Upgrading to a New Software Release
For general information about upgrading to a new software release, see Software Installation and
Upgrade Procedures located at: http://www.cisco.com/warp/public/130/upgrade_index.shtml.
Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the
platform. Each feature set contains a specific set of Cisco IOS features. Release 12.2(8)YL1 supports
the same feature sets as Releases 12.2 and 12.2(8)T, but Release 12.2(8)YL1 includes new features
supported by the Cisco 1700 series routers.
Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data
encryption feature sets) are subject to United States 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 can be denied or subject to delay due
to United States 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 [e-mail].
Table 2 through Table 6 list the features and feature sets supported in Cisco IOS Release 12.2(8)YL1:
• Table 2—Cisco 1710 routers
• Table 3—Cisco 1720, 1721, 1750, 1751, and 1760 routers
• Table 4—Cisco 1721, 1751, and 1760 routers
• Table 5—Cisco 1750, 1751, and 1760 routers
• Table 6—Cisco 1751 and 1760 routers
The tables use the following conventions:
• Yes—The feature is supported in the software image.
• No—The feature is not supported in the software image.
• In—The number in the “In” column indicates the Cisco IOS release in which the feature was
introduced. For example, “12.2(8)YL” means the feature was introduced in 12.2(8)YL. If a cell in
this column is empty, the feature was included in a previous release or the initial base release.
Note These feature set tables only contain a selected list of features, which are cumulative for
Release 12.2(8)nn early deployment releases only (nn identifies each early deployment release). The
tables do not list all features in each image—additional features are listed in the Cross-Platform
Release Notes for Cisco IOS Release 12.2 T and Release 12.2 T Cisco IOS documentation.
