Cisco Announces EOS and EOL Cisco IOS Software Release 12.4

I noticed this today on the End of Life for IOS 12.4 being TODAY. As of today, most of your IOS 12.4 routers are running End of Life code and you should be preparing for an upgrade and End of Sale is in one year (that is, January 2011).

Points to Note

IOS 15 is the future

It would seem that Cisco wants you to upgrade to IOS 15 now, and not wait for years and years. Which gets me to thinking ….. does Cisco want us to take advantage of the new features ? Is IOS 15 an awesome new product ? Or is it the new licensing feature of the unified IOS image that will make more revenue ?

I’m sure that it’s all of those.

Either way Cisco isn’t waiting for us to find out. Off we go.

Standard five years

Software maintenance finishes in 2013. In other words, in two years there are no more bug fixes, you will be told to upgrade when there is a problem. Two years isn’t long
