.. _get-flows-stats-filtered:

Get flows stats filtered by fields
----------------------------------

    Get flows stats of the switch filtered by the OFPFlowStats fields.
    This is POST method version of :ref:`get-all-flows-stats`.

    Usage:

        ======= ===================
        Method  POST
        URI     /stats/flow/<dpid>
        ======= ===================

        ============ ================================================================== =============== ===============

        .. NOTE::

           OpenFlow Spec does not allow to filter flow entries by priority,
           but when with a large amount of flow entries, filtering by priority
           is convenient to get statistics efficiently.
           So, this app provides priority field for filtering.

Example of VLAN ID match field
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    The following is available in OpenFlow1.0 or later.

    - To match only packets with VLAN tag and VLAN ID equal value 5::

        $ curl -X POST -d '{
            "dpid": 1,
            "match":{
                "dl_vlan": 5
            },
            "actions":[
                {
                    "type":"OUTPUT",
                    "port": 1
                }
            ]
         }' http://localhost:8080/stats/flowentry/add

    .. NOTE::
        When "dl_vlan" field is described as decimal int value, OFPVID_PRESENT(0x1000) bit is automatically applied.

    The following is available in OpenFlow1.2 or later.

    - To match only packets without a VLAN tag::

        $ curl -X POST -d '{
            "dpid": 1,
            "match":{
                "dl_vlan": "0x0000"   # Describe OFPVID_NONE(0x0000)

            "actions":[
                {
                    "type":"OUTPUT",
                    "port": 1
                }
            ]
         }' http://localhost:8080/stats/flowentry/add

    - To match only packets with a VLAN tag regardless of its value::

        $ curl -X POST -d '{
            "dpid": 1,
            "match":{
                "dl_vlan": "0x1000/0x1000"   # Describe OFPVID_PRESENT(0x1000/0x1000)
            },
            "actions":[
                {
                    "type":"OUTPUT",
                    "port": 1
                }
            ]
         }' http://localhost:8080/stats/flowentry/add

    - To match only packets with VLAN tag and VLAN ID equal value 5::

        $ curl -X POST -d '{
            "dpid": 1,
            "match":{
                "dl_vlan": "0x1005"   # Describe sum of VLAN-ID(e.g. 5) | OFPVID_PRESENT(0x1000)
            },
            "actions":[
                {
                    "type":"OUTPUT",

                }
            ]
         }' http://localhost:8080/stats/flowentry/add

    .. NOTE::
        When using the descriptions for OpenFlow1.2 or later, please describe "dl_vlan" field as hexadecimal string value,
        and OFPVID_PRESENT(0x1000) bit is NOT automatically applied.
