Hi every body!
I have few question:
show version ( i omitted the output for brevity)
---------------
ROM: System Bootstrap, Version 5.2(8a), RELEASE SOFTWARE
BOOTLDR: 3000 Bootstrap Software (IGS-RXBOOT), Version 10.2(8a), RELEASE SOFTWAR
E (fc1)
1) To me it appears that"ROM: System Bootstrap, Version 5.2(8a), RELEASE SOFTWARE" show the bootstrap version if yes then what does"BOOTLDR: 3000 Bootstrap Software (IGS-RXBOOT), Version 10.2(8a), RELEASE SOFTWAR
E (fc1)" indicate ?
-----------------------------------------
"cisco 2500 (68030) processor (revision D) with 16384K/2048K bytes of memory"
1)The memory in above means RAM?
2) What does" 16384k/2048k" indicate?
----------------------------------------
show flash:
RouterA#show flash
System flash directory:
File Length Name/status
1 7923420 c2500-i-l.121-9.bin
[7923484 bytes used, 465124 available, 8388608 total]
8192K bytes of processor board System flash (Read ONLY)
The" 8388608" indicates the total flash size, but then what does " 8192k" indicate?
--------------------------------------
thanks a lot!

What does" 16384k/2048k" indicate?
This is your DRAM. Add both and your total DRAM should be around 18 Mb.

Thanks a lot Leolaohoo!
Now i understand memory in the output means dram and the total capacity of it is around 18MB( adding the 16384k/2048k0
But what does 16384 k/2048k indicate? My hunch is out of 18Mb, 2048k is available,the rest(16384k) is used.

It stands for:

The first value, Main Processor memory, is either:
â¢The amount of DRAM available for the processor, or
â¢The total amount of DRAM installed on the system.
The second value, Packet memory, is either:
â¢The total physical input/output (I/O) memory (or "Fast memory") installed on the router (Cisco 4000, 4500, 4700, and 7500 series), or
â¢The amount of "shared memory" used for packet buffering. In the shared memory scheme (Cisco 2500, 2600, 3600, and 7200 Series), a percentage of DRAM is used for packet buffering by the router's network interfaces.
Note The terms "I/O memory" or "iomem"; "shared memory"; "Fast memory" and "PCI memory" all refer to "Packet Memory". Packet memory is either separate physical RAM or shared DRAM.
