Re: permission error

I see that you're sending packets out of multiple ports on VID 1. Is this VID a member of the OpenFlow instance you're sending PACKET-OUT messages to?

If you could post the switch configuration and firmware version, it would be helpful in diagnosing this behavior.

Re: permission error

thanks for response this problem seem to happen because openflow was configured in aggregate mode its okay when i configure using a member vlan

Re: permission error

Thanks for the follow-up, although the functionality should work in either mode. Essentially an aggregate instance is just a vlan-based instance with all vlans (except the control-plane) in the instance. I wonder the aggregate instance was configured with VLAN 1 as the control-plane?
