Adding flows with action type "group"

Hi,

I have a trouble adding a flow with action type "group", both via the HP VAN controller and Rsdoc. I will just use the Rsdoc one to ask my question.

I go to:

https://<controller_IP>:8443/api

and use this api to add a flow:

/of/datapaths/<my_dpid>/flows

{"flow": {
"priority": 3,
"table_id": 0,
"idle_timeout": 60,
"match": [
{"ipv4_src": "10.0.0.1"},
{"ipv4_dst": "10.0.0.22"},
{"ip_proto": "tcp"},
{"eth_type": "ipv4"},
{"tcp_dst": "80"}
],
"instructions": [{"apply_actions": [{"group": 101}]}]
}}

This gives me an error

{
  "error": "java.lang.IllegalArgumentException",
  "message": "{ofm:[V_1_3,ERROR,76,4959],BAD_ACTION/BAD_TYPE,#dataBytes=64,OFM-cause:[V_1_3,FLOW_MOD,104,4959]}"
}

Adding a flow entry with {"apply_actions": [{"output": 10}]} works fine. Does this mean the physical switch I am using does not support adding a flow entry with an action type "group"? I figured out the controller supports it by viewing:

https://<controller_ip>:8443/sdn/v2.0/models

FYI, listing the group entries displays this (this shows that I was able to insert group table entries):

/of/datapaths/<my_dpid>/groups

{
  "version": "1.3.0",
  "groups": [
    {
      "id": 100,
      "type": "all",
      "buckets": [
        {
          "weight": 0,
          "watch_group": 4294967295,
          "watch_port": 0,
          "actions": [
            {
              "output": 23
            }
          ]
        }
      ]
    },
    {
      "id": 101,
      "type": "all",
      "buckets": [
        {
          "weight": 0,
          "watch_group": 4294967295,
          "watch_port": 0,
          "actions": [
            {
              "output": 23
            }
          ]
        }
      ]
    }
  ]
}

Solved.

If anyone else is having a same problem, use "write_action" instead of "apply_action" in the instruction set.

e.g.,

...

"instructions": [{"write_actions": [{"group": 101}]}]

...
