can anyone explain why i could be getting a permission error. could it be because of LLDP i am doing an experiment and i am using LLDP packet to calculate delay. but it wont work. here is the debug output below.

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.

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

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?
