Chapter 21 Syslog and Session Trace

167

You can set the VSG to send session information of subscribers accessing the Internet. The 
VSG records the session information and stores it temporary. Once the session trace 
information reaches a maximum of 50 records or the specified time period is reached, the VSG 
sends the session information to the specified TFTP server. 

To configure the VSG to send subscriber session information, click Advanced, Session Trace 
to display the screen as shown.
