Chapter1 Product Overview
Summary of Software Features
ATM Internetworking Services (Catalyst 8540 MSR)
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
• RFC 1577 classical IP over ATM and Address Resolution Protocol (ARP) server and client
• Tag switching for Open Shortest Path First (OSPF), Routing Information Protocol (RIP), and
Enhanced Interior Gateway Routing Protocol (EIGRP) routing of IP packets
• ATM Circuit Emulation Service (CES) as defined by ATM Forum CES 1.0
• RFC 1483 multiprotocol encapsulation over ATM
ATM Internetworking Services (Catalyst 8510 MSR and LightStream 1010)
The following internetworking services are provided:
• LAN emulation configuration server (LECS), LAN emulation server (LES), and broadcast and
unknown server (BUS) for Ethernet and Token Ring emulated LANs (ELANs)
• Cisco Simple Server Redundancy Protocol (SSRP) for LANE
• RFC 1577 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

Network Clocking
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 residual time stamp (SRTS), and adaptive
clocking modes are supported for CES.
With the optional network clock module on the Catalyst 8540 MSR, the ATM switch router can be
synchronized to a BITS source or to the module’s own stratum 3 clock.
Management and Monitoring
The following features provide support for managing the ATM switch router:
• Text-based command-line interface (CLI) for configuration and troubleshooting
• Simple Network Management Protocol (SNMP) agent provides dynamic status, statistics, and
configuration information
• 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)
