White Paper Abstract:
The purpose of this document is to help service providers that might be affected by the behavioral changes to migrate from Release 12.2T to Release 12.2S. Enterprise customers will be affected when these changes are ported to future T train release. Customers migrating to releases 12.0 (26)S and later will not be affected, because the QoS functionality support was introduced in this release.
This document is not intended to discuss all of the new MQC feature capabilities that have been introduced on the Cisco 7200 Series Router and other lower-end hardware. For a complete list of new feature capabilities, please refer to the appropriate Cisco IOS Software release documentation on Cisco.com.
