HP VAN SDN Controller and Applications Support Matrix

1.3 IPv4 address requirements
The HP VAN SDN Controller and the devices with which it communicates must use IPv4 addresses
on the control plane. The controller does not recognize devices that use only IPv6 addresses on
the control plane.
IPv6 traffic running in the data plane of an OpenFlow-hybrid network can be supported. For more
information about supporting IPv6 traffic on the data plane, see the HP VAN SDN Controller
Release Notes.
1.4 Supported OpenFlow versions
The controller:
• Supports multiple OpenFlow versions at the same time.
• Negotiates with each OpenFlow switch for the highest common OpenFlow version between
the switch and controller.
After the OpenFlow version is identified for a switch, the controller continues to operate using
that version as long as the switch is connected to the controller. Rebooting the switch—such
as for a software update—breaks the connection and results in a new negotiation between
the switch and the controller for the highest common OpenFlow version.
NOTE: The default protocol version for an OpenFlow instance on a switch might not be the
highest OpenFlow version. You might need to change the configuration of OpenFlow instances
on the switch to ensure that the controller and switch negotiate to use the OpenFlow version
that you want them to use.

HP VAN SDN Controller 2.2
and later versions
• OpenFlow 1.3.1
• OpenFlow 1.0.1
1.5 Use of SNMPv2 by the controller
The controller uses SNMPv2 to access MIB (Management Information Base) objects to collect
information from OpenFlow-enabled switches.
1.6 Supported network switches
The controller supports different switches depending on whether the network is an OpenFlow-only
network with the controller hybrid.mode set to false, or an OpenFlow-hybrid network with the
controller hybrid.mode set to true.
For more information about HP OpenFlow-enabled switches, see:
www.hp.com/networking/openflow
For more information about hybrid.mode, see the HP VAN SDN Controller Administrator Guide.
1.6.1 Configuration Requirements for switches used with the HP VAN SDN Controller
• Only the switches and software combinations that are explicitly listed are supported for the
controller or application.
• Unless otherwise indicated, switch and software combinations that support OpenFlow 1.3
also support OpenFlow 1.0. Using OpenFlow 1.3 instead of OpenFlow 1.0 can benefit
performance.
