Configuring OpenFlow instances
Configuration restrictions and guidelines
When you configure OpenFlow instances, follow these restrictions and guidelines:
•
The switch supports up to 128 route entries. When you deploy more than 128 route entries to the
switch through controllers, use the display ip routing-table command to view the effective route
entries.
•
Delete the flow entries deployed to a port before removing the port from the group table or the
VLANs that are associated with an OpenFlow instance. Removing a port from the group table or the
VLANs that are associated with an OpenFlow instance does not automatically delete the flow
entries deployed to the port by controllers.
•
When you delete a VLAN interface that is associated with MAC-IP flow entries, create a new VLAN
interface for controllers to deploy new flow entries.
•
A forwarding conflict might occur when you configure the same service through both the controller
and CLI. To ensure the correct forwarding, configure a service either by deploying flow entries
through the controller or using CLI.

By default, an OpenFlow instance
does not have a description.
Associating an OpenFlow instance with VLANs
When you associate an OpenFlow instance with VLANs, follow these guidelines:
•
Do not associate multiple OpenFlow instances to the same VLAN. Otherwise, VLAN traffic cannot
be correctly processed.
•
When you activate an OpenFlow instance that is associated with non-existent VLANs, the system
automatically creates the VLANs. Do not delete any of these VLANs after the OpenFlow instance is
activated.
•
VLANs that are associated with an OpenFlow instance cannot contain loopback interfaces.
