Hello everybody, I don't know if it is a relevant question to ask here: I am trying to do OpenFlow topology discovery (with pox) in real testbed called OFELIA. I've chosen some switches form one of the island to run the test. After I did all the settings, the controller started to work and detect the switches and links between them. However, in the meantime there are some openflow error messages and warnings as well. These errors are as follow:
""" ERROR:openflow.of_01:[00-00-00-00-00-02|512 2] OpenFlow Error: [00-00-00-00-00-02|512 2] Error: header: [00-00-00-00-00-02|512 2] Error: version: 1 [00-00-00-00-00-02|512 2] Error: type: 1 (OFPT_ERROR) [00-00-00-00-00-02|512 2] Error: length: 28 [00-00-00-00-00-02|512 2] Error: xid: 0 [00-00-00-00-00-02|512 2] Error: type: OFPET_BAD_REQUEST (1) [00-00-00-00-00-02|512 2] Error: code: OFPBRC_BUFFER_UNKNOWN (8) [00-00-00-00-00-02|512 2] Error: datalen: 16 [00-00-00-00-00-02|512 2] Error: 0000: 01 0d 00 10 00 00 00 18 9e 11 2d 2c 00 06 00 00 |..........-,....| """ """ INFO:packet:(lldp tlv parse) warning TLV data too short to parse (86) INFO:packet:(lldp parse) error parsing TLV """ Would you please help me with that? I would like to know if anyone had this problem before and what makes this problem to happen and if I can solve it or not? Thank you all. Farzaneh
