Usage
Information
You must configure a controller for the logical switch instance. The logical switch instance is disabled
by default. To establish a connection with the controller, enable the logical switch instance using the
no shutdown command. All physical and logical interfaces in the switch are assigned to the configured
logical switch.
The no form of this command removes the logical switch instance.
NOTE: OS10 supports only one instance of the logical switch. If you attempt to create a second
logical switch instance, the following message appears:
% Warning: Only one Switch instance is supported
Example
OS10# config terminal
OS10 (config)# openflow
OS10 (config-openflow)# switch of-switch-1
OS10 (config-openflow-switch)# no shutdown
