How to Commission the Cisco AS5850 Universal Gateway

Step 4 Inspect the boot flash.

AS5850# dir bootflash:

Directory of bootflash:/

1 -rw- 1863976 Mar 01 1993 00:05:28 c5850-boot-mz.May26

15990784 bytes total (14100676 bytes free)

Note Keep a backup copy of the RSC Cisco IOS image in boot flash in case compact-flash memory

cards are misplaced.

Step 5 Inspect the NVRAM memory on the RSC. Three files are present:

• The initial boot or startup-config.

• The private-config. This is a secure file that supports encryption technologies. It is not user

accessible.

• The underlying-config. This is the version of the startup-config that is stored in NVRAM.

AS5850# dir nvram:

Directory of nvram:/

1 -rw- 739 <no date> startup-config

2 ---- 24 <no date> private-config

3 -rw- 739 <no date> underlying-config

129016 bytes total (128277 bytes free)

Verify Memory Usage

Use the show memory summary command to do the following:

• Verify how memory is used for different processor and I/O memory processes.

• Identify memory leaks or fragmentation.

–

Memory leaks occur when memory is not released back to the processor. They are indicated by

steady decreases of free memory. However, the preferred way to track memory leaks is to

monitor the FreeMem variable in the OID MIB.

–

Memory fragmentation is indicated when the largest block of memory is unequal to the free

block. Fragmentation increases as the numbers grow further apart.

To determine and calculate memory usage, perform the following steps.

Step 1 Display the memory status report. In the example, the largest memory block is close to the free-memory

block. There is no fragmentation.
