Periodic Maintenance Procedures
Step 1 Log in to a Cisco ITP-L, and enter the following Cisco IOS command to check the amount of available
memory:
show mem
The system returns a response like the following:
Head Total(b) Used(b) Free(b) Lowest(b) Largest(b)
Processor 80CF71E0 16813600 7885028 8928572 8900652 8891892
I/O 1D00000 19922944 6975904 12947040 12938256 12937500
Ensure that the memory used is less than 90 percent of the total available memory. If memory use is less
than 90 percent, the procedure is complete. If the response indicates that the Cisco ITP-L has a small
amount of available memory, you might need to add additional memory to the Cisco ITP-L to manage
call processing.
Note Be aware that the time of day when you enter this command will affect the overall accuracy of
the response. If you enter this command during your busiest hours, the amount of available
memory could be quite small. However, this memory reduction might not indicate a need to add
additional memory.
Consider performing this procedure during a period of less active call processing, to determine
an average amount of available memory.
Step 2 See the documentation for Cisco 2800 Series Integrated Services Routers for more information
pertaining to memory requirements.
Periodic Maintenance Procedures
This section contains procedures that are performed either automatically, on a schedule, by the system,
or that you perform regularly to maintain proper operation of the Cisco PGW 2200 Softswitch platform.
Schedule the procedures that you must perform manually according to your own requirements. The
maintenance procedures include the following:
• Automatic Disk Space Monitoring, page 3-24
• Automatic System Log Rotation, page 3-28
• Rotating System Logs Manually, page 3-28
• Creating a Disaster Recovery Plan, page 3-28
• Backing Up System Software, page 3-29
• Processing a Core Dump File, page 3-38
Note This section does not include information on maintaining the Sun host server hardware. You should
routinely perform general maintenance tasks and diagnostic checks on the host hardware. See the
documentation that Sun Microsystems (the hardware manufacture) provided, for detailed information on
such procedures.
