The NFFC maintains a Layer 3 switching table (MLS cache) for the Layer 3-switched flows. This feature allows IP traffic from multiple users or applications to a particular destination to be carried on a single flow if only the destination IP address is used to identify a flow. For example, HTTP Web packets from a particular source to a particular destination are in a separate flow from File Transfer Protocol (FTP) file transfer packets between the same pair of hosts.ДЇlows can be based on only Layer 3 addresses. Communication from a client to a server and from the server to the client is in separate flows. However, actual network traffic consists of many end-to-end conversations, or flows, between users or applications.ДЄ flow is a unidirectional sequence of packets between a particular source and destination that share the same protocol and transport-layer information. Layer 3 protocols, such as IP and Internetwork Packet Exchange (IPX), are connectionless-they deliver each packet independently of each other.

Multilayer Switching Protocol (MLSP)-The protocol running between the MLS-SE and MLS-RP to enable MLS.

Multilayer Switching-Route Processor (MLS-RP)-A Cisco router with MLS enabled.

Multilayer Switching-Switching Engine (MLS-SE)-A NetFlow Feature Card (NFFC)-equipped Catalyst 5000 series switch.The following terminology is used in the MLS chapters: 'Configuring IPX Multilayer Switching' module.'Configuring IP Multicast Multilayer Switching' module.'Configuring IP Multilayer Switching' module.

Procedures for configuring MLS and NDE on routers are provided in the following chapters in this publication: Procedures for configuring MLS and NDE on routers are provided in the 'Configuring IP Multilayer Switching' module. MLS uses NetFlow Data Export (NDE) to export the flow statistics. These statistics are used for identifying traffic characteristics for administration, planning, and troubleshooting. MLS also provides traffic statistics as part of its switching function. Packets that do not have a partial or complete switched path to reach their destinations still use routers for forwarding packets. The packet forwarding function is moved onto Layer 3 Cisco series switches whenever a partial or complete switched path exists between two hosts. MLS enables hardware-based Layer 3 switching to offload routers from forwarding unicast IP data packets over shared media networking technologies such as Ethernet.

Standard routing protocols, such as Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (Enhanced IGRP), Routing Information Protocol (RIP), and Intermediate System-to-Intermediate System (IS-IS), are used for route determination. MLS switches IP data packets between subnets using advanced application-specific integrated circuit (ASIC) switching hardware. MLS provides high-performance Layer 3 switching for Cisco routers and switches.

For configuration information for the CatalystВ 6000В series switch, see Configuring and Troubleshooting IP MLS on Catalyst 6500/6000 Switches with an MSFC or see the 'Configuring IP Multilayer Layer 3 Switching' chapter in the Catalyst 6500 Series Switch Cisco IOS Software Configuration Guide. Commands and configurations for Catalyst 5000 series switches are documented in the Catalyst 5000 Series Multilayer Switching User Guide and the CatalystВ 5000 Series Software Configuration Guide. The commands and configurations described in this guide apply only to the devices that provide routing services. Note This module is a brief summary of the information contained in the Catalyst 5000 Series Multilayer Switching User Guide. This chapter provides an overview of Multilayer Switching (MLS).
