5. Restart the controller. In a controller team environment, restart all controllers in the team.
In a controller team environment, a configuration change on one controller typically propagates
to the other controllers on the team. However, to implement a hybrid mode configuration
change, it is necessary to restart all the controllers in the team. Make certain that the change
has propagated to all members in the team before restarting the controllers.
a. Close any instance of the web interface in which the controller might be running.
b. At the Linux command prompt (sudo), restart the controller with the following:
~$ sudo service sdnc restart
NOTE: You can also use the REST API to set or reset hybrid mode. See the "configs REST
API" section in the HPE VAN SDN Controller REST API Reference.

Coordinating controller hybrid mode and OpenFlow switch settings

Supporting hybrid mode on OpenFlow switches

The OpenFlow configuration on individual Hewlett Packard Enterprise switches must support
the controller hybrid mode setting.
hybrid mode configuration on the controller and the per-instance passive/active configuration on
Hewlett Packard Enterprise OpenFlow switches.

Hybrid Mode Settings
Enabled (true)
Disabled (false)
For more information on the specific switch, how to configure passive/active mode, and how
these switches behave if they lose their control-plane connection to the controller, see the
OpenFlow documentation.
For a list of switches that are supported in Hybrid and pure OpenFlow mode, see HPE VAN SDN
Controller and Applications Support Matrix.

Configuring controller settings to support hybrid mode

Network-related settings on the controller must agree with the controlled switches. Failure to
achieve agreement between the controller's network-related settings and the settings in the
controlled switches may result in unpredictable network behavior. Table
the specific network-related controller settings that should agree with managed switches.
For information on limitations in OpenFlow table support, see the HPE VAN SDN Controller and
Applications Support Matrix.

slower refresh rate will
respond more slowly to
a topology change.
