Cisco Announces Extended Support for Cisco IOS Software

Release

12.4(15)T

PB496283

Updated: June 2009

Details

Cisco IOS Software Release 12.4(15)T will receive extended bug fix support until January 2012.

In addition, Release 12.4(15)T8 (scheduled for release in the December 2008 timeframe) and subsequent rebuilds

of Release 12.4(15)T will receive a Maintenance Deployment (MD) release designator. MD defines Cisco IOS

Software releases providing bug fix support and ongoing software maintenance.

Cisco is taking this action to indicate that Release 12.4(15)T8 and subsequent Release 12.4(15)T maintenance

rebuilds will be treated in a similar manner as Release 12.4 Mainline. Both undergo comprehensive testing and

review cycles to continuously improve and increase reliability, quality, and stability. As per Cisco policies, no new

technologies or features are added to either Release 12.4 Mainline or maintenance rebuilds of Release 12.4(15)T.

Release 12.4(15)T provides significant software feature benefits and hardware support over Release 12.4 Mainline.
