You can configure the wireless controller to generate Call Detail Records (CDRs), which contain usage information about each wireless session per VNS. For more information on how to configure the controller to generate CDRs, refer to Defining Accounting Methods for a WLAN Service.
CDRs are located in a CDR directory on the controller. To access the CDR file, you must first back up the file on the local drive, and then upload it to a remote server. After the CDR file is uploaded to a remote server, you can work with the file to view CDRs or import the records to a reporting tool.
You can back up and upload the file on the remote server either via the Wireless Assistant (GUI) or CLI.
