Introduction
For Enterprise Ethernet networks needing a
scalable, stackable, future-proof Gigabit
Layer 2/3 switching and routing solution,
the 3Com® SuperStack® 3 Switch 3870
24-Port is recommended.
It
is ideal for Gigabit to the desktop applications
in high performance workgroups. As the basis
for a future-proof Enterprise workgroup environment,
with compatibility with slower desktop connections,
it can be the platform to support a gradual
move to Gigabit speeds.
This
24-port 10/100/1000 Gigabit Ethernet switch
combines wirespeed Layer 2 switching and dynamic
Layer 3 routing with stackability up to eight
units high via a 40Gbps stacking architecture
for impressive scalability—to 384 ports
total. Future protection is provided with
108Gbps switching capacity and expansion with
a 10G module slot.
Twenty-four
auto-sensing 10/100/1000 copper ports provide
flexible desktop and workgroup attachments,
which can ease migration for environments
with a mix of 10/100 and Gigabit-enabled desktops
and servers. Four dual-purpose slots support
SFPs that can connect to fiber cabling for
flexible Gigabit Ethernet backbone and server
connections.
Resiliency
features such as IEEE 802.1w Rapid Spanning
Tree, IEEE 802.1s Multiple Spanning Tree,
and IEEE 802.3ad link aggregation across stacked
units help ensure maximum uptime and availability.
Enterprise-class
security features include IEEE 802.1X network
login, RADIUS Authenticated Device Access
(RADA), Auto VLAN Assignment, and Access Control
Lists to manage user access to network resources.
SSH/SSL encrypted device log-in provides secure
remote access for device management.
