Mainline: Feature Guides

Cisco IOS software is packaged in feature sets that are supported on specific platforms. To get updated 
information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature 
Navigator dynamically updates the list of supported platforms as new platform support is added for the 
feature.

Cisco Feature Navigator is a web-based tool that enables you to quickly 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. 

To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or 
lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check

details with a new random password will be e-mailed to you. Qualified users can establish an account

The Cisco IOS software documentation set consists of the Cisco IOS configuration guides, Cisco IOS 
command references, and several other supporting documents. The Cisco IOS software documentation 
set is shipped with your order in electronic form on the Documentation CD-ROM, unless you 
specifically ordered the printed versions.

Each module in the Cisco IOS documentation set consists of one or more configuration guides and one 
or more corresponding command references. Chapters in a configuration guide describe protocols, 
configuration tasks, and Cisco IOS software functionality, and contain comprehensive configuration 
examples. Chapters in a command reference provide complete command syntax information. Use each 
configuration guide with its corresponding command reference.
