[ovs-discuss] OVS-OFCTL - negotiated OpenFlow version

Wed May 6 21:52:16 UTC 2015

Hello,

I am trying to update the status of one of the port using following command
-

data2 # ./ovs-ofctl mod-port  vlan20-odl sp4 up

And I got following error message ...

2015-05-06T20:52:49Z|00001|vconn|WARN|unix:/usr/local/var/run/openvswitch/vlan20-odl.mgmt:
version negotiation failed (we support version 0x01, peer supports version
0x04)
ovs-ofctl: vlan20-odl: failed to connect to socket (Protocol error)

As suggested on some mailing list, I added openflow versions as follows -

./ovs-vsctl set bridge vlan20-odl
protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13,OpenFlow14,OpenFlow15

and then again update the port ..

./ovs-ofctl --verbose mod-port  vlan20-odl sp4 up

In the logs, I see that --

2015-05-06T21:39:55Z|00015|vconn|DBG|unix:/usr/local/var/run/openvswitch/vlan20-odl.mgmt:
negotiated OpenFlow version 0x01 (we support version 0x01, peer supports
version 0x06 and earlier)

My question is -

1. Why the negotiated OF version is 1 (not 1.4) when peer (OpenDayLight )
can support higher version
2 How can I make  trained OVS to communicate using higher version of OF ..

3. Why I still don't see port status getting update , Am I missing
something ?

Thanks
