Figure 44 Select the hybrid.mode Value field
In Figure 44 (page 74), the hybrid.mode field shows the current setting. Continue with the
following steps if you want to change the setting.
6. Set hybrid.mode to one of the following:
• true (the default): Enables hybrid mode. The controller makes packet-forwarding decisions
required by installed applications.
• false: Disables hybrid mode The controller makes all forwarding decisions. (Release 2.0
of the HP VAN SDN Controller operates only in this mode – pure OpenFlow mode. )
7. Restart the controller. In a controller team environment, restart all controllers in the team.
a. Close any instance of the web interface in which the controller may be running.
b. Using the command prompt at the root access on the Ubuntu system (sudo), restart the
controller with the following:
~$ sudo service sdnc restart
NOTE: In a controller team environment, a configuration change on one controller propagates
to the other controllers on the team. However, to implement a hybrid mode configuration
change, it is necessary to restart the controller. If the controller is operating in a team
environment, it is necessary to restart each controller in the team, as described above.
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
6.3 Coordinating controller hybrid mode and OpenFlow switch settings
6.3.1 Supporting hybrid mode on OpenFlow switches
The OpenFlow configuration on individual HP switches must support the controller hybrid mode
setting. Table Table 2 (page 74) shows the correspondence between the hybrid mode configuration
on the controller and the per-instance passive/active configuration on HP OpenFlow switches.
