To choose a new Cisco IOS software release by comparing feature support or memory requirements, use 
Cisco Feature Navigator. 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 by feature set (software image). Under the 
release section, you can compare Cisco IOS software releases side by side to display both the features

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology 
releases occur. For the most current information, go to the Cisco Feature Navigator home page at the
