Hierarchy Level


Store log files used for accounting data in the mfs/var/log directory (located on DRAM) instead of the cf/var/log directory (located on the compact flash drive). This feature is useful for minimizing read/write traffic on the router’s compact flash drive.


If log files for accounting data are stored on DRAM, these files are lost when you reboot the router. Therefore, you should back up these files periodically.
