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.
