Parameters
multiple
: Specifies the

Usage guidelines
In
single
mode, the OpenFlow switch connects to only one controller at a time. When
communication with the current controller fails, the OpenFlow instance uses another controller.
In
multiple
mode, the OpenFlow switch simultaneously connects to all controllers. If one or more
controllers become invalid or disconnected, the OpenFlow switch continues to exchange messages
with the rest of the controllers.

# Set all controllers of OpenFlow instance 1 to operate in
single
mode.

[Sysname] openflow instance 1
[Sysname-of-inst-1] controller mode single
