Openflow Instance; Protocols And Standards - H3C S12500-X Series Configuration Manual

OpenFlow instance

You can configure one or more OpenFlow instances on the same device. A controller considers each
OpenFlow instance as a separate OpenFlow switch and deploys forwarding instructions to it.
In this chapter, an OpenFlow switch is the same as an OpenFlow instance, unless otherwise specified.
Associated VLAN
When an OpenFlow instance is associated with VLANs, the flow tables take effect on packets only within
those VLANs.
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 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.
