Core Issue
To import switch port configurations, Cisco Emergency Responder (Cisco ER) must already be configured with the switch and Cisco ER must first discover the ports on the switch using the switch-port and phone update process. When attempting to import a configuration for ports not yet discovered in Cisco ER, importing those settings fails.
Resolution
Run the switch-port and phone update process on the switches whose port configurations cannot be imported, then retry the import. For information on how to perform the procedure, refer to the Manually Running the Switch-Port and Phone Update Process section of Configuring Emergency Responder.
