Determining the Software Release

To determine which release of Cisco IOS software is currently running on your Cisco routers, log in, and enter the show version command. The following sample output indicates the release number on the second output line for the Cisco 1800 series fixed routers.

Router> show version 
Cisco IOS Software, C1800 Software (C1800-ADVENTERPRISEK9-M), Version 12.4(11)XW, EARLY 
DEPLOYMENT RELEASE SOFTWARE

Upgrading to a New Software Release

For general information about upgrading to a new software release, see the Software Installation and Upgrade Procedures located at http://www.cisco.com/en/US/products/hw/routers/ps259/products_tech_note09186a00801fc986.shtml

Feature Set Tables

Cisco 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 included in a release. Each feature set contains a specific set of Cisco IOS features.

---

Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to U.S. government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of U.S. government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

---

Feature set tables were removed beginning with the Cisco IOS Release 12.4 release notes because feature-to-image mapping that was provided by the feature set tables is available through 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 unique to each software release and the features that the releases have in common.

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to http://www.cisco.com/go/cfn.

Determining Which Software Images (Feature Sets) Support a Specific Feature

To determine which software images (feature sets) in your Cisco IOS release support a specific feature, from the Cisco Feature Navigator home page perform the following steps.

---

Step 1 Click Search by feature.

Step 2 To find a feature, use either "Search by full or partial feature name" or "Browse features in alphabetical order." Either a list of features that match the search criteria or a list of features that begin with the number or letter selected from the ordered list will be visible in the Features available text box on the left side of the page.

Select a feature from the Features available text box, and click the Add button to add a feature to the Features selected text box on the right side of the page. Repeat this step to add additional features. A maximum of 20 features can be chosen for a single search.

---

Note To learn more about a feature in the list, click the button below the Features available text box.

---

Step 3 Click Continue when you finish selecting features.

Step 4 From the Major Release drop-down menu, choose your release.

Step 5 From the Release drop-down menu, choose the appropriate maintenance release.

Step 6 From the Platform drop-down menu, select the appropriate hardware platform. The "Search Results" table lists all the software images (feature sets) that support the feature(s) that you selected.

---

Determining Which Features Are Supported in a Specific Software Image (Feature Set)

To determine which features are supported in a specific software image (feature set) in your Cisco IOS release, go to the Cisco Feature Navigator home page and perform the following steps.

---

Step 1 From the Cisco Feature Navigator home page, click Compare Images, and then Search by Release.

Step 2 In the "Find the features in a specific Cisco IOS release, using one of the following methods:" area, choose your release from the Cisco IOS Major Release drop-down menu.

Step 3 Click Continue.

Step 4 From the Release drop-down menu, choose the appropriate maintenance release.

Step 5 From the Platform drop-down menu, choose the appropriate hardware platform.

Step 6 From the Feature Set drop-down menu, choose the appropriate feature set. The "Search Results" table lists all the features that are supported by the feature set (software image) that you selected.

New Features

For information regarding the features supported in your Cisco IOS release, see the Cisco IOS cross-platform release notes for your Cisco IOS release.

Caveats

Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels. See the caveats documentation for your Cisco IOS release.

---

Note If you have an account on Cisco.com, you can also use the Bug Toolkit to find select caveats of any severity. To reach the Bug Toolkit, log in to Cisco.com and go to: http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl.  (If the defect that you have requested cannot be displayed, this may be because one or more of the following reasons: the defect number does not exist, the defect does not have a customer-visible description yet, or the defect has been marked Cisco Confidential.)
