Hello, Everyone.
In ryu/topology/swiches.py.
there is a code snippet I don't understand the meaning clearly, just
as follows:
> @staticmethod
> def _drop_packet(msg):
> buffer_id = msg.buffer_id
> if buffer_id == msg.datapath.ofproto.OFP_NO_BUFFER:
> return
>
> dp = msg.datapath
> # TODO:XXX
> if dp.ofproto.OFP_VERSION == ofproto_v1_0.OFP_VERSION:
> dp.send_packet_out(buffer_id, msg.in_port, [])
> else:
> LOG.error('cannot drop_packet. unsupported version. %x',
>
> dp.ofproto.OFP_VERSION)
>
In the logic of "else" for none-OF_VERSION_1.0:
WHY does this program snippet call "Log.error()" and show the
message of "cannot drop packet, unsupported version."?
Is it a Bug?
BTW, when I use the CPQD1.3 switches to have a test of My App, My
Console print these error message frequently. So I issue these
question.
