Introducing the Catalyst 4000 Integrated Layer 3 Services Module

The Catalyst 4000 Layer 3 services engine is packaged on a switching line card with 32-port, 10/100 Mbps Fast Ethernet and two-port 1000 Mbps Gigabit Ethernet using modular gigabit interface converter (GBIC) flexibility. When this Layer 3 services engine is installed in a chassis, silicon-based multiprotocol routing and Layer 3 QoS is possible for all ports in the system (including legacy switching line cards). This solution is ideal for wiring closet deployment in small, medium-sized, or large networks that require wire speed Layer 3 system uplink performance. Another application for the Catalyst 4003 is for server farm aggregation where Layer 3 services are required.

Catalyst 4000 Layer 3 Services Engine Overview

The Catalyst 4000 family Layer 3 engine provides an aggregate throughput of 6 million packets per second (pps) for Layer 3 switching that can scale higher by adding multiple Layer 3 services modules. This data rate applies tIP, IPX, IP multicast and bridged traffic, and is a result of using high-speed application-specific integrated circuit (ASIC) technology to perform true Layer 3 switching. The Catalyst 4000 family`s Layer 3 services engine supports a high-performance architecture with 8 Gbps bandwidth. The switch fabric is capable of supporting all system ports with high-speed Layer 3 routing and QoS marking. The switch fabric is capable of supporting Layer 3 on dual Gigabit Ethernet uplinks simultaneously at wire rate.

The Catalyst 4000 family Layer 3 router is supported in both the Catalyst 4003 or Catalyst 4006 chassis. It supports a high-performance RISC processor, which provides the routing intelligence and optimized GE ASICs for the Layer 3 switching. The Catalyst 4000 family Layer 3 engine uses Cisco Express Forwarding (CEF). This technology provides Layer 3 switching based on a topology map of the entire network that is distributed to multiple ASICs, allowing autonomous switching decisions without the involvement of a centralized CPU.

Catalyst 4000 Family with Integrated Layer 3 Services Features at a Glance

• High-performance, scalable 6 Mpps Layer 3 services engine of IP, IPX, and IP multicast protocols

• Up to 224 ports 10/100 Mbps Fast Ethernet plus dual Gigabit Ethernet uplinks (GBIC slot), including previously deployed Catalyst 4000 line cards

• High-performance CPU with Cisco IOS, system software

• Quality of service (QoS), multiple queues with Weighted Round Robin (WRR) scheduling

• Comprehensive management tools based on standard CiscoWorks2000 applications

• Hardware-based Access Control List (ACL) support on dual Gigabit Ethernet uplinks

• Inter-switch link (ISL) and 802.1Q trunking on dual Gigabit Ethernet uplinks

Quality of Service

The Catalyst 4000 family Layer 3 enhances the Catalyst 4000 family`s centralized, nonblocking 24 Gbps shared-memory switching fabric. The rich QoS capabilities of the switching fabric enable network managers to protect mission-critical applications by supporting delay-sensitive traffic, while managing bandwidth in the campus network. The switching fabric supports Per-Flow Queuing (PFQ), differentiated delay priorities using a Weighted Round Robin (WRR) scheduler for delay-sensitive applications, and differentiated loss priorities for managing congestion and traffic policing and shaping. The fast packet memory embedded in the switching fabric is allocated dynamically on a per-queue (flow) basis. This dynamic allocation used in conjunction with user- defined queue thresholds and configurable queue scheduling weights ensures that time-sensitive traffic is handled properly with no packet loss. These thresholds and queuing weights can be dynamically adjusted with CiscoAssure Policy Networking, allowing an end-to-end QoS solution.

IP at Millions of Packets per Second

The Catalyst 4000 family Layer 3 provides a complete IP routing solution without sacrificing any of the services required to build a scalable network. The Catalyst 4000 family includes feature-rich switches with integrated full Cisco IOS implementations that allow network managers to continue to administer and manage their networks as they do today, while scaling their wiring closet QoS bandwidths to gigabit speeds. The Catalyst 4000 family supports all the routing protocols that are used today in campus networks. These protocols include:

• Interior Gateway Routing Protocol (IGRP)

• Enhanced IGRP (EIGRP)

• Open Shortest Path First (OSPF)

• Routing Information Protocol (RIP) Versions 1 and 2

• Static routes

• Route redistribution

In addition to these routing protocols, the Catalyst 4000 family Layer 3 Services supports all the additional protocols necessary to build scalable, reliable networks, including:

