Activation and reactivation
The controller can deploy flow entries only to activated OpenFlow instances.
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 then reconnected 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. To prevent errors,
make sure all associated VLANs are within the list of the VLANs to which the ports are assigned.
