HI, I sent a Question (below) regarding the openflow VLAN problem but I didnt get the right answers...The solution is to add a flow entry for the switch from the NOX controller using ovs-ofctl tool.
I issued this command as follow: ovs-ofctl add-flow tcp:10.75.116.129:6633 "priority=32769,idle_timeout=240,ip,nw_dst=192.178.22.6, nw_src=192.178.22.7,action=output:23" Where: 10.75.116.129 is HP 5406zl IP address 192.178.22.6 and 192.178.22.7 are the ip address of openflow VLAN PCs. After enabling the openflow and connecting the switch to the NOX controller, I wont be able to Ping these 2 PCs unless I add a flow entry to the switch. I issued the ovs-ofctl command and I checked the flow entries on the switch as follow: #show openflow 35 flows and I got: Flow 1 Incoming Port : 0 HW acceleration : Yes Destination MAC : 000000-000000 Source MAC : 000000-000000 VLAN ID : 0 VLAN Priority : 0 Source IP : 192.178.22.7 Destination IP : 192.178.22.6 IP Protocol : IP IP ToS bits : 0 Source Port : 0 Destination Port : 0 Duration : 6s secs Priority : 32769 Idle Timeout : 240 secs Hard Timeout : 0 secs Packet Count : 0 Bytes Count : 0 Actions : output:4 but still I am not able to ping the two PCs and I can't see the MAC address of them as shown above. I am doing the right ovs-ofctl command. Please Help.. Thank you ============== I implemented an openflow network using the following devices: 1- HP Switch which has Openflow version 2.02w 2-Ubuntu 12.04 which has latest version of NOX controller I followed the steps of installing openflow in HP Switch from this supplement: http://h20000.www2.hp.com/bc/docs/support/SupportManual/c03170243/c03170243.pdf the controller is working properly and everything seem to be fine. I created a separate VLAN for openflow in HP switch and I connected some computers to this VLAN. When I start enabling openflow in this VLAN, these computers will be discconected from the network and I will not be able to ping them unless I disable openflow.These Two PCs can ping each other but they can't ping the HP switch and the controller. I can ping the openflow switch VLAN IP address from any VLAN. The Controller is in separate VLAN. I tried to move the controller to openflow vlan but after enabling openflow in the switch, the switch will not be able to connect to the controller. Summary: HP Switch: VLAN 35 Controller: VLAN 117 Test PCs: VLAN 35>>> will be isolated from the network after pinging....cannot ping any device in the network and cannot be pinnged,but can ping each other. ==============
