High-Density,High Performance ATM and LAN Switching.
Incorporating support for the latest Asynchronous Transfer Mode (ATM) Forum speci?cations and building upon the Cisco Internetwork Operating System (Cisco IOS ?)software, the Catalyst ?
5500 switch offers a complete,sophisticated ATM feature set with the performance,scalability, and robustness required for production ATM deployment.
High-Performance Desktop and Campus
ATM Switching
The Catalyst 5500 switch features hot-swappable carrier modules (CAMs), each of which can support up to two hot-swappable port adapter modules (PAMs). The 5-Gbps shared memory, fully nonblocking ATM switching fabric of the Catalyst 5500 can support up to 32 155-Mbps ports or 8 622-Mbps ports.
Unlike other ATM switch architectures, however, the shared-memory fabric of the Catalyst 5500switch allows all the advanced traf?c management and other mechanisms of the switch to be implemented not on the interface modules,but on a ?eld-replaceable feature card on the switch module.This feature lowers the cost of the interface modules and facilitates the upgrading of the switch in case standards change or features become enhanced.
Building on the “plug-and-play” mechanisms of Cisco IOS software that allows Catalyst 5500 switches to come up automatically, all con?guration information for PAMs can be saved across hot swaps and switch reboots.Interface types are automatically discovered by the switch,precluding the need for manual con?guration. The Catalyst 5500 switch supports any combination of PAMs, allowing customers to con?gure their switches with only the number and type of interfaces required. The switch also has full support for ATM Forum-compliant User-Network Interface (UNI) and Network-to-Network Interface (NNI) signaling for multivendor interoperability and has support for such ATM internetworking protocols as LAN Emulation (LANE).
The Catalyst 5500 ATM Switching PAMs and LAN Emulation modules provide industry-leading connectivity into high-speed ATM networks
ATM Switch Processor Module
The ATM switch processor(ASP)module provides all the cell relay, signaling, and management processing functionality. The ASP supports the 5-Gbps, fully nonblocking, shared memory ATM switching fabric, with 65,536 cells of buffering.
The required,?eld-replaceable feature card,a daughter card of the ASP module,supports all advanced ATM switch functions, including intelligent packet discard, dual leaky bucket traf?c policing, and available bit rate (ABR) congestion control mechanisms.New versions of the feature card can be installed in the?eld as ATM standards evolve and the functionality is enhanced.
The ASP module’s high-performance, embedded
100-MHz MultiChannel Interface Processor (MIP) R4600 RISC processor, with its integral ATM access to the switch fabric, also delivers the high call setup rates and low call setup latencies required for the operation of signaling-intensive ATM internetworking protocols. Based on the design of the Route Switch Processor (RSP) module of the high-end Cisco7500series of multiprotocol routers,the ASP module offers many memory upgrade options for scalability, with internal, single in-line memory module (SIMM) banks for DRAM and Flash memory. Additional Flash ?les can be supported on its dual-height PC card slot.
The ASP module also supports an Ethernet port and dual serial ports for management access, with dual serial ports allowing for the connection of both a local terminal and a modem for remote access.
The ASP module also supports such standard Cisco IOS software functions as BOOTP, Telnet, and Trivial File Transfer Protocol (TFTP) and access control functions such as Terminal Access Controller Access Control System (TACACS) for robust administrative control. By building on the Cisco IOS software, the ASP module offers users the familiar command-line interface(CLI)of Cisco routers,with sophisticated online help and scripting capabilities,reducing training and deployment time.PAM (Port Adapter Module)
Each PAM delivers the following capabilities:
?Each port on a PAM can be set up as redundant links, which are exploited by the sophisticated ATM routing protocols of the Catalyst 5500 ASP module.
?Receive and transmit LEDs on each port give quick,visual indications of port status and operation,while support for comprehensive statistics gathering and alarm monitoring capabilities (building on the sophisticated manageability mechanisms of Synchronous Optical Network [SONET]/ Synchronous Digital Hierarchy [SDH]) allow for detailed network management.
?Each of the ports on the PAM can be con?gured to support a variety of clocking options: self-timing based on a Stratum 4 level clock; loop timing from the received data stream (ideal for public network connections); or timing synchronized to a selected master clock port, required in order to distribute a single clock across a network.
?A unique traf?c-pacing capability allows the aggregate output traf?c rate on any port to be set to a rate below the line rate;this feature is useful when communicating with a slow receiver or when connected to public networks with peak rate tariffs.
OC-12 ATM Multimode PAM
The multimode ?ber 622-Mbps SONET, Synchronous Transport Signal level 12, connected (STS-12c)/SDH Synchronous Transport Module level 4 (STM-4) PAM supports a single port.

Catalyst 5500 LANE
Cisco Systems’industry-standard Catalyst5500ATM LANE dual-physical sublayer(PHY)module integrates high-speed, switched LANs across an ATM campus network, providing legacy LANs with access to ATM-based services in the backbone. The module supports two (one primary, one secondary) 155-Mbps OC-3c interfaces with a wide range of media options—single-mode ?ber, multimode ?ber, and UTP Category 5.
A maximum of seven ATM dual-PHY LANE modules can be supported simultaneously in one Catalyst 5500 platform to provide redundant, fault-tolerant connections. The LANE module sets new standards for high performance, low-cost integration of switched Ethernet and Fast Ethernet over an ATM infrastructure.
Fault-Tolerant ATM Connectivity
The ATM dual-PHY LANE module delivers fault tolerance for critical network applications using several unique features:
“Dual Homed” ATM
Dual-PHY ATM allows network administrators to deploy redundant connections from one uplink port. Similar to Fiber Distributed Data Interface (FDDI) dual homing, the Catalyst 5500 dual-PHY LANE module provides link redundancy by duplicating the data link with a primary and secondary interface. If connectivity is lost on the primary interface because of either link failure or loss of Interim Local Management Interface (ILMI) communication, data connectivity automatically switches over to the redundant, secondary interface.
LANE Server Redundancy
Each Catalyst5500ATM dual-PHY LANE module delivers redundant LANE services using Cisco’s LANE Simple Server Redundancy Protocol (SSRP). LANE SSRP provides redundancy for all the server components in LANE—the LANE Con?guration Server(LECS),the LANE Server(LES), and the broadcast and unknown server (BUS). Cisco’s SSRP allows the enterprise-wide deployment of ATM by removing LANE servers as a single point of failure.
Wire-Speed Ethernet-to-ATM Connectivity
Multimedia and client/server applications require high throughput and low latency.Testing by Harvard University’s National Data Testing Laboratory (NDTL) has demonstrated that the Catalyst dual-PHY ATM LANE module provides low-latency, wire-speed performance to ATM OC-3c networks.
Scalable, Distributed LANE Servers
Unique among ATM edge devices, the Catalyst 5500 enhances ATM LANE network performance by delivering support for the entire range of LANE V.1.0servers.By using this feature, network administrators can easily distribute LANE services across each Catalyst ATM dual-PHY LANE module. For example, this feature allows scalable distribution of bandwidth-intensive LANE BUS services
for multimedia applications. Operating as a standalone LANE V.1.0 BUS, each Catalyst ATM dual-PHY LANE module can forward 120,000 pps.VLAN/ATM Integration
By using the industry-leading Cisco IOS?software, the Catalyst5500ATM dual-PHY LANE module extends virtual LAN(VLAN)capabilities throughout the network,spanning switched LANs and ATM-based services such as ATM servers by mapping VLANS to ATM LAN emulated LANs (ELANs).
