Catalyst 5000 family switches support ATM uplink modules using unshielded twisted-pair (UTP), single-mode fiber (SMF), multimode fiber (MMF), and coaxial cables. This chapter describes the supported ATM modules and consists of these sections:
For specifications on all ATM modules (except LightStream 1010 ATM switching modules), see Appendix A, "Specifications."
For information on installing ATM modules, refer to Chapter 3, "Switching Module Installation."
The ATM modules run their own software images in addition to the supervisor engine software image. For additional information on the ATM module software, refer to the latest version of the Release Notes for Catalyst 5000 Family ATM Module Software Release x for release image names.
For information on configuring the ATM LAN Emulation (LANE), ATM DS3, and ATM OC-3 and OC-12 modules, refer to the Software Configuration Guide for your switch. For information on configuring LightStream 1010 ATM port adapters, refer to the LightStream 1010 Switch and Catalyst 8510 MSR Software Configuration Guide.
LANE is an ATM protocol that allows Ethernet end stations to communicate with ATM-attached file servers. It also functions as a backbone link allowing multiple Catalyst 5000 family Ethernet switches to connect together. LANE requires an ATM switch that supports User-Network Interface (UNI) 3.0 or 3.1 and point-to-multipoint signaling, for example, the Cisco LightStream 1010 ATM switch.
Multiprotocol over ATM (MPOA) provides a standards-based Layer 3 switching solution for ATM networks. MPOA enables the fast routing of internetwork-layer packets across a nonbroadcast, multiaccess (NBMA) network. MPOA replaces multihop routing with point-to-point routing using a direct virtual channel connection (VCC) between ingress and egress edge devices or hosts. An ingress edge device or host is the point at which an inbound flow enters the MPOA system; an egress edge device or host is the point at which an outbound flow exits the MPOA system.
These components are required for using MPOA across an NBMA network:
In an NBMA network, intersubnet routing requires that intermediate routers forward packets hop-by-hop. MPOA increases performance and reduces latencies by identifying the edge devices, establishing a direct VCC between the ingress and egress edge devices, and forwarding Layer 3 packets directly over this shortcut VCC, bypassing the intermediate routers. An MPC provides the direct VCCs between the edge devices or hosts whenever possible and forwards Layer 3 packets over these shortcut VCCs. The MPCs must be used with MPSs resident on routers.
This section describes the ATM LANE dual PHY modules.
Dual PHY modules provide two physical ports on each module; only one port is operational at a given time. The other port, if connected, is in standby mode and becomes active if the primary port link fails.
These modules require supervisor engine module software release 2.1(5) or later.
The ATM LANE dual PHY module (UTP), shown in Figure 6-1, provides one direct connection and one standby connection between the ATM network and the switch using two RJ-45 connectors. The module supports these features:
The LEDs provide status information for the module and the individual ATM port connections. The LEDs are described in the "ATM LANE Dual PHY Module LEDs" section.
The ATM LANE dual PHY OC-3 module (MMF), shown in Figure 6-2, provides one direct connection and one standby connection between the ATM network and the switch using two multimode, SC fiber-optic connectors.
The ATM LANE dual PHY module MMF supports these features:
The LEDs provide status information for the module and the individual port connections. The LEDs are described in the "ATM LANE Dual PHY Module LEDs" section.
The ATM LANE dual PHY OC-3 module SMF, shown in Figure 6-3, provides one direct connection and one standby connection between the ATM network and the switch using two single-mode (SC) fiber-optic connectors.
The ATM LANE dual PHY OC-3 module (SMF) supports these features:
The LEDs provide status information for the module and the individual port connections. The LEDs are described in the "ATM LANE Dual PHY Module LEDs" section.
Each ATM LANE dual PHY module contains a STATUS LED. When on, this LED indicates that the module is powered up and operational. It does not necessarily mean that the interface ports are functional or enabled.
Table 6-1 describes the LEDs for the ATM dual PHY modules.

The Catalyst 5500 switch supports the LightStream 1010 ATM switching modules, which include the ATM switch processor, carrier modules (CAMs), and port adapters. The ATM switch processor is a field-replaceable switch processor module that supports 5-Gbps shared memory. The ATM switch processor supports the feature card and high-performance reduced instruction set (RISC) processor that provides the central intelligence for the port adapters. Each CAM supports up to two hot-swappable port adapters for a maximum of eight port adapters per Catalyst 5500 switch and up to 32 OC-3 switched ATM ports.
The LightStream 1010 ATM switch provides switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, UTP, and coaxial cable.
