Want to use hardware flow-table on my HPE Openflow switch

Hi,

I want to use hardware flow-table on my HP openflow switch, but when I type command flow-location hardware-only, I get next message on the controller:

Do you know how to enable it?

Hi Jovo,

Could you please provide the following information so that we can give an accurate answer to your question?

1. An example of the flow you're trying to push (showing matches + actions)
2. The switch model and firmware you are using

When you enter the command "flow-location hardware-only" it will cause the switch to reject any flows which cannot be supported in the hardware table. The OFPT_ERROR message you're receiving below is sent because the flow you attempted to push cannot be supported in the hardware table.

Is there a specific reason that you are using OpenFlow 1.0 rather than OpenFlow 1.3?
