Re: I CAN NOT VIEW END HOST ON THE GUI
Hi Mo,
The most common reason for this condition is that you've set up a looped mininet topology, but the VAN SDN controller has been configured with hybrid.mode=true (default setting). When hybrid.mode=true, VAN will delegate forwarding decisions to the controlled switches, except for the packets it wants to see. Since VAN doesn't capture ping packets, the ping packets are forwarded through the looped topology. Essentially, with hybrid.mode=true VAN is relying on the controlled switches to resolve loops (via a traditional protocol like spanning-tree), but the mininet switches do not resolve loops.
If this matches what you're seeing, you'll need to change the VAN setting to hybrid.mode=false and restart the sdnc process.
