The switch is ideal for backbone deployment in small to mid- sized networks that require wire- speed Layer 3 performance but do not require the high 1. Mbps Ethernet port counts or Gigabit Ethernet density offered in the Catalyst 6. Catalyst 8. 50. 0 series of switches. Catalyst 2. 94. 8G- L3 Overview The Catalyst 2. G- L3 provides an aggregate throughput of more than 1. Mpps for Layer 3 switching. These data rates apply not only to IP and IPX traffic but also to IP multicast and bridged traffic and are a result of using high- speed application- specific integrated circuit (ASIC) technology on each port to perform true Layer 3 switching. The Catalyst 2. 94. G- L3 supports a high- performance architecture with 2. Gbps bandwidth. The switch fabric is capable of supporting all 4. Gigabit uplinks simultaneously at wire speed. The Catalyst 2. 94. G- L3 is housed in a 1. RU) chassis and can be provisioned with an optional external redundant power supply. It supports a 2. 2 Gbps shared- memory, fully non- blocking switch fabric, high- performance RISC processor that provides the routing intelligence and individual port- based ASICs for the Layer 3 switching. The Catalyst 2. 94. G- L3 uses Cisco Express Forwarding (CEF), which has been developed for the Cisco 1. GSR), the Catalyst 8. Cisco 7. 50. 0. This technology provides Layer 3 switching based on a topology map of the entire network that is distributed to each port- based ASIC, allowing it to make autonomous switching decisions without the involvement of a centralized CPU. Catalyst 2. 94. 8G- L3 Layer 3 Highlights—IP at Millions of Packets per Second The Catalyst 2. G- L3 provides a complete IP routing solution without sacrificing any of the services that are required to build a scalable network. The Catalyst 2. 94. G- L3 is a feature- rich switch with full Cisco IOS implementation that allows network managers to continue to administer and manage their networks as they do today while scaling their backbone bandwidths to gigabit speeds. The Catalyst 2. 94. G- L3 supports all the routing protocols that are used today in mid- sized 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 2. G- L3 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 2. G- L3 with its IPX wire- speed performance is also a full- fledged IPX router with the enhancements only Cisco IOS can offer. It provides basic services such as Novell Net. Work RIP and Service Advertising Protocols (SAPs), value- added routing protocols such as Novell Enhanced IGRP, as well as route distribution among all of these protocols. In addition, the Catalyst 2. G- L3 supports those features that help to make a large Novell network scale. These features include: Get Nearest Server (GNS) response filtering and round- robin GNS support. Novell RIPSAP, protocol, and Net. BIOS name filtering. Equal- cost path load sharing. Variable RIP and SAP timers. Novell Net. BIOS type 2. Novell- compliant IPX ping utility This feature set as well as the wire- speed IPX switching make the Catalyst 2. G- L3 unique in terms of switching platforms. IP Multicast Switching and Routing The Catalyst 2. G- L3 supports IP multicast at wire speeds across all its ports. As multicast applications such as Microsoft Net. Show and Net. Meeting 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 2. 94. G- L3 supports both Protocol- Independent Multicast (PIM) sparse and dense modes, and Distance Vector Multicast Routing Protocol (DVMRP) interoperability for legacy applications. The Catalyst 2. 94. G- L3 provides support for IGMP, Versions 1 and 2, and CGMP server capabilities for integrating IP multicast support with Catalyst wiring closet switches. 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. Fast Ether. Channel and Gigabit Ether. Channel Technologies The Catalyst 2. G- L3 supports both Fast Ether. Channel. Quality of Service The Catalyst 2. G- L3 incorporates a centralized non- blocking 2. Gb shared- memory switching fabric. The rich Qo. S capabilities of the switching fabric enable network managers to protect mission- critical applications by supporting delay- sensitive traffic while managing bandwidth in the campus backbone. The switching fabric supports per- flowqueuing (PFQ), differentiated delay priorities using a 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 Cisco. Assure Policy Networking, allowing an end- to- end Qo. S solution. Security The Catalyst 2. G- L3 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 2. 94. G- L3 supports both inbound and outbound access lists on its two Gigabit Ethernet interfaces. 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 Gigabit Ethernets allows network managers to prevent traffic both on egress as well as ingress on the 1. Ethernet ports. In addition, the Catalyst 2. G- L3 will have the capability to prevent traffic communication between 1. Ethernet ports. When enabled, users on the 1. Gigabit Ethernet ports and not to each other.
