Datapath-Id - HP 5900 series Command Reference Manual

Parameters
multiple: Configures the controller mode as multiple for the OpenFlow instance to establish connections
to controllers.
single: Configures the controller mode as single for the OpenFlow instance to establish connections to
controllers.
Usage guidelines
An OpenFlow instance can connect to one or more controllers, depending on the controller mode the
OpenFlow instance uses:
Single—The OpenFlow instance connects to only one controller at a time. When communication
•
with the current controller fails, the OpenFlow instance uses another controller.
• Multiple—The OpenFlow instance can simultaneously connect to multiple controllers. When
communication with any controller fails, the OpenFlow instance attempts to reconnect to the
controller after a reconnection interval.

# Set the controller mode to single for OpenFlow instance 1.
<Sysname> system-view
[Sysname] openflow instance 1
[Sysname-of-inst-1] controller mode single
