HP VAN SDN Controller and Applications Support Matrix

• The default protocol version for OpenFlow instances for switches can vary. To use OpenFlow
1.3, you might need to configure the switch to set protocol version for the OpenFlow instance
to 1.3 or 1.3 only.
• Do not connect OpenFlow switches in a controller domain in a loop topology with switches
outside the domain. Allowing such connections can create broadcast loops inside the OpenFlow
network.
• OpenFlow switches in the network must be configured to allow control by the HP VAN SDN
Controller. In a controller domain, including a switch that does not support OpenFlow or allow
control by the HP VAN SDN Controller creates separate clusters of OpenFlow networks.
• The controller supports IPv4 addresses–but not IPv6 addresses–when communicating with
switches in the control pane.
• The following switch configurations are not supported for HP ProVision-based switches controlled
by the HP VAN SDN Controller:
◦ openflow ip-control-table-mode
◦ openflow instance instance-name flow-location hardware-only
◦ openflow egress-only-ports
◦ openflow instance instance-name software-flow-table {1-4}
• For HP ProVision-based switches running K/KA/WB.15.14.yyyy or earlier software versions,
HP recommends that you configure the switch to enable SNMPv2 with a public community
string (or configure a DeviceKey to match the switch’s community string) so that the controller
can identify the switch using SNMP. If the controller cannot identify the switch then Openflow
flow modifications sent to the switch might not achieve maximum efficiency.
• When configuring HP Comware-based switches, do not change the default flow-table
configuration, which is a single extensibility flow table (which has an ID of 0 (zero)).
