Hi,
The match field is in your Packet-In, but it has only "in_port" field.
Match
Type: OFPMT_OXM (1)
Length: 12
OXM field
Class: OFPXMC_OPENFLOW_BASIC (0x8000)
0000 000. = Field: OFPXMT_OFB_IN_PORT (0)
.... ...0 = Has mask: False
Length: 4
Value: 10
Pad: 00000000
Pad: 0000
It corresponds to the output of Ryu.
switch=1 buffer_id=ffffffff total_len=60 reason=ACTION table_id=0 cookie=0
*match=OFPMatch(oxm_fields={'in_port': 10})*
pkt=ethernet(dst='00:00:de:ad:be:ef',ethertype=2048,src='00:00:de:ad:be:ef'),
ipv4(csum=46560,dst='2.2.2.2',flags=0,header_length=5,identification=0,offset=0,option=None,proto=0,src='1.1.1.1',tos=4,total_length=20,ttl=255,version=4)
Ryu does only parsing packets, so your situation should be due to your
switch, I guess.
Thanks,
Fujimoto

The switch is hosted in Mininet, the controller is hosted locally and
they talk to each other via virtualbox. Dump shows the controller
receives a match object with the packet_in. Any tips as to where I can
look next?

Hi, Frode
It is probably due to the implementation of your switch.
Could you use network analyzer, like Wireshark?
If you cannot see any match field in the PacketIn,
Your situation is due to your switch.
Please ask the help team of your switch.
Thanks,
Fujimoto

Hello,
I am currently testing out Ryu and cant seem to get the hang of the
flow table matching. I am doing a rather basic example with one
switch and one rule. I am sending out the packet with OFPP_TABLE
action from the controller. Why am I seing a packet in reason of
action, but when parsing the incoming packet and looking at the
OFPMatch object it states "(oxm_fields={'in_port': 10})" and not the
match object from the flow table entry (see below)? Any help is
highly appreciated.
