show version output on router

[sarahr202]

Hi every body!

I have few questions about the output of " show version" command.

Show version command displays a lot of information.

I am interested in following :

The " show version " command gives info about:

Ram

nvram

flash

For ram, 354304k/38912k, book says the sum of these two gives the total amount available. Is the total size of ram or free ram available?

For nvram 191k bytes nvram? is the total size of nvram or available memory in nvram ?

For flash, 125440k bytes of ATA copact flash, is it total size or free memory available in flash ?

Thanks and have a nice weekend!

for Ram, nvram, and flash the output in show version gives the total amount of memory of the various types. There are ways to find available memory for Ram and flash, but not from the show version command.

Hi Rick.

Thanks for your reply.

"There are ways to find available memory for Ram and flash, but not from the show version command".

Could you please elaborate on those methods ?

Thanks a lot.

To find out how much available flash, you can use dir or show flash:. Here is an example:

R1#dir

Directory of flash:/

1 -rw- 53139536 Jun 26 2009 18:52:30 +00:00 c2800nm-adventerprisek9-mz.124-15.T9.bin

256471040 bytes total (203329536 bytes free)

To find out how much available, you can use the show memory command. Here is an example:

R1#sh mem

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

Processor 46C2C990 142423664 22430288 119993376 118026688 118846512

HTH,
