Hi, I have two tp-link1043nd switches flashed with openflow and connected with trunk. I set up a floodlight controller with IP =192.168.100.1 and connect to one of these two switches. Topology: S1---C1---S2
The problem is : Only one switch can connect to the controller at the same time. Once another switch connect to the controller, the previous one will be disconnected. If I send the packet from the disconnected switch, the controller will miss the packet.... In the controller, I only show the message and do not add any action. If the topology only has one switch, it doesn't have this problem. The following is the error message: 11:03:42.592 INFO [n.f.c.i.OFChannelHandler:New I/O server worker #2-4] New switch connection from /192.168.100.1:60059 11:03:42.626 INFO [n.f.d.DebugCounter:New I/O server worker #2-4] Counter exists for net.floodlightcontroller.core/00:00:00:23:20:98:43:3b -- resetting counters 11:03:42.627 INFO [n.f.d.DebugCounter:New I/O server worker #2-4] Counter exists for net.floodlightcontroller.core/00:00:00:23:20:98:43:3b/pktin -- resetting counters 11:03:42.627 INFO [n.f.d.DebugCounter:New I/O server worker #2-4] Counter exists for net.floodlightcontroller.core/00:00:00:23:20:98:43:3b/write -- resetting counters 11:03:42.627 INFO [n.f.d.DebugCounter:New I/O server worker #2-4] Counter exists for net.floodlightcontroller.core/00:00:00:23:20:98:43:3b/pktin/drops -- resetting counters 11:03:42.627 INFO [n.f.d.DebugCounter:New I/O server worker #2-4] Counter exists for net.floodlightcontroller.core/00:00:00:23:20:98:43:3b/write/drops -- resetting counters 11:03:42.627 INFO [n.f.c.i.OFChannelHandler:New I/O server worker #2-4] Switch OFSwitchBase [/192.168.100.1:60059DPID[00:00:00:23:20:98:43:3b]] bound to class class net.floodlightcontroller.core.internal.OFSwitchImpl, writeThrottle=false, description Switch Desc - Vendor: Stanford University Model: Reference Userspace Switch Make: OpenWrt pid=1724 Version: 1.0.0 S/N: None 11:03:42.635 INFO [n.f.c.OFSwitchBase:New I/O server worker #2-4] Clearing all flows on switch OFSwitchBase [/192.168.100.1:60059 DPID[00:00:00:23:20:98:43:3b]] 11:03:42.636 WARN [n.f.c.i.C.s.notification:main] *Switch 00:00:00:23:20:98:43:3b connected.* 11:03:42.673 WARN [n.f.l.i.L.s.notification:New I/O server worker #2-3] Link added: Link [src=00:00:00:23:20:98:43:3b outPort=2, dst=00:00:00:23:20:46:85:5b, inPort=2] 11:03:42.674 WARN [n.f.l.i.L.s.notification:New I/O server worker #2-3] Link added: Link [src=00:00:00:23:20:46:85:5b outPort=2, dst=00:00:00:23:20:98:43:3b, inPort=2] 11:03:42.675 WARN [n.f.l.i.L.s.notification:New I/O server worker #2-3] Link added: Link [src=00:00:00:23:20:98:43:3b outPort=3, dst=00:00:00:23:20:46:85:5b, inPort=3] 11:03:42.676 WARN [n.f.l.i.L.s.notification:New I/O server worker #2-3] Link added: Link [src=00:00:00:23:20:46:85:5b outPort=3, dst=00:00:00:23:20:98:43:3b, inPort=3] 11:03:42.677 WARN [n.f.l.i.L.s.notification:New I/O server worker #2-3] Link added: Link [src=00:00:00:23:20:98:43:3b outPort=4, dst=00:00:00:23:20:46:85:5b, inPort=4] 11:03:42.678 WARN [n.f.l.i.L.s.notification:New I/O server worker #2-3] Link added: Link [src=00:00:00:23:20:46:85:5b outPort=4, dst=00:00:00:23:20:98:43:3b, inPort=4] *11:03:42.683 ERROR [n.f.c.i.OFChannelHandler:New I/O server worker #2-3] Disconnecting switch OFSwitchBase [/192.168.100.1:58322 <http://192.168.100.1:58322/>DPID[00:00:00:23:20:46:85:5b]] due to IO Error: Connection reset by peer* 11:03:42.684 INFO [n.f.c.i.OFChannelHandler:New I/O server worker #2-3] Disconnected switch OFSwitchBase [/192.168.100.1:58322 DPID[00:00:00:23:20:46:85:5b]] 11:03:42.684 WARN [n.f.c.i.C.s.notification:main] *Switch 00:00:00:23:20:46:85:5b disconnected.*
