IOS 15: The dirty dozens
After four years, Cisco finally released a major overhaul of its operating system software, IOS. This was the next major upgrade to IOS 12.4, but in a turkey move the company couldn't bring itself to call it IOS 13, perhaps understandably. As for "14," well, who knows? Counting doesn't seem to be the router giant's strongpoint. Apparently, neither is simplicity. The day IOS 15 was released, Cisco admitted in its documentation that the new software had dozens of known bugs - or rather, "caveats." Better luck with the next release - which should be what, IOS 18?
