From: discuss [mailto:discuss-boun...@openvswitch.org] On Behalf Of Advith Nagappa Sent: Wednesday, October 19, 2016 2:18 AM To: discuss@openvswitch.org Subject: [ovs-discuss] OVS + Mininet Hi , I was running mininet with userspace ovs (mn --switch user)(h1, h2 and s1) I notice that if i run ovs-vsctl show utility in a host, it does not show the topology. root@cep-VirtualBox:/home/cep# ovs-vsctl show 1ab72bfb-a279-47b1-9980-efd5aa8e2ab4 When I run mininet normally (mn) (h1, h2, s1) root@cep-VirtualBox:/home/cep# ovs-vsctl show 1ab72bfb-a279-47b1-9980-efd5aa8e2ab4 Bridge "s1" Controller "ptcp:6634" Controller "tcp:127.0.0.1:6633<http://127.0.0.1:6633>" is_connected: true fail_mode: secure Port "s1" Interface "s1" type: internal Port "s1-eth1" Interface "s1-eth1" Port "s1-eth2" Interface "s1-eth2" Is this the expected behavior? One would think that in both the cases the topology is the same, except that the userspace completely avoids the kernel datapath. What am I missing? [Sugesh] As discussed before in the previous mail, Have you had look at the ovs_vswitchd.log? This must be something to do with how mininet configures OVS, given that the the ping still works even after killing all the vswitch related process. Best Regards Advith Nagappa
