3 Switch 4900s or
Switch 4900 SXs, scaling the backbone
to 24 wirespeed Gigabit Layer 3
switching ports.
Performance
Wirespeed, non-blocking Gigabit Ethernet
switching across all ports delivers maxi-
mum performance for heavily utilized
networks.
The use of XRN Technology
intelligent forwarding can scale the
performance of two units to 48 Gbps
.
Affordability
The SuperStack 3 Switch 4900 family of
fixed configuration managed switches
provides unmatched value and industry
leading performance without compromise,
enhanced further with the pay-as-you-
grow capabilities of XRN technology.
High Availability
Robust availability features include
link aggregation, support for Rapid
Spanning Tree, Redundant Power
Supply system, and e-mail or pager
status notification, ensuring maximum
uptime for critical applications.
Prioritize Business Critical Traffic
Advanced Class of Service support
including support for four queues per
port, 802.1p, and multilayer packet
classification capabilities to allow
prioritization of critical traffic.
Layer 3 Switching
Layer 3 switching capabilities such as
support for IP unicast routing using
static routes, OSPF
*
, RIP/RIPv2, CIDR,
and UDP Helper, enhance perfor-
mance, provide network control and
security, and enable logical network seg-
mentation.
Advanced Security Capabilities
Security features such as RADIUS client
support and Routed Access Control
Lists ensure authorized user access to
network resources.
Powerful Management
3Com Network Supervisor application
(trial copy included) with discovery,
mapping, monitoring, and alerting for
easy network administration. Intuitive
interface speeds network-wide set-up of
switch traffic prioritization.
The 3Com SuperStack 3 Switch 4900
delivers high performance, feature-rich
Gigabit Ethernet switching in a simple,
affordable platform, making it an excel-
lent solution for small-to-medium-size
networks with growing bandwidth
requirements. It’s also perfect for large
enterprises that require low cost yet high
functionality Gigabit Ethernet switching
across their data center and the server
farm or wiring closet.
Both switches support 3Com Gigabit
Multilayer Switching (GMS) software,
offering advanced Layer 2 switching
features such as traffic prioritization,
VLANs, multicast filtering, and RMON,
as well as Layer 3 switching features,
including support for unicast IP routing
supporting static routes, RIP/RIP2 and
OSPF* and Access Control Lists. Their
Class of Service capabilities are ideal for
key business applications, such as mul-
timedia, LAN telephony, database and
inventory/purchase applications.
