3COM®SWITCH 4050 AND SWITCH 4060 DATA SHEET
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.
