Cross-Platform Release Notes for Cisco IOS Release 12.2SB

---

September 30, 2008

Cisco IOS Release 12.2(33)SB2

OL-9967-03 Rev. E0

These release notes support Cisco IOS Release 12.2SB up to and including Cisco IOS Release 12.2(33)SB2. These release notes are updated as needed to describe new features, memory requirements, hardware support, software platform deferrals, and related documents.

Cisco IOS Release 12.2SB is tailored for service provider networks and large-scale enterprise networks. The main purposes of Release 12.2SB are the following:

•For the Cisco 10000 series, to introduce greater scalability for Multiprotocol Label Switching (MPLS) provider edge (PE) applications with the introduction of advanced High Availability (HA) capabilities.

•For the Cisco 7200 series, Cisco 7301, and Cisco 10000 series, to introduce the Intelligent Service Gateway (ISG).

•For the Cisco 7304, to introduce significant improvements for MPLS VPNs by supporting advanced quality of service (QoS) features such as a multiple action policer and support for 3-level hierarchical policies.

For more information, see the "Introduction" section.

For a list of the software caveats that apply to Cisco IOS Release 12.2SB, see the "Caveats" section, the Caveats for Cisco IOS Release 12.2 document, and the "Caveats" section in the Cross-Platform Release Notes for Cisco IOS Release 12.2S. These documents are updated for every maintenance release and are located on Cisco.com.

Use these release notes with the Cross-Platform Release Notes for Cisco IOS Release 12.2 document and the Cross-Platform Release Notes for Cisco IOS Release 12.2S, both of which are located on Cisco.com.

We recommend that you view the field notices for this release to see if your software or hardware platforms are affected.

Introduction

Cisco IOS Release 12.2SB is based on Cisco IOS Release 12.2(25)S and includes many features from Cisco IOS Release 12.2T.

For the Cisco 10000 series, Release 12.2SB supports select features from Release 12.2(25)S that include Multiprotocol Label Switching (MPLS) provider edge (PE) feature parity with Cisco IOS Release 12.0(27)S, along with greater scalability and feature enhancements.

For the Cisco 7200 series and Cisco 7301, all features that are in Release 12.2(25)S are also in Release 12.2SB. (Cisco IOS Release 12.2(33)SB does not support Cisco 7200 series and Cisco 7301 series routers. To upgrade, move to Cisco IOS Release 12.2(33)SRC.)

For the Cisco 7304, all features that are supported in Cisco IOS Release 12.2S, up to and including Release 12.2(25)S3, are also in Release 12.2SB.

Many of the features and the hardware that are supported in this software have been previously released to customers on other software releases.

For information on new features and Cisco IOS commands that are supported by Release 12.2SB, see the "New and Changed Information" section and the "Caveats" section.

Early Deployment Releases

These release notes describe the Cisco 7200 series routers, Cisco 7301 router, Cisco 7304 router, and Cisco 10000 series routers for Cisco IOS Release 12.2SB, which is an early deployment (ED) release based on Cisco IOS Release 12.2 and Release 12.2S. Early deployment releases contain fixes for software caveats and support for new Cisco hardware and software features. Table 1 shows the Cisco IOS Release 12.2SB early deployment releases for the above-mentioned platforms.

System Requirements

This section describes the system requirements for Cisco IOS Release 12.2SB and includes the following sections:

•Memory Recommendations

•Supported Hardware

•Determining the Software Version

•Upgrading to a New Software Release

•Microcode Software

•Feature Support

Memory Recommendations

---

Note Memory recommendations tables are not included in the Cisco IOS Release 12.2SB release notes to improve the usability of the release notes documentation. The memory recommendations will be available through Cisco Feature Navigator.

---

Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS and Catalyst OS 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 the Cisco Feature Navigator home page at the following URL:

http://www.cisco.com/go/fn

For frequently asked questions about Cisco Feature Navigator, see the FAQs at the following URL:

Determining Memory Recommendations for Software Images (Feature Sets)

To determine memory recommendations for software images (feature sets) in Cisco IOS Release 12.2SB, go to the Cisco Feature Navigator home page and perform the following steps.

---

Step 1 From the Cisco Feature Navigator home page, click Search by feature.

Step 2 To find the memory recommendations, 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 displayed in the Features available text box on the left side of the web page.

Step 3 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 web page.

---

Note To learn more about a feature in the list, click the Show Description(s) button below the Features available text box.

---

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

Step 4 Click Continue when you are finished selecting features.

Step 5 From the Major Release drop-down menu, choose 12.2SB.

Step 6 From the Release drop-down menu, choose the appropriate maintenance release.

Step 7 From the Platform drop-down menu, select the appropriate hardware platform. The "Search Results" table will list all the software images (feature sets) that support the feature(s) that you selected, plus the DRAM and flash memory recommendations for each image.

To upgrade, move to Cisco IOS Release 12.2(33)SRC. 3 Cisco IOS Release 12.2(31)SB4 is not publicly available. 4 Cisco IOS Release 12.2(31)SB and Release 12.2(31)SB1 are not publicly available.

Supported Port Adapters for the Cisco 7200 Series, Cisco 7301, and Cisco 7304

Table 3 lists the port adapters that are supported for the Cisco 7200 series routers, and Cisco 7301 router in Cisco IOS Release 12.2SB and uses the following conventions:

•Yes—The port adapter is supported in the software image.

•No—The port adapter is not supported in the software image.

•In—The release in the "In" column indicates the Cisco IOS 12.2SB release in which the port adapter was introduced. If a cell in this column contains an em dash (—), support for the port adapter was inherited from Cisco IOS Release 12.2 or from another release and was included in the initial base release of Cisco IOS Release 12.2SB.
