Re: Router IOS enquiry

Hi,

This answer your question

Q. What is the relationship between major releases and new technology releases?

A. Technology releases (ie: Release 12.3T) are those Cisco IOS Software releases that introduce new features, functionality, and hardware support. A major release (ie: Release 12.4) consolidates features/functions previously introduced in technology releases. A major release emphasizes stability and reliability.

Release 12.4 is a major release. Major releases consolidate features/functions previously introduced in technology releases. A major release emphasizes stability and reliability. No features or functions are added after First Commercial Shipment (FCS). Major releases, matured through maintenance releases, are designed for areas of the network carrying business-critical applications.
