Summary of Software Features
Summary of Software Features
The following sections provide a brief overview of the software features of the ATM switch router and
include the following:
• System Availability (Catalyst 8540 MSR) on page 1-4
• ATM Addressing and Plug-and-Play Operation on page 1-4
• Connections on page 1-5
• Resource Management on page 1-5
• Signalling and Routing on page 1-6
• ATM Internetworking Services (Catalyst 8540 MSR) on page 1-6
• ATM Internetworking Services (Catalyst 8510 MSR and LightStream 1010) on page 1-7
• ATM Internetworking Services (Catalyst 8540 MSR) on page 1-6
• Management and Monitoring on page 1-7
• Available Network Management Applications on page 1-8
The ATM switch router provides Enhanced High System Availability (EHSA) during hardware and
software upgrades as well as fault resistance by means of the following features:
• Dual power supplies
• Dual route processors (CPUs)
• Switching fabric with optional spare switch processor
• Optional dual network clock modules
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.
System Availability (Catalyst 8540 MSR)
The ATM switch router provides Enhanced High System Availability (EHSA) during hardware and
software upgrades as well as fault resistance with the following features:
• Dual power supplies
• Dual route processors (CPUs)
• Switching fabric with optional spare switch processor
• Optional dual network clock modules
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.
