New and Changed Features, 12.1(7a)EY

This document contains a summary of the new and changed features for the Catalyst 8540, Catalyst 8510, and LightStream 1010 switch routers for Cisco IOS Release 12.(7a)EY.

Table 1 New and Changed Features in the Layer 3 Software Feature and Configuration Guide

Feature	Description	Chapter or Section
Embedded CiscoView Autonomous Device Package (ADP)	Provides another, more user-friendly, interface for configuring and managing the switch router apart from the existing conventional methods of terminal access.	"Configuring the Route Processor"
VC Bundling on the ATM uplink module.	Allows you to configure multiple VCs that have different QoS characteristics between any pair of ATM-connected routers.	Chapter 7, "Configuring ATM Uplinks."
Policy-Based Routing (PBR)	Policy based routing is a more flexible mechanism for routing packets than destination routing. It is a process whereby the router puts packets through a route map before routing them. The route map determines which packets are routed to which router next.	Chapter 11, "Configuring Quality of Service."
Tag Switching	Tag switching combines the performance and capabilities of Layer 2 (data link layer) switching with the proven scalability of Layer 3 (network layer) routing.	Chapter 13, "Configuring Tag Switching."

Table 2 New and Changed Features in the ATM Switch Router Software Configuration Guide

Feature	Description	Chapter or Section
Embedded CiscoView Autonomous Device Package (ADP)	Provides another, more user-friendly, interface for configuring and managing the switch router apart from the existing conventional methods of terminal access.	Chapter 2, "Understanding the User Interface."
Radius Support (TACACS+-like authentication)	RADIUS is a distributed client/server system that secures networks against unauthorized access.	Chapter 4, "Configuring System Management Functions."
SVC/Soft-VC/PVC preservation	This feature allows SVC, Soft VC, and PVC preservation upon a route processor switchover.	Chapter 6, "Configuring Virtual Connections."
Mobile Private Network-Network Interface (PNNI)	Distributes topology information between switches and clusters of switches. This information is used to compute paths through the network.	Chapter 10, "Configuring ATM Routing and PNNI."
Policy Based Routing	Policy based routing is a more flexible mechanism for routing packets than destination routing. It is a process whereby the router puts packets through a route map before routing them. The route map determines which packets are routed to which router next.	Chapter 12, "Configuring IP over ATM." This feature is also documented in the Configuring IP Routing Protocol-Independent Features section of the Cisco IOS IP and IP Routing Configuration Guide.
IP QoS Support	IP QoS is now supported on Gigabit processor interfaces.	Chapter 21, "Configuring Quality of Service."
Rate Limiting and Traffic-Shaping	Rate limiting is similar to the IOS committed access rate (CAR) feature. It limits the input or output transmission rate on an interface or subinterface. Traffic shaping is similar to the IOS GTS feature. It allows you to shape output traffic (egress traffic) on a per-physical port basis.	Chapter 23, "Configuring Rate Limiting and Traffic Shaping."
Traffic Shaping Carrier Module (Catalyst 8510 MSR)	The following new traffic shaping features are available: The Traffic Shaping Carrier Module (TSCAM) directs traffic through a particular interface on the module based on traffic class and priority. Traffic shaping is available for egress traffic on Fast Ethernet interface modules.	Chapter 22, "Configuring the ATM Traffic-Shaping Carrier Module."
Enhanced ATM Router Module and ATM Router Module Enhancements	The following enhancements are supported in this release: Soft PVCs on the ATM Router Module and the Enhanced ATM Router Module Support on the ATM Router Module for all classes of service, including UBR+, ABR, CBR, VB-RT, VB-NRT (8540 and 8510) Shaped tunnel support on the ATM Router Module Hierarchichal tunnel support on the ATM Router Module (8540 MSR)	Chapter 24, "Configuring ATM Router Module Interfaces."
