Managing OpenFlow instances
SDNM provides multiple functions to manage OpenFlow instances, including viewing, querying, adding,
modifying, and deleting an OpenFlow instance. An OpenFlow instance is a virtual OpenFlow device.
The section is about viewing, querying, and deleting an OpenFlow instance. For more information about
adding and modifying a virtual OpenFlow device, see " Managing virtual OpenFlow devices ."
Viewing the OpenFlow instance list
OpenFlow instances in the OpenFlow instance list come from the following resources:
• Virtual OpenFlow devices that are synchronized from the controllers in SDNM.
• OpenFlow instances that are created by SDNM operators.
To view the OpenFlow instance list:
1. Click the Service tab.
