You have to configure OVS to use OF 1.3 instead of OF1.0. By default OVS uses OF1.0. > And with OVS 1.10.0 (installed localy) I get: > > error msg ev version: 0x4 msg_type 0x1 xid 0xd49cfa2a type 1 code 1 > data ?????* type 0x1 code 0x1 Althouh you set OVS to use OF1.3 somehow, OVS doesn't support OFPQueueGetConfigRequest yet. OVS returns an error message in respond to the request. type 0x1 = error code 0x1 = bad request > But with the following changes and the softswitch from here: > https://github.com/CPqD/ofsoftswitch13 everything works as expected > > diff --git a/ryu/ofproto/ofproto_v1_3_parser.py > b/ryu/ofproto/ofproto_v1_3_parser.py > index 3f2d020..cace1aa 100644 > --- a/ryu/ofproto/ofproto_v1_3_parser.py > +++ b/ryu/ofproto/ofproto_v1_3_parser.py > @@ -2734,7 +2734,7 @@ class OFPPacketQueue(MsgBase): > @classmethod > def parser(cls, buf, offset): > (msg.queue_id, msg.port, msg.len) = struct.unpack_from( > - ofproto_v1_3.OFP_PACKET_QUEUE_PACK_STR, buf, offset) > + ofproto_v1_3.OFP_PACKET_QUEUE_PACK_STR, buffer(buf), offset) > > length = ofproto_v1_3.OFP_PACKET_QUEUE_SIZE > offset += ofproto_v1_3.OFP_PACKET_QUEUE_SIZE See below. > @@ -2766,7 +2766,7 @@ class OFPQueueGetConfigReply(MsgBase): > > msg.queues = [] > offset += ofproto_v1_3.OFP_QUEUE_GET_CONFIG_REPLY_SIZE > - while offset < msg.length: > + while offset < msg_len: This line looks good. > queue = OFPPacketQueue.parser(buf, offset) msg.buf should be passed.
