Chapter 1 Product Overview

Summary of Software Features

Resource Management

Resource management provides support for the following:

• Traffic categories:

–

Constant bit rate (CBR)

–

Real-time variable bit rate (VBR-RT)

–

Non-real time variable bit rate (VBR-NRT)

–

Available bit rate (ABR) + minimum cell rate (MCR)

–

Unspecified bit rate (UBR) + MCR

Note FC-PCQ-equipped systems only support MCR value 0 for ABR and UBR

traffic categories.

• Quality of service (QoS) guarantees with traffic policing and intelligent packet discard

• Connection admission control (CAC)

• Congestion control and traffic pacing

Note Some newer port adapters do not support traffic pacing.

• ABR with explicit forward congestion indication (EFCI) and relative rate (RR) marking

Note Relative rate marking of ABR traffic is not supported on the

Catalyst 8540 MSR.

Signalling and Routing

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 Signalling Protocol (IISP) routing protocol

• Single-level and full hierarchical Private Network-Network Interface (PNNI) routing protocol,
