Hi, Sorry for the cross-posting, not sure what's the most appropriate list.
i use OpenFlow 1.0 (reference impl) and nox-zaku. By default, both ofprotocol and nox will start with a keep-alive of 15 secs. After a few minutes of inactivity, the switch side disconnects, sending a tcp request and complaining as follows : Feb 15 02:02:04 172.24.74.231 sysinit: Feb 15 02:02:04|02563|rconn|ERR|tcp: openflow3.stanford.edu:6633: no response to inactivity probe after 15 seconds, disconnecting I changed nox keep-alive to 10 secs and ofprotocol to 20. I don't see any resets at that point, but I am still confused with the switch sending ECHO_REQUESTs. I was expecting that since it receives requests from nox, it will consider the connection ACTIVE, thus not sending any keep-alives on its own. Instead it keeps sending "echo requests" every 20 secs. What's the intended behavior of rconn/vconn here? I suspect that this is related with the periodic disconnects I mentioned earlier. Note that this happens only when there is no traffic in the channel (aka no LLDP or any other packets). Srini, is this related with what we've seen with the circuit-aggregation/flowvisor setup? Thanks, Yiannis
