Hi,
To get more log messages, how about adding "--verbose" option to ryu-manager?
On my environment, the following errors ware shown.
$ ryu-manager --verbose myapp.py
...
EventOFPErrorMsg received.
version=0x4, msg_type=0x1, msg_len=0x4c, xid=0xe3ab9a29
`-- msg_type: OFPT_ERROR(1)
OFPErrorMsg(type=0x2, code=0xa,
data=b'\x04\x0e\x00\x68\xe3\xab\x9a\x29\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x80\x00\xff\xff\xff\xff\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x00\x14\x00\x01\xd2\x04\x00\x00\x00\x00\x80\x00\x00\x04')
|-- type: OFPET_BAD_ACTION(2)
|-- code: OFPBAC_MATCH_INCONSISTENT(10)
`-- data: version=0x4, msg_type=0xe, msg_len=0x68, xid=0xe3ab9a29
`-- msg_type: OFPT_FLOW_MOD(14)
My OVS version may not support contrack though...
Thanks,
Iwase
