Usage guidelines
This command takes effect only on OpenFlow connections that the OpenFlow instance establishes
with controllers through TCP.
By default, an OpenFlow instance backs up OpenFlow connections established over TCP on the
subordinate device. This prevents connection interruption when a master/subordinate switchover
occurs.
Examples
# Disable OpenFlow connection backup for OpenFlow instance 1.
<Sysname> system-view
[Sysname] openflow instance 1
[Sysname-of-inst-1] controller tcp nsr disable

Default
The datapath ID of an OpenFlow instance contains the instance ID and the bridge MAC address of

of the device.