• Hot Standby Router Protocol (HSRP)

• Internet Group Management Protocol (IGMP) 1 and 2

• Dynamic Host Configuration Protocol (DHCP) Relay

• Cisco Group Management Protocol (CGMP)

• Internet Control Message Protocol (ICMP)

• Gateway Discovery Protocol (GDP)

• ICMP Router Discovery Protocol (IRDP)

• Bootstrap Protocol (BOOTP) Relay

IPX Switching Feature Set

The Catalyst 4000 family Layer 3 services is also a full-fledged Cisco IPX, router with the enhancements only Cisco IOS can offer. It provides basic services such as Novell NetWork RIP and Service Advertising Protocols (SAPs), value-added routing protocols such as Netware Link

Services Protocol (NLSP) and Novell Enhanced IGRP, as well as route distribution among all of these protocols. In addition, the Catalyst Layer 3 services support features that help scale a large Novell network. These features include:

• Get Nearest Server (GNS) response filtering and round-robin GNS support

• Novell RIP

• SAP, protocol, and NetBIOS name filtering

• Equal-cost path load sharing

• Variable RIP and SAP timers

• Novell NetBIOS type 20 propagation support for legacy applications that continue to be mission critical

• Novell-compliant IPX ping utility

This feature set, as well as the wire-speed IPX switching uplinks, make the Catalyst 4000 family Layer 3 unique in terms of wiring closet switching solutions.

IP Multicast Switching and Routing

The Catalyst 4000 family switches support IP multicast at high-speeds across all ports. As multicast applications such as Microsoft NetShow and NetMeeting become more widely deployed, end-to-end multicast support becomes increasingly important with multicast routing protocols that are integral to a consistent end-to-end multicast solution. The Catalyst 4000 family with Layer 3 services switching supports both Protocol Independent Multicast (PIM) sparse and dense modes and Distance Vector Multicast Routing Protocol (DVMRP) interoperability for legacy applications. The Catalyst 4000 family Layer 3 provides support for IGMP, Versions 1 and 2, and CGMP server capabilities for integrating IP multicast support. These protocols are necessary not only for IP multicast clients to join groups but also for efficient leave processing, which saves bandwidth and end-station CPU cycles.

Security

The Catalyst 4000 family Layer 3 Services module has the ability to prevent security breaches via the use of both IP and IPX access lists. This is useful in preventing users from accessing certain applications or services. The Catalyst 4000 family Layer 3 Services module supports both inbound and outbound access lists on both its Gigabit Ethernet interfaces on the Layer 3 Services switching line card. These access lists can be defined similar to any Cisco IOS router as standard IPX access lists as well as standard and extended IP based access lists. Having both inbound and outbound control of packets on the line card-based Gigabit Ethernet ports (i.e. two internal and two external ports) allows network managers to prevent traffic both on egress as well as ingress.

VLAN Trunking

The Catalyst 4000 family Layer 3 supports both inter-switch link (ISL) and 802.1Q trunking on the Layer 3 module`s dual Gigabit Ethernet uplink ports. In addition, 802.1Q trunking is supported on all 10/100 ports.

Fast EtherChannel and Gigabit EtherChannel Technologies

The Catalyst 4000 family Layer 3 supports Fast EtherChannel (R) and Gigabit EtherChannel technologies, allowing network managers to group up to eight of the Ethernet ports into an intelligent high-speed channel.

Comprehensive Network Management of CiscoWorks2000

Catalyst 4003 and 4006 switches are managed by the powerful CiscoWorks2000 network management suite (option). The Essentials product suite leverages the power of the intranet with browser-based access anywhere within the network. Network managers can walk up to any browser console, simply identify who they are via the access control interface, and immediately begin checking on the uptime of each device, the active software versions that are running the Catalyst 4003 or 4006. For drill-down real-time device status information, the network operations staff can launch the award-winning CiscoView application from their fault-management stations and at a glance check on power supplies, line cards, and the operational status of each port.

Key Features and Benefits

• Proven, End-to-End Software Architecture

  Emerging applications such as video, web and multimedia require advanced functionality in the wiring closet by leveraging comprehensive software integration and extending Layer-2 and Layer-3 services from the network core. The Catalyst 4000 family delivers these advanced wiring closet features by utilizing the same software image as the Catalyst 5000/5500 series switches. By leveraging the Catalyst 5000/5500 IOS software, network administrators can take advantage of years of real world network deployment and experience at networks ranging in size from 10-20 users to over 10,000. The result is a scalable, time proven software architecture with a minimum of training requirements.

