Question regarding Show Version Field 1

[AndrewAllen]

In show version, there is the following field that describes installed memory:

cisco 2610 (MPC860) processor (revision 0x202) with 53248K/12288K bytes of memory.


What are the "numerator" and "denominator" values listed? In this case they add up to 64MB, which is what is installed. But why the distinction between the two values?

Thanks,

Andy.

From your example:

cisco 2610 (MPC860) processor (revision 0x202) with 53248K/12288K bytes of memory.

53248K = Primary Memory
12288K = Shared Memory

And from Cisco's site:
Primary memory is used to store the operating configuration, routing tables, caches, and queues. Shared memory is used to store incoming and outgoing packets. In the table below, the physical configuration column lists the amount of DRAM SIMM memory supported.

So - the show version output simply shows how the memory is being allocated between router functions.

Good day!
