Router memory

HI,

This might be a stupid doubt..but though better i get it cleared rather than let it

bug me ..

The details of my Router memory as shown in the output of "she ver"

cisco 3660 (R527x) processor (revision 1.0) with 57344K/8192K bytes of memory

Details of the same router memory as shon in the output of "sh memory"

Head Total(b) Used(b) Free(b) Lowest(b) Largest(b)

Processor 6210F920 24053472 5469492 18583980 18352716 18540632

I/O 3800000 8388608 4300280 4088328 4051872 408809

My question is,

I believe that the router has 64 MB of memory, the Total processor memory is shown as 24 MB

and the IO memory is shown as 8 MB ..which adds up to a total of 32 MB. Where is the remianing

32 MB gone? or am i doing something wrong?

regards,

jimmy.

Hi Jimmy,

The show memory only gives you the total that is free after the IOS already allocated all it needs to run. So, basically, this only shows what's left.
