New Features in Cisco IOS XE Release 2.5

---

The following features were introduced in Cisco IOS XE Release 2.5. Links to feature documentation are also included.

Feature guides may contain information about more than one feature. To find information about a specific feature within a feature guide, see the Feature Information table at the end of the guide.

Feature guides document features that are supported on many different software releases and platforms. Your Cisco IOS software release or platform may not support all the features documented in a feature guide. See the Feature Information table at the end of the feature guide for information about which features in that guide are supported in your software release. 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.

For the latest feature information and caveats, see the release notes for your platform and software release: http://www.cisco.com/en/US/docs/ios/ios_xe/2/release/notes/rnasr21.html
