For information about supported network switches, OpenFlow versions, and switch configuration requirements, see the HP VAN SDN Controller and Applications Support Matrix.
CAUTION: OpenFlow switches in a controller domain should not be connected in a loop topology with switches outside the domain. Allowing such connections can create broadcast loops inside the OpenFlow network. For more on packet-forwarding decisions, see “Hybrid mode for controlling packet-forwarding”. | |
The controller must be connected to a network that includes one or more switches configured to run OpenFlow. HP recommends that you plan and implement the switch OpenFlow configurations before connecting the controller to the network.
IPv6 traffic running in the data plane of an OpenFlow network is supported when the controller is operating with hybrid mode set to “true” (the default). In this state the controller is not aware of the IPv6 traffic. However, with hybrid mode set to “false” (all packets sent to the controller), the controller drops IPv6 packets, and they do not reach their destinations. For more information, see the release notes.
