OpenFlow configuration

Post by MarianaCruz »

Hello,

I'm trying to enable and configure OpenFlow in my OS6250-24 switch but it doesn't even recognize the command "openflow".. Any idea why? What should I do? I saw that the switch is compatible with openflow and I simply want to connect it to an SDN controller.

The commands im tryign to run are for example:

openflow logical-switch vswitch1 mode normal version 1.3.1 vlan 5
openflow logical-switch vswitch1 controller 1.1.1.1
openflow logical-switch vswitch1 interfaces port 1/3


And when I add the first command the switch returns the error:
-> openflow logical-switch vswitch1 mode normal version 1.3.1 vlan 5
^
ERROR: Invalid entry: "openflow"

The show microcode command returns:
-> show microcode

Can you please help??

Very appreciated!

Hi,
you need at the switch at least 6.6.5
6.6.1 is very old.

Hi Silvio,

Thanks for your reply. I understood that and upgraded the switch, but now when i connect it to ONOS controller some errors appear.

The commands that i put on the OS-6250 were:

Code: Select all

openflow logical-switch vswitch mode api version 1.0/1.3.1
openflow logical-switch vswitch controller 192.168.1.127

Also in both versions, ONOS is able to detect all ports of the switch, but in 1.3.1 due to the errors, ONOS is not able to detect the hosts connected to the switch. On the other hand, in version 1.0 ONOS detects the hosts but right after detection it disconnects from ONOS. Any idea what this means?

Please i could really use the help!

Thanks in advance :)

sorry, but I never used Openflow by myself (only infos from the switch management and cli guides). So you have to open a ticket at alcatel.
