Hi all,
I built an Packet_in packet with LLDP, and send it from a controller to
another controller. When I parse the packet, I can get PacketIn packet with
data. But the data is Not LLDP packet.
When parse data ,I get LLDPUnknownFormat exception. The packet information show
below.

We can find out that there is LLC in protocols in protocols.
The ethernet type is 534, which is the same with the LLDP chassis_id?? s
typelen??534.
What should I do?
Thank you for your time.
