3Com®XRN™Interconnect Kit
XRN™Technology
The 3Com®eXpandable Resilient
Networking (XRN™) Interconnect Kit
enables two SuperStack®3 Switch 4900
family or two 3Com®Switch 4050 and
4060 switches to build an XRN Phase
One Distributed Fabric.
Pay As You Grow
3Com XRN technology lets customers
cost-effectively upgrade their existing
core based on a single SuperStack 3
Switch 4900 or 3Com Switch 4050
and 4060, to a high-performance,
high-availability, 48-port multilayer
Gigabit switching core.
Network Level Availability
XRN technology lets customers design
and implement core Gigabit backbones
that feature no single point of failure—
a safeguard against hardware, cabling,
or software failure.
Performance and Scalability
The distributed nature of XRN
technology takes full advantage of the
high-performance, non-blocking
switching capacity of each switch in the
Distributed Fabric—yielding aggregate
forwarding capacity in excess of
70Mpps across the 48 switched Gigabit
ports.
Manageability
XRN Technology enables unprecedented
levels of manageability across the two
switches in the Distributed Fabric, by
offering "plug and play" setup of the
Fabric, single IP address management,
and fabric-wide configuration of all
management, system and port features.
High Performance Layer 3 Switching
An XRN Distributed Fabric uses the
Layer 3 switching capabilitiies of both
switches for greater performance and
scalability but without the complexity
of managing two separate routers.
Distributed Link Aggregation
Configuring ports of an aggregated link
across both switches in a Distributed
Fabric enables wiring closets to be dual-
homed for greater availability and
performance across the network back-
bone.
Flexibility and Migration
An XRN Phase One Distributed Fabric is
built with any combination of SuperStack
3 Switch 4900 family or 3Com Switch
4050 and Switch 4060.
Advanced Security capabilities
Security features such as RADIUS Client
and Routed Access Control Lists ensure
authorized user access to network
resources. Also, Application Filtering
lets the XRN Distributed Fabric identify
and discard unauthorized applications.
Powerful Management
3Com Network Supervisor fully supports
XRN Phase One fabrics and provides
discovery, mapping, monitoring, and
alerting for easy network administration.
Network-wide switch traffic prioritiza-
tion can also be performed. The 3Com
Network Supervisor Advanced Package
increases the number of IP devices
supported and provides advanced con-
figuration capabilities such as bulk
software upgrades.
Key Benefits
3COM®XRN™INTERCONNECT KIT DATA SHEET
The main components of the XRN
technology are as follows:
Distributed Device Management (DDM)
DDM lets customers configure and
manage the Distributed Fabric as a
single entity via the CLI, Web inter-
face, or SNMP. In the event of failure
in one of the switches, management
access to the remaining switch is
retained on the same IP address.
Distributed Link Aggregation (DLA)
DLA enables wiring closet switches or
hosts to create Aggregated Links that
are dual-homed across the switches in
the Distributed Fabric. Should a port
in the Aggregated Link fail, traffic
will be forwarded via the remaining
ports. DLA provides Intelligent Local
Forwarding—enabling each switch in
the Fabric to make its own forwarding
decisions, without sending traffic
across the Fabric Interconnect.
Distributed Resilient Routing (DRR)
DRR lets both switches in the
Distributed Fabric act as a single
logical router. The switches use the
same router interfaces and mirror
each other's routing tables. This pro-
tects the network against unit failure
and enables each switch to locally
route traffic for greater Layer 3 for-
warding performance.
XRN Phase One, enabled by the
3Com XRN Interconnect Kit, is the
first evolution of XRN technology. It
is supported on the 3Com Switch
4050 and 4060, and the SuperStack 3
Switch 4900 family. XRN Phase One
lets customers build a Distributed
Fabric with two 3Com switches which
are managed as a single logical entity.
A Fabric retains the software
capabilities and functionality of its
component switches.

XRN Technology Hierarchy
"3Com offers a revolutionary
approach to build enterprise
LAN cores with innovative
technology that breaks new
ground in the networking
industry."
Zeus Kerravala, vice president of
Enterprise Infrastructure, Yankee Group
3Com eXpandable Resilient
Networking (XRN™) is a patented
technology that lets enterprise
customers design and implement
affordable, high-availability Gigabit
Ethernet core and aggregation back-
bones that provide exceptional
performance and flexibility. XRN
technology lets multiple Gigabit Layer
3 switches function as a single multi-
layer switching entity called a
Distributed Fabric. The Fabric is
managed and configured as a single
device, even though each switch in
the Distributed Fabric makes its own
Layer 2 and Layer 3 forwarding
decisions.
The XRN technology hierarchy is
shown in figure 1.
XRN Technology Overview
3COM®XRN™INTERCONNECT KIT DATA SHEET
An XRN Phase One Distributed
Fabric retains the functionality of its
component switches. 3Com Gigabit
Multilayer Switching Software v3.0
provides management and multilayer
switching functionality for the XRN
Fabric. VLAN tagging, Multicast
Filtering, Spanning Tree and Rapid
Spanning Tree (802.1w) provide XRN
Fabrics with rich Layer 2 features for
demanding Gigabit backbones.
Distributed Link Aggregation using
IEEE 802.3ad/LACP enables automatic
configuration of aggregated links
across both switches in the Fabric for
greater levels of resiliency and perfor-
mance.
A Distributed Fabric supports Layer 3
switching for IP networks, enabling
unicast IP routing supporting static
routes, RIP and RIPv2, IP Multinetting,
Classless Interdomain Routing (CIDR)
and UDP Helper.
In addition, DDR provides distributed
routing functionality and resiliency
across a fabric. Enhanced Quality of
Service provides multiple priority
queues per port, traffic classification
and prioritization, using multilayer
packet information and queue
scheduling based on WRR. Priority
Remarking, Application Filtering and
Webcache Redirection for enhanced
traffic control across the backbone
may also be available. Greater security
is provided by RADIUS Client for
management access, Application
Filtering for controlling rogue
applications across the backbone
and Routed Access Control Lists.
Using DDM, true plug-and-play
support, single IP address manage-
ment, single step software upgrades,
and fabric-wide configuration via
SNMP, Web interface, and the CLI ease
device management in the Distributed
Fabric. In addition, the Fabric supports
7 groups of RMON and RMON event
notification via an integrated SMTP
client.

The 3Com XRN Interconnect Kit
includes two XRN modules, a 1 meter
cable (an optional 5m cable is also
available), and version 3.0 of the
3Com Gigabit Multilayer Switching
Software.
When installed, it provides a high-
performance 8Gbps connection which
enables configuration and manage-
ment of the Distributed Fabric as
single switching entity. If one switch
in the Fabric fails, management and
Layer 2 and Layer 3 switching are
automatically restored on the remaining
switch.
In the unlikely event of a failure in an
XRN interconnect module or cable,
DLA continues to provide an active
path allowing the switches to
communicate, and DRR ensures that
only one of the switches continues to
route—eliminating the possibility of
duplicate routers on the network.
XRN technology can be deployed at
all areas of an enterprise network: at
the core backbone with the 3Com
Switch 4060 and Switch 4050; the
server farm with a SuperStack 3
Switch 4924; in the wiring closet
using the SuperStack 3 Switch 4900
and 4900SX as Gigabit aggregation
switches.
