Performance
Allied Telesis' Rapier 48w Layer 3 10/100Mbps
switch delivers an unprecedented level of
integration and feature richness. With wirespeed
Layer 2 switching and wirespeed Layer 3 IP
routing on all ports, this switch is designed for
high-performance desktop connectivity,
workgroup and server farm aggregation or
backbone applications. In addition to the
impressive switching performance, the Rapier
48w brings a large set of optional high-level
Layer 3 features for more advanced networking
applications.
Progressive Features
The Rapier 48w Layer 3 switch comes complete
with the feature rich operating system
AlliedWare
®
, which includes Layer 3 IP Static
Routing, RIP, RIPv2,VRRP and OSPFv2 routing
protocols.
The Rapier 48w also includes an innovative "Find
Me" feature allowing an individual switch to be
located easily amongst other equipment.
Allied Telesis offers two optional feature licenses
with the Rapier 48w, a Full Layer 3 upgrade and
an Advanced Layer 3 upgrade.
The Full Layer 3 upgrade enables a set of
additional routing protocols such as:
• DVMRP

RAPIER 48w SWITCH
| Layer 3 Fast Ethernet 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.
