RAPIER 48w SWITCH

Switching Features

The Rapier 48w includes a suite of advanced

switching features such as IEEE 802.1Q VLAN

Tagging, IGMPv2, 802.1p Traffic Prioritization of

packets at Layer 3 and Layer 4, and broadcast

and multicast traffic control. The Quality of

Service (QoS) features offered by the Rapier

48w are particularly useful for Telco or Network

Service Provider applications.

WAN Support - Rapier Switch/Router

The Rapier 48w supports an optional Network

Services Module (NSM) with a variety of Port

Interface Cards (PICs) to provide Wide Area

Network connectivity for T1, DS3 and

Asynchronous communications.

Bandwidth Limiting

The Rapier 48w switch comes with asymmetric,

bidirectional bandwidth limiting at no additional

cost.This is an ideal feature for customers

needing to allocate the amount of bandwidth

on a per port basis. With bandwidth limiting,

network administrators can define throughput

levels for each port and control access based

on type of end user.These features are ideal for

managing different applications like VoIP, Web

browsing, video, email, and to regain control of

traffic across the network.The bandwidth

limiting on the Rapier 48w provides fine

granularity with the ability to define ingress

limits down to 64Kbps segments and egress

limits down to 1Mbps segments.The segment

definitions can be asymmetric and each port

can be set to different values. An additional

benefit is that loop back ports are not required.

Wirespeed Routing

A rich set of features is included to provide full

support for multimedia Layer 4 applications. All

switches include Layer 3 IP Static Routing, RIP,

RIPv2, IGMPv2 and OSPFv2 routing protocols.
