Activation and reactivation
The controller can deploy flow entries only to OpenFlow instances that are activated.
An activated OpenFlow instance need be reactivated when any of the following parameters are
changed:
• Associated VLANs
• Flow tables
• Maximum number of supported flow entries
After reactivation, the OpenFlow instance is disconnected from all controllers and reconnects to them.
OpenFlow instance port
An OpenFlow switch sends information about the following ports to the controller:
• Physical ports
• Logical ports
• Reserved ports of the local type
These ports belong to the VLANs that are associated with the OpenFlow instance only when all
associated VLANs are within the list of the VLANs to which the ports are assigned. However, if the loosen
mode is used, a port belongs to the OpenFlow instance when VLANs that are associated with the
OpenFlow instance overlap with the VLANs to which the port is assigned.