• Advanced Network Services for the Wiring Closet

  Exponential growth in network traffic due to emerging applications has driven the development of Cisco`s software architecture, making it the reference standard for switched enterprise LANs. It lets network managers build a fully integrated switched LAN infrastructure that handles wire-speed Layer-2 and Layer-3 switching from end tend. The result is the elimination of bottlenecks in key areas of the enterprise LAN - desktops, servers and the core. Cisco delivers specific software features for the wiring closet that deliver on this promise, including the following: multimedia support, scalability, protocol filtering, high availability, and superior network management. Let`s look at these in more detail.

• Multimedia Support via IP Multicast

  The need for distance learning, video and audio to the desktop, large file transfers, and financial market data feeds, drives many corporations to new levels. The architecture of the Catalyst 4000 Family of campus LAN switches is especially suited to handle the IP unicast and multicast traffic support these applications demand. The Catalyst 4003 can transmit traffic from multiple multicast sessions at wirespeed out of all ports simultaneously, using Cisco`s Group Multicast Protocol (CGMP) in conjunction with industry standard IP Multicast protocols such as Internet Group Multicast Protocol (IGMP) and Protocol Independent Multicasting (PIM).

• Scalability

  As the demand for network bandwidth increases, network administrators require the ability to intelligently provide differentiated services based upon protocol or application.

• Protocol Filtering

  Catalyst 4000 family switches automatically detect what type of client stations (i.e., IP and IPX) are attached, by reading the header of all packets originating from the client stations. The switch will automatically shield client stations from unnecessary protocol broadcasts. For example, an IP-only client station will no longer see IPX broadcasts from IPX stations within the same Layer-2 broadcast domain. Protocol filtering in the wiring closet improves bandwidth efficiency and end-station performance, by freeing the end-station CPU from interrupts, to process unnecessary broadcast traffic.

• Quality- of- Service: Content Networking Ready

  Quality-of-service (QoS) functionality must be supported from the wiring closet through the Wide Area Network to be an effective tool; the Catalyst 4000 delivers QoS with two priorities. Managing the Catalyst 4000 with the upcoming Content Networking management applications allows network managers to map business requirements to networking policies. This secures access to network resources, and quality of service (QoS) from the wiring closet to the backbone.

• High Availability

  Layer-2 wiring closet switches use the Spanning-Tree Protocol to recover from link failure and guard against data loop formation in the network. When the primary link fails, the spanning tree algorithm selects a new path, and ensures there is never more than one path connecting two points. The convergence time of the Spanning-Tree Protocol is normally 50 seconds. This long delay can cause many client/server sessions to time-out. Cisco has developed mechanisms to greatly improve recovery from failure, using Spanning-Tree Protocol convergence on its LAN switches. With the Cisco features PortFast, Fast/Gigabit Etherchannel and UplinkFast, network failure from the wiring closet to the backbone will converge in less than 3 seconds after a fault on an uplink.

• Network Management

  Cisco`s powerful CiscoWorks 2000 network management products manage Catalyst 4000 family products. These management products focus on day-to-day network operation functions such as:

  • Checking on device availability and configuration changes

  • Provisioning of VLANs across multiple devices concurrently

  • Representation of Layer-2 networks both physically and logically

  The Essentials product suite leverages the power of the intranet with browser-based access anywhere within the network. Network managers can walk up to any browser console, simply identify who they are via the access control interface, and immediately begin checking the up-time of each device, the active software versions that are running the Catalyst 4000s, and print a year 2000 compliant report. For drill down real-time device status information, the network operations staff can launch Cisco`s award winning CiscoView application from their fault management station, and at a glance check on the health of the power supplies, line cards, and the operational status of each port.

  For more sophisticated network-wide information, network managers can launch the CiscoWorks for Switched Internetworks-Campus (CWSI-Campus) product bundle, which automatically discovers the physical and logical representations of the Catalyst switch networks. This object-based discovery system offers detailed information on the location and type of each switch within the network, the type of links that connect the switches together, and displays integrity reports on the configurations between each switch. All of this information is provided graphically within the topology interface with search and location utilities. This topology interface offers a convenient launching point for other applications within CWSI-Campus including the RMON based traffic analysis application, the network-wide user location application, and the VLAN application which displays the logical configuration and spanning tree forwarding path information. All Catalyst switches are fully integrated into Cisco`s CWSI network management platform, enabling complete Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON) control.
