OpenFlow 1691
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.
