Hi,

I am trying to connect an OpenWRT CC router to an ONOS Controller (laptop running ubuntu). I get below error. ONOS then prints error in the log - "disconnecting switch due to read timeout".

I need help in resolving this-

How to stop trying connection with 127.0.0.1
Signal 11 error

Thank You.

Not sure about other issues but below logs: Sep 18 22:52:06|00004|dp_acts|WARN|can't directly forward to input port. Sep 18 22:52:06|00005|fault|EMER|Caught signal 11.

are due to your openflow rules. Some of your rules are trying to send incoming packet to the incoming port itself. May be this case is not handled well and causing segmentation fault. You can debug it by setting "ulimit -c unlimited" and run core file in gdb.
