Hi,
Had a question on the output of a sh ver. command on my 2501 router.
The memory reads 2048/2048 bytes of memory. The NVRam has 32K of memory and
the system flash reads 8192K bytes of processor board System flash.
Why does the memory read 2048/2048? Does this mean it had 4MB of total RAM
but what is the significance of the (/)slash?
Since the startup-config file resides in NVRam, and only the startup file is
in NVRam, is it why it has only 32K of memory? Would I ever need to upgrade
this?
Regarding flash, does it have it's own 8Mb of memory? Since this is needed
to load the IOS, will this also ever have to be upgraded depending on the
ver. of IOS being used?
Also the sh ver. command shows Bridging software and X.25 software ver.
3.0.0? What is this software and what does it do?
None of the books that I have read explain basic things like this that I
feel is very important to understand the basics of a router - just like
understanding the internal components of a pc. Most books go straight into
configuring routers etc.
Please advise.
Thank you.
Kind regards,
