To choose a new Cisco IOS software release by comparing feature support or memory requirements, useCisco Feature Navigator. Cisco Feature Navigator is a web-based tool that enables you to determine whichCisco IOS software images support a specific set of features and which features are supported in a specificCisco IOS image. You can search by feature or by feature set (software image). Under the release section,you can compare Cisco IOS software releases side by side to display both the features unique to each softwarerelease and the features that the releases have in common.
To choose a new Cisco IOS software release based on information about defects that affect that software, useBug Toolkit at the following URL: http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl.

Feature SupportCisco IOS software is packaged in feature sets that consist of software images that support specific platforms.The feature sets available for a specific platform depend on which Cisco IOS software images are includedin a release. Each feature set contains specific Cisco IOS features.
Cisco IOS images with strong encryption (including, but not limited to 168-bit [3DES] data encryption featuresets) are subject to U.S. government export controls and have limited distribution. Strong encryption imagesto be installed outside the United States are likely to require an export license. Customer orders may be deniedor subject to delay because of U.S. government regulations. When applicable, the purchaser/user must obtainlocal import and use authorizations for all encryption strengths. Please contact your sales representative ordistributor for more information, or send an e-mail to [email protected].
Caution
