Introduction

These release notes include important information about the Cisco IOS Release 15.4(3)S that runs on the Cisco 7600 Series Routers. Use this document in conjunction with the previous Cross-Platform Release Notes for Cisco IOS Release 15.4S.

These release notes also include the limitations, restrictions, and caveats that apply to these releases.

You can verify that these release notes apply to your switch as follows:

• If you are installing a new switch, see the Cisco IOS release label on the rear panel of your switch.
• If your switch is on, use the show version privileged EXEC command. See the Determining the Software Version section.

For the complete list of Cisco 7600 Series Routers documentation, see the Related Documentation section.

System Requirements

This document describes the system requirements for Cisco IOS 15.4S releases and includes the following sections:

• Feature Support
• Memory Recommendations
• Hardware Supported
• Determining the Software Version
• Upgrading to a New Software Release

Feature Support

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 specific 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. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

---

Feature-to-image mapping 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). 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 the Cisco Feature Navigator home page at the following URL:

www.cisco.com/go/cfn

For help with Cisco Feature Navigator, see the help information at the following URL:

---

Repeat this step to add features. A maximum of 20 features can be chosen for a single search.

Step 5 Click Continue when you are finished choosing features.

Step 6 In the Release/Platform Tree area, select either your release (from the Train-Release list) or your platform (from the Platform list).

Step 7 The “Search Result” table will list all the software images (feature sets) that support the features that you chose.

---

Note You can download your results into an Excel spreadsheet by clicking on the Download Excel button.
