2920 no clients recognized

mertdemi — Wed, 20 Aug 2014 15:56:50 GMT

Hi there

I have installed controller 2.3.6 and optimizer 1.2
I have successful connection to lync and can see lync sessions on controller.

i have also enabled netflow on controller v 1.3 and passive mode.

But i cannot see clients on topology map.
switch is shown correctly.

when i check from switch it also shows connection to controller.

because of this problem i can not assign dscp values to clients.

also clients were working very slow until we increased hardware limit which was 0 by default.

is there anything that needs to be done to recognize clients?

Regards

Hello mertdemi,

Could you please provide answers to the below questions:

Is the client sending any traffic to the OpenFlow switch? If yes, what traffic ?
What are the rules programmed in the OpenFlow switch ? Does it have any rules other than the default rules installed by the controller ?
Does the controller receive the packet_in messages from the switch ?

Thanks,
