SWITCH 40x0 FAMILY DATA SHEET
High Availability
Without Compromise
3Com Gigabit Multilayer Switching
software, supported by the switches in
the 3Com Switch 40x0 family, provides
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, Switch 4060,
and Switch 4070 support four priority
queues per port, Weighted Round
Robin queue scheduling, traffic clas-
sification and prioritization based on
Layer 2 (physical 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,
Switch 4060, and Switch 4070 enable
automatic redirection of web traffic to
3Com SuperStack 3 Webcache appli-
ances, enhancing web performance.
These switches provide enhanced
device management functionality
through support for BootP/DHCP
clients, seven groups of RMON, and
RMON event notification via an inte-
grated SMTP client.

Advanced Multilayer
Switching Functionality
"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
High availability is one of the key
requirements for connectivity in the
core backbone of enterprise networks.
The switches in the 3Com Switch
40x0 Family (Switch 4050, Switch
4060, and Switch 4070) deliver this
capability through a combination of
hardware and software features that
provide redundancy, reliability, ser-
viceability, and high network-level
availability without compromising
performance or functionality.
These switches support two redundant,
load sharing and hot-swappable
power supplies in addition to hot-
swappable fan trays and GBIC and
SFP transceivers.
Network-level availability features
such as Link Aggregation and Rapid
Spanning Tree enable resilient data
paths across the network for even
greater fault tolerance.
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, Switch 4060,
Switch 4070, and the SuperStack 3
Switch 4900 family.
