Key Benefits XRN Technology
3Com XRN™(eXpandable Resilient
Networking) technology allows
implementation of high availability
configurations using two intercon-
nected Switch 4050s or Switch 4060s,
scaling the backbone to 48 wirespeed
Gigabit Layer 3 switching ports.
Performance
3Com’s custom ASIC architecture
delivers 56 Gbps of multilayer switch-
ing capacity, provides wirespeed
performance across all ports, with a
forwarding rate of more than 40 Mpps,
minimizing network congestion.
Reliable and Serviceable Hardware
A durable, 2RU metal chassis offers
high availability hardware features
such as redundant, load sharing and
hot-swappable power supplies, in
addition to hot-swappable fan trays
and GBIC transceivers.
High Availability Features
High availability software and man-
agement features, including Link
Aggregation, Resilient Links, Spanning
Tree and Rapid Spanning Tree (802.1w),
seven groups of RMON, and email
alerts, facilitate highly available net-
work designs for the core backbone.
Advanced Network Control
Advanced Layer 2 and Layer 3 func-
tionality such as multicast filtering,
virtual LANs, and multilayer traffic
classification and prioritization improve
traffic control across the network.
Layer 3 Switching
Layer 3 switching capabilities such as
support for IP unicast routing using
static routes, RIP/RIPv2, CIDR, and
UDP Helper, enhance performance,
provide network control and security,
and enable logical network segmentation.
Advanced Security Capabilities
Security features such as Radius client
support and Routed Access Control
Lists ensure authorized user access to
network resources. Application
Filtering enables the switch to identify
and discard unauthorized applications
from consuming network bandwidth.
Powerful Management
3Com®Network Supervisor (trial copy
included) discovers, maps, monitors,
and issues alerts for easy network
administration. An intuitive interface
eases network-wide setup of switch
traffic prioritization. The 3Com
Network Supervisor Advanced Package
(separately sold) provides advanced
configuration capabilities such as
bulk software upgrades.
Webcache Support
Web traffic can be automatically redi-
rected to a 3Com SuperStack®3
Webcache, improving web performance
and easing network administration.
Flexibility
A combination of integrated
1000BASE-SX, 10/100/1000 and GBIC
ports supports a variety of cabling
plants and network designs. An
optional expansion slot accommodates
a 4-port Gigabit module for even
greater flexibility.

High Availability
Without Compromise
3Com’s Gigabit Multilayer Switching
software, supported by the 3Com Switch
4050 and Switch 4060, provide feature
rich Layer 2 functionality, Layer 3
switching for IP networks, and
enhanced QoS services.
Advanced Layer 2 features such as
VLAN tagging, Multicast Filtering,
Link Aggregation, Spanning Tree,
Rapid Spanning Tree (802.1w), and
support for seven groups of RMON
provide a rich feature set for demand-
ing Gigabit backbones.
The 3Com Switch 4050 and Switch
4060 support four priority queues per
port, Weighted Round Robin queue
scheduling, traffic classification and
prioritization based on Layer 2 (physi-
cal port, 802.1p, Ethertype), Layer 3
(DSCP, IP host address and IP subnet)
and Layer 4 (TCP/UDP) information.
Priority remarking for DSCP and
application filtering is also available
for enhanced traffic control across the
backbone.
These switches also support Layer 3
switching for IP networks, enabling a
wide array of services such as unicast
IP routing supporting static routes,
RIP and RIPv2, IP Multinetting,
Classless Interdomain Routing (CIDR)
and UDP Helper. Routed Access
Control Lists based on IP address
information can also be used to provide
enhanced control and security across
a Layer 3 switching implementation.
For more efficient use of Internet
bandwidth, the 3Com Switch 4050
and Switch 4060 enable automatic
redirection of web traffic to 3Com
SuperStack 3 Webcache appliances,
enhancing overall web performance.
The Switch 4050 and Switch 4060
provide enhanced device management
functionality through support for
BootP/DHCP clients, seven groups of
RMON, and RMON event notification
via an integrated SMTP client.

Advanced Multilayer
Switching Functionality
High availability is one of the key
requirements for connectivity in the
core backbone of enterprise networks.
The 3Com Switch 4050 and Switch
4060 deliver this capability through a
combination of hardware and software
features that provide redundancy, reli-
ability, serviceability, and high
network-level availability without
compromising performance or func-
tionality.
The Switch 4050 and Switch 4060
support two redundant, load sharing
and hot-swappable power supplies in
addition to hot-swappable fan trays
and GBIC transceivers. Network-level
availability features such as Link
Aggregation and Rapid Spanning Tree
enable resilient data paths across the
network for even greater fault toler-
ance.
XRN Technology
Companies no longer have to spend a
fortune or double their IT staff to
ensure that their essential business
systems are continuously available to
users who need them. eXpandable
Resilient Networking (XRN) technol-
ogy from 3Com is a new LAN core
technology allowing network man-
agers to build affordable network
cores with exceptional performance
and flexibility.
With XRN technology, multiple inter-
connected Gigabit switches behave as
a single distributed switching fabric
that grows with the network, without
the physical limitations of a central-
ized core device.
XRN technology, enabled via the XRN
Interconnect Kit, is supported on the
3Com Switch 4050 and Switch 4060,
and the SuperStack 3 Switch 4900
family.

The 3Com Switch 4050 and Switch
4060, based on a 3Com-developed
ASIC architecture, deliver 56 Gbps
multilayer switching capacity for
bandwidth-intensive core backbones
and demanding enterprise applica-
tions. Each switch delivers
non-blocking Layer 2 and Layer 3
switching across all ports, forwarding
at speeds in excess of 40 Mpps.
Many Gigabit backbones require mul-
timode and single mode fiber for
connectivity to distributed wiring
closets or buildings, and copper
cabling for high bandwidth connec-
tions to servers and hosts in the data
center.
The 3Com Switch 4050 and Switch
4060 deliver integrated media flexibil-
ity by providing different
combinations of 1000BASE-SX and
10/100/1000 ports, and six GBIC ports
(normally used for campus backbone
connectivity).
In addition, using link aggregation,
these switches can be connected to an
external server farm aggregation
device such as the 3Com SuperStack 3
Switch 4924. An optional expansion
slot accommodates a 4-port Gigabit
module for even greater flexibility.
