Get flows stats filtered by fields

Get flows stats of the switch filtered by the OFPFlowStats fields. This is POST method version of Get all flows stats.

Usage:

Method POST
URI /stats/flow/<dpid>

Request message body:

Attribute Description Example Default
table_id Table ID (int) 0 OFPTT_ALL
out_port Require matching entries to include this as an output port (int) 2 OFPP_ANY
out_group Require matching entries to include this as an output group (int) 1 OFPG_ANY
cookie Require matching entries to contain this cookie value (int) 1 0
cookie_mask Mask used to restrict the cookie bits that must match (int) 1 0
match Fields to match (dict) {“in_port”: 1} {} #wildcarded
priority Priority of the entry (int) (See Note) 11111 #wildcarded

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.

Response message body:

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",
                "port": 1
            }
        ]
     }' 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.
