This chapter provides an introduction to the Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010 ATM switch routers.
This chapter includes the following sections:
This section provide an overview of the hardware available for the Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010 ATM switch routers and includes the following:
The ATM switch router uses a 13-slot, modular chassis featuring dual, fault-tolerant, load-sharing AC or DC power supplies. Slots 4 and 8 are occupied by the dual, field-replaceable route processors, which perform central processing functions and provide redundancy. The route processors can also accommodate the network clock module, which features a stratum 3 oscillator and two building integrated timing supply (BITS) ports. Slots 5, 6, and 7 are occupied by either two or three switch processors, for a 20-Gbps non-EHSA or 20-Gbps EHSA switch fabric. The switch processors also accommodate the switch processor feature card.
The remaining slots hold either a full-width module, such as the new four-port OC-12 module, or the carrier module, which in turn accommodates one or two port adapters, such as the four-port OC-3 port adapters. Along with other available interfaces, the ATM switch router provides switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.
The Catalyst 8540 MSR features the following available hardware components:
The Catalyst 8510 MSR and LightStream 1010 ATM switch routers both use a five-slot, modular chassis featuring the option of dual, fault-tolerant, load-sharing AC or DC power supplies. A single, field-replaceable processor module supports both the 5-Gbps shared memory and the fully nonblocking switch fabric. The processor also supports the feature card and high performance Reduced Instruction Set (RISC) processor (CPU) that provides the central intelligence for the device. The remaining slots support up to four hot-swappable carrier modules. Each carrier module can hold up to two hot-swappable port adapters for a maximum of eight port adapters per switch, supporting a wide variety of desktop, backbone, and wide-area interfaces.
The ATM switch provides switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.
The Catalyst 8510 MSR and LightStream 1010 ATM switch routers are equipped with one of the following combinations of processor (CPU) and feature card:
The Catalyst 8510 MSR is equipped with the MSRP.
ASP-B with FC-PCQ and ASP-C with FC-PCQ are functionally equivalent, offering the same features and performance. FC-PFQ, however, provides an enhanced feature set, including advanced traffic management. ASP-B and ASP-C, equipped with FC-PFQ, also provide identical functionality for ATM applications. In the future, however, ASP-C with FC-PFQ provides the additional capability for supporting both ATM and Layer 3 switching on the same platform. ASP-C with FC-PFQ and the MSRP, used in the Catalyst 8510 MSR, are identical.
For additional information, refer to the Processor Installation Guide.
The ATM switch router supports the following port adapters:
The following sections provide a brief overview of the software features of the ATM switch router and include the following:
The ATM switch router provides EHSA during hardware and software upgrades as well as fault resistance by means of the following features:
In the event one of the route processors becomes unavailable because of a failure or software upgrade, the secondary route processor takes over. To support switching fabric availability, an optional third switch processor, running in standby mode, takes over if one of the other switch processor cards fails. Additionally, the optional network clock modules are able to retain clock configuration should one of the modules fail.
The ATM switch router provides High System Availability (HSA) during hardware and software upgrades as well as fault resistance with the following features:
In the event one of the route processors becomes unavailable due to failure or for software upgrade, the secondary route processor takes over with zero boot time. To support switching fabric availability, an optional third switch processor, running in standby mode, takes over if one of the other switch processor cards fails. Finally, the optional network clock modules are able to retain clock configuration should one of the modules fail.
The ATM switch router provides the following self-configuring features:
