Chapter 1
Introduction
Welcome to the Rapier Series Layer 3 Gigabit switch, combining wire speed
Layer 2 and Layer 3 IP switching, with a powerful multiprotocol routing
software suite.
Why Read This User Guide?
This User Guide describes how to get started accessing the switch’s Command
Line Interface (CLI) and its Graphical User Interface (GUI), and how to
configure the Layer 2 switching features. For more detailed descriptions of all
commands and display outputs see the Rapier Switch Software Reference. The
user guide is organised into the following chapters:
■Chapter 1, Introduction introduces the Rapier switch and gives an overview
of the features of the Rapier switch and its documentation.
■Chapter 2, Getting Started describes how to gain access to the switch’s
command line and graphical user interfaces.
■Chapter 3, Operating the Switch introduces general operation, management
and support features, including user authentication, loading and installing
support files, and SNMP MIBs.
■Chapter 4, Layer 2 Switching describes how to configure Layer 2 switching
features, including switch ports, VLANs and STP.
■Chapter 5, Layer 3 Switching describes how to use Layer 3 switching over
VLANs, including IP, Novell IPX and AppleTalk. Full descriptions of the
switch’s support for these protocols is found in the Rapier Switch Software
Reference.

Rapier Switch Software Release 2.2.1
C613-02013-00 Rev A
What Can the Rapier Switch Do?
The Rapier switch software support for the Rapier Series switches and their
expansion options provides wirespeed Layer 2 switching, including support
for Virtual LANs, wirespeed Layer 3 IP switching, and Layer 3 multiprotocol
routing.
Switching Features
The main Layer 2 features of the switch are:
■High performance, non-blocking, wire-speed Layer 2 switching (“Layer 2
Switching Process” on page 43).
■Packet Forwarding at wire speed (“The Forwarding Process” on page 45).
■Store and Forward switching mode.
■Autonegotiation of link speed and duplex mode for 10/100 Mbps speed on
all 100BASE TX ports (“Autonegotiation of Port Speed and Duplex Mode” on
page 29).
■Autonegotiation of duplex mode for 10/100 and gigabit Ethernet ports
(“Autonegotiation of Port Speed and Duplex Mode” on page 29).
■Automatic, configurable MAC address learning and ageing, supporting up
to 8191 MAC addresses per switch (“The Learning Process” on page 44).
■Switch Filtering (“Layer 2 Filtering” on page 46).
■Layer 3 Filtering (Switching chapter in Rapier Switch Software Reference).
■Broadcast Storm Protection (“Packet Storm Protection” on page 32).
■Virtual LANs defined by port membership (“Virtual LANs” on page 35).
■Spanning Tree Protocol (“Spanning Tree Protocol (STP)” on page 49).
■Priority tagging to support four QOS egress queues (“Quality of Service” on
page 48).
■Port trunking to spread traffic over several links (“Port Trunking” on
page 30).
■Port mirroring (“Port Mirroring” on page 33).
■IGMP (Internet Group Management Protocol) snooping (“IGMP Snooping”
on page 56).

Routing Features
In addition to Layer 2 and Layer 3 switching, the Rapier switch provides a
wide array of multiprotocol routing, security and network management
features.
IP routing is performed at wire-speed. Other Layer 3 routing is performed by the CPU,
and increasing the routing load on the CPU decrease its performance.
Some features require the addition of WAN interfaces via Network Service
Modules (NSMs) and Port Interface Cards (PICs) installed in the NSM bay on
the rear of the switch.
Features provided by the routing software suite include:
■IP version 4 routing.
■Network Address Translation (NAT) (not between switch ports)
■Dynamic IP Address Assignment
■IP Dynamic Filtering Firewall
■IP Multihoming
■IP RIP and IP RIPv2
■DNS Relay
■Demand IP
■IP Filtering (not between switch ports)
■IP Packet Prioritisation (not between switch ports)
■Generic Routing Encapsulation (GRE)
■Basic Rate and Primary Rate access to Integrated Services Digital Network
(ISDN) services, with dial-on-demand and channel aggregation.
■Time Division Multiplexing (TDM) over G.703 links
■Frame Relay
■X.25
■ARP, Proxy ARP and Inverse ARP address resolution protocols.
■BACP (Bandwidth Allocation Control Protocol)
■PPP Multilink
■PPP over Ethernet (PPPoE)
■Bandwidth on Demand
■CLI, PAP and CHAP
■Virtual Router Redundancy Protocol (VRRP) for fault tolerant internet
gateways (on NSM ports only)
■IPsec
■ISAKMP Key Management
■Data Compression
■Predictor Data Compression
■STAC Data Compression
■L2TP

Introduction 9

■A sophisticated and configurable event logging facility for monitoring and
alarm notification to single or multiple management centres.
■Triggers for automatic and timed execution of commands in response to
events.
■Scripting for automated configuration and centralised management of
configurations.
■Dynamic Host Configuration Protocol (DHCP) for automatically assigning
IP addresses and other configuration information to PCs and other hosts
on TCP/IP networks.
■Group management support for IP multicasting: IGMP version 2.
■Support for the Simple Network Management Protocol (SNMP), standard
MIBs and the Allied Telesyn Enterprise MIB, enabling the switch to be
managed by a separate SNMP management station.

server to the switch’s FLASH memory, and an HTTP server that serves web
pages from FLASH.
For a complete description of the switch’s routing software, see the Rapier
Switch Software Reference. Note that the Software Reference uses the word
“router” for the switch when it describes routing features.
Advanced Feature Licence AT-RPFL3Upgrade
