I have 2 2501's here running enterprise + 12.1 with 8 flash and 16
dram
never crashes although it does takes an extra minute or two to boot up
because the image needs to be uncompressed

Hi,
Does anyone know how to compress IOS image. I have
2500 series router with 8mb flash and I want to load
enterprise software that is 15mb in size. I don't have
extra money to upgrade them to 16mb flash. If anyone
knows how pleae let me know asap, my lab date is next
week. Thanks
Mitch
Just remember that you are uncompressing the image into ram, and then
attempting to run it from there. If the image is 15MB in size, you can
most
likely compress it down to just under 8MB's. As soon as it loads though
it
most likely will crash the router, since max ram in a 2500 is 16MB and
you
have just taken up 15 of that. Even worse most 2500's set aside 2 MB's
as
buffer leaving 14MB to start with.
Believe me when I tell you, it will crash the router. I use images that
are
10MB requiring 6MB of Ram. When you start doing tricky stuff they some
times
start having MALLOC and TRACEBACK errors, or worse lock up tight.
11.3
enterprise is about as far as you can go doing this.
The same applies to TFTP'ing the image as well.
