End-of-Life for Cisco IOS Release 11.3 / 11.3AA / 11.3T

Cisco IOS Release 11.3 and 11.3T reached their End of Sales [EoS] and End of Engineering [EoE] date on Aug. 2, 1999.

Product Bulletin No. 847

As defined in the End of Life policy, 11.3 and 11.3T reached their End of Life date 5 years after the EoS date, on August 2, 2004.
This means that support is no longer provided for Cisco IOS Release 11.3 and 11.3T.
For continued support, customers should upgrade to, at least, Release 12.0.
The current Cisco IOS Software releases, as of January 2005, are 12.3(x) [mainline], 12.3(14)T [early technology deployment], and 12.2(x)S /12.2(x)SX [high-end routing].

End of Product Life Cycle ("End of Life" or "EoL") -- A process that guides the final business operations associated with the product life cycle.

The end-of-life process consists of a series of technical and business milestones and activities that, once completed, make a product obsolete. Once obsolete, the product is not sold, manufactured, improved, repaired, maintained, or supported. In other words, the release has reached the "you're SoL" point (when it comes to tech support for that release you bought in 1998).

Though, historically, we have recommended that customers use the lowest supported release number if they wanted the greatest "stability". Or at least we used to. New security features have changed that recommendation though. Also, there's a whole colony of Cisco-Borg fixing bugs all the time, so you don't want to miss out on that, now, do you?


Cisco IOS Release 12.3T

The 6th (and final) public release of the early technology deployment IOS Software train 12.3T is 12.3(14)T.
It had a target release of Feb. 28, 2005, and was actually released March 28, 2005. The 12.4 mainline release follows 30 days after that.

Cisco IOS Release 12.4

Released as of June 2005.

Features in Release X are designed to meets the specific needs of Market Y

12.2S "family" of releases .................................. "EDGE" and "ENTERPRISE"*


* Enterprise does not mean "starship": it means very large corporation (a big "business" with lots of employees)


Platforms are the end-user products that receive TL 9000 registration.
ITD must be fully compliant with TL 9000 requirements because IOS is a major component of the platforms.
ITD’s primary focus is on the 12.2S releases for c6K, 7600 and c10K platforms. (Service Provider)
ITD must also support 12.0S for c12K
