This roadmap lists the features covered in this document and provides links to specific configuration information. To reach links to specific feature documentation and to see a list of the releases in which each feature is supported, see the following tables:

Table 1 lists features by the Cisco IOS Release in which they were introduced.

Table 2 lists features alphabetically by feature name.

Use Cisco Feature Navigator to find information about platform support and Cisco IOS and Catalyst OS software image support. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn. An account on Cisco.com is not required.

Not all commands may be available in your Cisco IOS software release. For release information about a specific command, see the command reference documentation.


Note Table 1 lists only the Cisco IOS software releases that introduced support for a given feature in a given Cisco IOS software release train. Unless noted otherwise, subsequent releases of that Cisco IOS software release train also support that feature.
