Hi,
i have a Question to Router RAM usage.
My Router have 512MB of Memory.
When i do a "show version" I get this otput:
Cisco ********* processor with 491520K/32768K bytes of memory.
This means 491MB for CPU and 32MB for IO.
Now i do a "show memory" and get this output:
Head Total(b) Used(b) Free(b) Lowest(b) Largest(b)
Processor 6353EB60 430707644 14276428 416431216 416363448 413930428
I/O E000000 33554432 1884520 31669912 31669912 31669884
Now here are only 430MB Total RAM for the Processor. Why this? What is with the other 60MB Memory? How does these values are in context with the Output of a "show region"?
Region Manager:
Start End Size(b) Class Media Name

Thank in advance
