Hello.

When debug output is activated (3800 KA.15.15.0006):

debug openflow 
debug destination session

I am receiving errors (but message is processed):

0000:19:07:48.46 OPFL eOFNetTask:RX from tcp:192.168.56.7:6633: 0:
   OFPT_PACKET_OUT (OF 0x04) (xid=0x188e): ***decode error: OFPBRC_BAD_LEN***

I capture packet (xid=0x188e is 6286) (also attached PACKET_OUT.pcapng):

I check specification ("OpenFlow Switch Specification Version 1.3.1 (Wire Protocol 0x04)" appendix A), but cannot find any error :-(

- TCP len = 109

- OF len = 109 = 24 (struct ofp_packet_out) + 16 (struct ofp_action_output) + data 69 (14 (L2 header) + 55 (LLDP))

Is it the minor bug (only debug output bug) in firmware or something is bad ?

Thanks, Martin Cerveny

Hello Martin Cerveny,

Thanks for your query.
We will get back to you shortly.

Thanks,
HP SDN Team

Hello,

Can you please send the full debug output from the switch - starting at the creation of the flow.

Keep the same debug switches that you used.

And can you also include a wireshark capture of that same test?

Thank you,

Scott

Hello.

The same packet is captured by wireshark & switch debug output (no mode erros show) & packet trace by SDN VAN CTLR added in original post. I will not setup test enviroment near feature.
