Hi Iwase,
Thank you for your prompt reply.
The problem with simple_switch.py because I wanna use it with OVX (which only
supports OF v1.0, so I'm using simple_switch.py).
With the new update on Ryu, you would receive a message similar to the one in
my previous email.
To get rid of this problem, I just rolled back to previous Ryu.
Cheers,
Talal

Hi Talal,
You mean at the following?
https://github.com/osrg/ryu/blob/master/ryu/app/simple_switch_13.py#L82
> AttributeError: 'NoneType' object has no attribute 'ethertype'
This error shows that the packet data contained in Packet-In message was
NOT an Ethernet frame or terribly truncated for parsing it, I guess.
(OpenFlow Spec 1.3 says the packet data contained in Packet-In message
should be an Ethernet frame.)
Was the packet data is other than an Ethernet frame?
OTOH, for the workaround, how about adding the following be for this
if statement?
e.g.)
pkt = packet.Packet(msg.data)
eth = pkt.get_protocols(ethernet.ethernet)[0]
if not eth:
# ignore non ethernet frame
return
if eth.ethertype == ether_types.ETH_TYPE_LLDP:
# ignore lldp packet
return
Thanks,
Iwase
