... ...0 .... .... = OFPC_PORT_BLOCKED: False


There is no information about meter feature, but the switch has stated that it cannot handle the Group stats request!

Nevertheless, the controller kept asking the switch to Group feature stats.

How can I fix this problem?

Could I turn off some option to prevent the controller from checking the Group and Meter features in advance?
