Hi Nick, At one point it time when the system that fv was on was really bogged down I was able to do show openflow 1750 and it said backoff, idle, connecting, backoff but now that I have restarted flowvisor I can't seem to catch it. When this message prints from nox I quickly hit entry on show openflow 1750 but I still says active.
The switch in question here is 130.127.39.131 At the machine running FV I have this going: while [ 1 -eq 1 ] ; do netstat -a | grep "39.131" | grep ESTAB -v ; done tcp6 0 0 expedient.clemson.:6633 130.127.39.131%13:35160 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%13:62919 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%14:35160 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%14:62919 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%15:35160 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%15:62919 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%15:35160 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%15:62919 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%14:35160 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%14:62919 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%15:35160 TIME_WAIT tcp6 0 0 expedient.clemson.:6633 130.127.39.131%15:62919 TIME_WAIT It seems the TCP connect gets to the TIME_WAIT state so the connection between the switch (130.127.39.131) actually closed. (netstat seems to hang for a while so I didn't catch anything else. Also everything I pasted above is what came out of netstat after the error occurred and after that flashed it was able to go to ESTABLISHED again. P.S: Any idea why its using tcp6 sockets? It has a ipv4 address.
