Custom Application Detectors
If you use a custom application on your network, you can create a custom web application, client, or application protocol detector that provides the system with the information it needs to identify the application. The type of application detector is determined by your selections in the Protocol, Type, and Direction fields.
Client sessions must include a responder packet from the server for the system to begin detecting and identifying application protocols in server traffic. Note that, for UDP traffic, the system designates the source of the responder packet as the server.
If you have already created a detector on another management center, you can export it and then import it onto this management center. You can then edit the imported detector to suit your needs. You can export and import custom detectors as well as detectors provided by Cisco Professional Services. However, you cannot export or import any other type of Cisco-provided detectors.
