7. On the OpenFlow switches in the controller domain, disable, then re-enable each controlled
OpenFlow instance. On ProVision OpenFlow switches use these commands in each OpenFlow
instance:
# openflow instance <instance-name> < enable | disable >
CAUTION: When the controller is restarted, it initializes controlled switches with a set of
rules that conform to the current hybrid mode setting. When changing the hybrid mode setting
and restarting the controller, the administrator should toggle each controlled OpenFlow instance
to force the related switch to re-initialize the tables it receives from the controller.
If this requirement is not followed, then the controller does not properly initialize controlled
switches, and unexpected network behavior may occur.
NOTE: You can also use the REST API to set or reset Hybrid mode. See the "configs REST
API" section in the HP VAN SDN Controller REST API Guide.
