Each Group table entry has four fields. The first field is a Group Identifier, which is a 32-unsigned integer that uniquely identified the group.

WebOpenFlow explicitly specifies forwarding actions. Thus, a flow with an empty set of actions does not forward packets anywhere, causing them to be dropped. You can specify an empty set of actions with actions= on the ovs-ofctl command line. For example: $ ovs-ofctl add-flow br0 priority=65535,actions=.
