I passed my CCNA back in '02 (as well as Routing and Switching towards the NP), but then was sidetracked into Windows/Exchange ever since. Finally back to the network side of the fence.
I need to redo my NA, then head for the NP, so I dusted off the kit I bought back in '02... three 2500's and a Cat 1924. I know, all EOL, but I figure still good enough to work with, considering what I also have on the job to play with.
Finally, the question... the 2500's are running something like 12.1(19) (not 100%... they're at home and I'm not). The IOS page volunteers nothing (if it does, it's darn cryptic) regarding last viable IOS version for the 2500. Anyone running anything stable in the 12.2 and beyond range?
