There are different fields on this form depending on whether one or both options are enabled. The form displays “Enable Data Buffering” and “Buffer to Syslog” options.
If “Enable Data Buffering” is active, the form displays different fields depending on whether “Local” or “Remote” are selected from the “Destination” menu.

If “Buffer to Syslog” is checked, data buffer files are sent to the syslog server.

The following table describes the fields available in the data buffering form.
circular or linear. In circular mode, data is written into the specified local data file until the upper limit on the file size is reached; then the data is overwritten starting from the top of the file as additional data comes in. Circular buffering requires the administrator to set up processes to examine the data during the timeframe before the data is overwritten by new data.
Note: The NFS server must already be configured with the mount point shared (exported), and the shared directory from the NFS server must be mounted on the ACS.
Choose a facility number to assign to ACS. Obtain the facility number for ACS from the system administrator of the syslog server. The facility number is included in any syslog message generated from ACS. The server’s administrator can use facility numbers to isolate logs from individual devices into individual files.
Buffer SysLog only when nobody is connected to the port
