I think that OVS is working as OFspec.
"7.3.4.2 Modify Group Entry Message" of OFspec1.3.4 says:
When the bucket is selected for a packet,
its actions are applied to the packet as an action set.
and,
"5.10 Action Set" of OFspec1.3.4 says:
When an action of a specific type is added in
the action set, if an action of the same type exist,
it is overwritten by the later action.
How is the following?
{
"dpid": 0000000000000001,
"type": "ALL",
"group_id": 1,
"buckets":
[
{
"actions":
[
{
"type": "OUTPUT",
"port": 3
}
],
},
{
"actions":
[
{
"type": "OUTPUT",
"port": 2
}
],
}
]
}
