The subscriber session information is stored a plain text file with a “txt” filename extension. The general structure of the filename is <hostname>DDMMYYHHMMSS.txt. For example, “MIS221004131543.txt” is the file name of a session information file created at 13:15:43 PM on October 22, 2004 on a VSG with a hostname of “MIS”.
You can view the subscriber session trace information using any text editor. The following figure shows an example of the session information file the VSG sends to a TFTP server.
