HP VAN SDN Controller Release Notes

• Connected Links disappear between the OpenFlow switches when spanning tree is enabled
(CR140755)—When enabling spanning tree in OpenFlow switches, controller-sent LLDP
packets are not being forwarded from STP_BLOCKED ports, causing the discovered links to
be deleted and link rediscovery to not occur on the ports.
• Openflow 1.3 badly formed MultipartReply/FLOW stats message (CR142663)
—java.lang.IllegalStateException: “Timed-out waiting for response” might appear when the
REST API is invoked to list all flows on a datapath from the SDN Controller. This occurs due
to the information sent from the switch firmware.
• When RESTAPi /stats/ports/ is executed with dpid & portid filter, an exception is thrown with
response code 500 (CR142114) —HTTP/1.1 500 Internal Server Error might appear when
the REST API is invoked to get stats for a port (GET /stats/ports) in a datapath from the SDN
Controller. This appears due to the incorrect information from the Openflow devices (Switch
CR 131910:dpctl stats-port <port> command displays empty stats.)
• The RESTAPi /datapaths/{dpid}/ports/{port_id}/action fails to change the state of the port
(CR140753)—The port state does not get changed when the REST API is invoked to change
the state of a port in a datapath from the SDN Controller due to the design in the Provision
switches.
