LAGs When physical ports become LAG members, the flows installed by the OpenFlow Controller on these ports are removed from the hardware and the flows that are installed for the LAG are activated for the new LAG member port. The reverse action takes place when the ports are removed from the LAG. Ports The OpenFlow component installs flows in the hardware and removes flows from the hardware as ports become attached and detached or join and leave the LAG. When flows referencing a specific port in the match criteria or output actions are added to the hardware, the OpenFlow component operationally disables ingress filtering on the port. Ingress filtering is be re-enabled on those ports when flows are removed or aged-out. Network Interface ARP Table In some cases, the OpenFlow component may trigger ARP resolution for a specific IP address. Routing Interface ARP Table In some cases, the OpenFlow component may trigger ARP resolution for a specific IP address. QoS The QoS component does not interact with OpenFlow directly, but it shares the ingress field processor and VLAN field processor hardware resources with the OpenFlow component. The QoS component gracefully handles an out-of-resource condition and ensures that flows installed by the QoS component have precedence over the OpenFlow flows when the actions are in conflict. 1684 OpenFlow
