Cisco Express Forwarding Enhancements: Removal of IP Fast Switching and Introduction of CLI Changes

The purpose of this document is to describe the changes based on the Cisco Express Forwarding infrastructure scalability enhancements implemented to adapt to the evolution of the Internet and to support new platforms and features. The changes are the removal of IP fast switching and the introduction of commands line interface (CLI) modifications.

This document lists Cisco Express Forwarding CLI commands that are removed, replaced, new, and changed. The document lists and illustrates new commands, changed commands, and related command that are unchanged, to help you transition to the new CLI format.

Enhancements to Cisco Express Forwarding enable it to operate with the Multiprotocol Label Switching (MPLS) Forwarding Infrastructure (MFI) and guarantees consistency between Cisco IOS release trains. Cisco Express Forwarding infrastructure changes were introduced and implemented in the Cisco IOS 12.2(25)S-based releases and added for T releases in Cisco IOS Release 12.4(20)T.
