3 C O M ® X R N ™ I N T E R C O N N E C T K I T D ATA S H E E T
An XRN Distributed Fabric using 3Com Switch 4060s,
the XRN Interconnect Kit, and the 5m Interconnect Cable

Product Overview

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.
Advanced Multilayer Switching Functionality
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 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.
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.
