Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software 
images support a specific set of features and which features are supported in a specific Cisco IOS image. 
You can search by feature or release. Under the release section, you can compare releases side by side 
to display both the features unique to each software release and the features in common. 

Cisco Feature Navigator is available 24 hours a day, 7 days a week, and is updated regularly when major 
Cisco IOS software releases and technology releases occur. For the most current information, go to the

The Cisco IOS Release 12.4 documentation set consists of the configuration guide and command 
reference pairs listed in 

 and the supporting documents listed in 

. The configuration 

guides and command references are organized by technology. For the configuration guides:

Some technology documentation, such as that for DHCP, contains features introduced in 
Releases 12.2T and 12.3T and, in some cases, Release 12.2S. To assist you in finding a particular 
feature, a roadmap document is provided.

Other technology documentation, such as that for OSPF, consists of a chapter and accompanying 
Release 12.2T and 12.3T feature documents.

In some cases, information contained in Release 12.2T and 12.3T feature documents augments or 
supersedes content in the accompanying documentation. Therefore it is important to review all 
feature documents for a particular technology.
