Hi: https://github.com/onstutorial/onstutorial/wiki/Flowvisor-Exercise I did the first exercise in the website above, the result is the h1 can ping h3 but not h2 and h4as it said, but h2 can't ping h4, h1 and h3. when I removed the upper slice, then h2 can ping h4. I checked the slices and flowspaces, no mistake. The only difference is the controller I use is floodlight. each of the slice using a floodlight on different ports. I find there is error information in the controller connected to the lower slice:
22:08:54.276 ERROR [n.f.c.i.OFChannelHandler:New I/O server worker #2-3] Error OFPET_BAD_ACTION OFPBAC_EPERM from switch OFSwitchBase [/192.168.1.101:43902 DPID[00:00:00:00:00:00:00:04]] in state MASTER 22:08:54.276 WARN [n.f.c.i.Controller:New I/O server worker #2-3] Unhandled OF Message: ofmsg:v=1;t=ERROR;l=105;x=0 from OFSwitchBase [/192.168.1.101:43902 DPID[00:00:00:00:00:00:00:04]] does it matter? Could you help me?
