Thank very much you for those precisions! this what I get with sh flash :
#sh flash > > System flash directory: > File Length Name/status > 1 4305884 c2500-i-l.112-18 > [4305948 bytes used, 4082660 available, 8388608 total] > 8192K bytes of processor board System flash (Read ONLY) > I conclude is that it is worst testing to put a new IOS and try as it seems that I don't need a memory upgrade to run the IOS 11.2(26g) ... The traffic is for an office with approx. 20 machines: http mainly ... I already have a tftp server somewhere on my network (used previously for a net install of debian with pxe) which should help i guess for the upgrade ... Now how can I get this image ? Can someone help me on this ? I came accross this one : IOSHunter but after reading this<http://spod.cx/blog/ioshunter_lies.shtml>I'm reluctant to use it :-( Don't understand why IOS image are so hard to get... cordially, 2007/11/16, Mark Tinka <[EMAIL PROTECTED]>: > > On Friday 16 November 2007 15:11, Ben wrote: > > > currently running IOS version 11.0. > > The fact is that I wanted to do NAT with it but it seems > > that the first image of IOS able to do NAT is the 12.0. > > Not quite. > > The oldest image that supports NAT on the 2500 Cisco series > routers is IOS 11.2. > > > I have 3 questions for you guys : > > Pb 0 : Is it worst working on a old box like this ? > > Depends on the amount of traffic you are looking to push. > The 2500 is an old box, and NAT is both CPU and memory > intensive. > > > Pb 1 : How do I know if my particular router can support > > the IOS 12.0version and how can I get the right image ? > > You need to have a CCO account with Cisco or ask the mailing > lists, like you've just done. > > > Pb 2 : If not, does a memory upgrade can help ?
