Listen port or controller error

Commands issued from listen port or controllers are not successful.

1. Enable debug openflow which will display the switch output helping you to identify whether

the error is occuring at the switch or the controller.

2. Enable debug openflow instance [instance-name] to further identify the error.

3. Verify the packet capture for the request and reply to isolate whether the error is occuring at

the switch or the controller.

NOTE: This problem occurs if some controllers do not fully conform to the specification and

therefore cannot handle replies from the switch. The replies in the packet capture will be visible

from the switch but not from the controller.

4. Enable debug destination session to further identify the error.

Specifying a port

If you are trying to specify an application port that is out of range will result in an error message
