Hi Ahmed,


The first number is how much memory there is available for software, and the second number is how much memory there is available for I/O.  To get the megabyte, you add both numbers together and than divided by 1024.

917504K+65536K/1024=960.

So, you have approximately a gig of memory

Hi Ahmed,


yes you have to sum both values and get the total. DRAM is divided logically, combining the two numbers determines total DRAM.


Cisco <platform-processor-type> processor (revision <processor-revision-id>) with 
<free-DRAM-memory>K/<packet-memory>K bytes of memory.
