question about createSwitch

[sangyun-han]

Hi all

I am in the process of testing ONOS & OVX on real machine.

I already built ONOS environment and connected OpenVSwitch.

I want to make OVX Big switch with OpenVSwitchs but my plans keep falling through.

Because of 'createSwitch' part.

I identify OVS's DPID through ONOS controller, but OVX doesn't perceive these physical switch.

This is error log

python ovxctl.py -n createSwitch 1 00:00:00:00:00:00:04:9b,00:00:00:00:00:00:32:fc,00:00:00:00:00:00:04:dc,00:00:00:00:00:00:32:ba

{u'jsonrpc': u'2.0', u'id': u'ovxctl', u'error': {u'message': u'CreateOVXSwitch: Invalid DPID : One of the physical dpids that you have provided does not refer to a switch in the physical plane. DPID: 1179', u'code': -32602}}

This is information about ONOS controller's device

The 'normal' deployment model is to run ONOS on top of OVX. So you should connect your switches to OVX, and then create a virtual network that points to ONOS.

My question is that!

How do i connect switch to OVX without error message like this. ("One of the physical dpids that you have provided does not refer to a switch in the physical plane")

Do the error message mean that i have wrong DPID?

And, If i would be successful in connecting switch to OVX, Should i use [addControllers] command to connect ONOS controller?

,like this

Switch --- OVX -- ONOS

In Open Flow, the switch initiates the connection to the controller. So:

1) point your switch to OVX. When you use Open vSwitch, you do something like (BRIDGE is name of bridge, OVX_IP is IP address of OVX).

sudo ovs-vsctl set-controller BRIDGE tcp:OVX_IP:6633

Check the documentation for you hardware switch on how to configure OpenFlow.

2) point OVX to ONOS. First, create a virtual network, then create virtual switches

ovxctl.py -n createNetwork ONOS_IP SUBNET MASK

ovxctl.py -n createSwitch TENANT_ID DPIDS

Here, ONOS_IP is the IP address of ONOS, SUBNET and MASK specify the subnet for your virtual network. You can find the TENANT_ID in the response of the createNetwork call, and DPIDS is a list of the physical DPIDs you want (so the DPIDs of the Open vSwitches and the hardware switches).

Thanks marc ^^

I will try again
