177 Chapter 25 Session Trace
25.1.2 Session Trace Filename Convention
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.
Figure 117 Session Trace Information Example
The following table describes the fields in a session information file.
TFTP Server IP
Address
Specify the primary and/or secondary TFTP IP address in the Primary TFTP Server
IP Address and/or Secondary TFTP IP Address fields.
Enter the IP address(es) in dotted decimal notation. For example, 192.168.1.10.
Enter the time interval (in minutes between 5 and 1440) the VSG waits before
sending the session information to the TFTP server(s).
Note: If there are 50 session trace records, the VSG sends the
session information to the TFTP server even if the time interval
is not up.
