Hello,
this is normal on 36x0 and higher cisco boxes.
when you read :
cisco 3640 (R4700) processor (revision 0x00) with 24576K/8192K bytes of
memory.
this shows 32 MB of physical RAM present on the machine, but 24 MB used for
the software and 8MB used for the Input/Output Memory.
you can change the iomem by using the following command in config mode:
memory-size iomem x
where x specify the Physical memory percentage used as iomem. usually 20 to
25 % by default.
cheers

Then memory shown in my router by sh ver and show mem
are as follows.
===========================
WNPL36>>sh ver
WNPL3640>> uptime is 3 days, 19 hours, 10 minutes
System returned to ROM by power-on
System image file is "flash:c3640-i-mz.120-5.T1"
cisco 3640 (R4700) processor (revision 0x00) with 24576K/8192K bytes of
memory.
============================
and sh mem as
=============================
WNPL36>>sh mem
Head Total(b) Used(b) Free(b)
Lowest(b) Largest(b)
Processor 60C027E0 12572704 3245224 9327480 9167752 9239984
I/O 1800000 8388608 1890488 6498120 6477964
6498076
===================================
from sh mem total RAM including processor and I/O get nearly 20MB while
output of the command shows 32MB total RAM in my router.
Can anybody tell why this diffrence came in router.
Where that other RAM get utilize?
Thanks in advance
