This chapter provides an introduction to the Catalyst 8540 MSR, and includes the following sections:
this document the Catalyst 8540 MSR is called the ATM switch router.
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. 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 nonblocking 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 4-port OC-12 module, or the SuperCAM, which in turn accommodates one or two port adapters, such as the 4-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 ATM switch router features the following available hardware components:
- Optional switch feature card, supporting usage parameter control (UPC) and statistics
- Optional network clock module
- Full-width 4-port OC-12 single-mode intermediate reach line module
- Support for the following LightStream 1010 ATM switch port adapters via the SuperCAM:
- 1-port OC-12 port adapters (multimode, single-mode, and single-mode long reach)
- 4-port OC-3 port adapters (multimode, single-mode, mixed, and UTP)
- 4-port DS-3/E3 port adapters
- 4-port T1/E1 port adapters
- 4-port T1/E1 circuit emulation service (CES) port adapters
The following sections provide a brief overview of the software features of the ATM switch router.
The ATM switch router provides the following self-configuring features:
- Preconfigured ATM address prefixes and MAC address, permitting small-scale ATM internetworks to be deployed prior to obtaining officially-allocated ATM addresses
- Automatic reassignment of addresses when reconfiguration is necessary
- Automatic recognition of port adapter types and ATM interface type using ILMI
- Automatic IP address configuration features, such as BOOTP
The ATM switch router supports connections with the following characteristics:
- Full 8-bit virtual path identifier (VPI) and 16-bit virtual channel identifier (VCI) with configurable boundaries.
- Up to 256,000 total virtual connections
- VC and virtual path (VP) switching, VP tunneling, VC merging, and VP multiplexing
- The following virtual connection types:
- F4 and F5 Operation, Administration, and Maintenance (OAM) segment and end-to-end remote deflect identification (RDI) and alarm indication signal (AIS)
Resource management provides support for the following:
The following signalling and routing features are supported:
- User-Network Interface (UNI) 3.0, 3.1, and 4.0
- Integrated Local Management Interface 4.0
- ATM network service access point (NSAP) and E.164 addressing
- Interim Interswitch Signaling Protocol (IISP) routing protocol
- Single-level and full hierarchical Private Network-Network Interface (PNNI) routing protocol, including PNNI complex node support
- Closed user groups (CUGs) for ATM virtual private networks (VPNs)
- ATM signalling and ILMI access lists with support for time of day-based policies
- ATM anycast
The following internetworking services are provided:
- LAN emulation configuration server (LECS), LAN emulation server (LES), and broadcast and unknown server (BUS) for Ethernet emulated LANS (ELANs)
- Cisco Simple Server Redundancy Protocol (SSRP) for LANE
- RFC1577 classical IP over ATM and Address Resolution Protocol (ARP) server and client
- Tag switching for Open Shortest Path First (OSPF) routing of IP packets
- ATM Circuit Emulation Service (CES) as defined by ATM Forum CES 1.0
Any interface on the ATM switch router can be synchronized to an internal source (system clock) or to an external source, such as another network. Synchronous, synchronous residual time stamp (SRTS), and adaptive clocking modes are supported for CES.
With the optional network clock module, the ATM switch router can be synchronized to a BITS source or to the module's own stratum 3 clock.
The following features provide support for managing the ATM switch router.
- Text-based command-line interface (CLI) for configuration and troubleshooting
- Configuration and system image files saved in NVRAM and Flash memory
- Boot from network or from Flash memory
- Upload and download system images using Trivial File Transfer Protocol (TFTP)
- Update hardware controller microcode independently of system image on channelized E1 port adapter
- In-band device network management using IP over ATM
- In-band device network management using LAN emulation client, RFC 1577 client, and RFC 1483 client
- Out-of-band device network management using Ethernet and console ports
- ATM forum and enterprise Management Information Bases (MIBs) including, but not limited to, the following:
- AToM MIB RFC1695
- SVC MIB
- ILMI MIB
- PNNIv1.0 MIB
- ATM Signaling and Diagnostic MIB
- ATM RMON MIB
- ATM Accounting MIB
- Port, VC, and VP snooping for monitoring and troubleshooting
- ATM accounting
- Remote and local periodic collection of records
- Accounting records for PVC/PVPs
- 5-second peak interval transmit and receive cell counter for PVC/PVP only
