About discovery? Yes, it discovers links. With no QoS information. See the POX manual for more on the discovery component. -- Murphy On Feb 17, 2015, at 9:29 PM, Murat Karakus wrote: > Thanks for quickly relpy, Murphy. I guess I need to use openflow.discovery > component as well like below

Thanks for quickly relpy, Murphy. I guess I need to use openflow.discovery component as well like below, right? ./pox forwarding.l2_multi openflow.spanning_tree openflow.discovery How about my other question? - For this purpose, I want my controller (POX) to discover all switches (w/

l2_multi is an example that does shortest paths between endpoints (it uses Floyd-Warshall instead of Dijkstra's, but that's just a detail). And the spanning_tree component doesn't disable entire ports, IIRC -- just flooding on those ports. So if you have loops and use l2_multi and spanning_tre

2015-02-17 Thread Murat Karakus
Hi All, I am trying to implement a network having loops (e.g. 4 switches connected to each other and one host connected to each switch). When I try to ping a host, it does not work because of the loops. Using spanning_tree component may work in this case but I don't want it since it deletes a port
