Updated Cisco IOS Software Documentation

Starting with Cisco IOS Release 12.2SRC, the Cisco IOS 12.2SR documentation set includes a suite of configuration guides as companions to the command references. The configuration guides document Cisco IOS software features supported in Cisco IOS release 12.2SR. Feature descriptions may contain configuration information that applies to other releases if that feature is supported in multiple releases or on many platforms.

The Cisco IOS command references continue to include documentation of commands supported (for example, in Cisco IOS Release 12.2SR), but also include commands supported in other major releases, such as Cisco IOS Release 12.2SX. As a result, some commands found in these books may not be supported in the Cisco IOS Release 12.2SR release.

Check out these recently updated configuration guide s and command references today:

• 12.2SR Configuration Guides
• 12.2SR Command References
• 12.2SX Command References
• 12.2SB Command References
• 12.4T Command References
• 12.4 Command References
