Extending switching benefits to the user’s desktop

Highlights
The IBM 8276 Nways™ Ethernet
Users connected to an 8273 or 8274
through the 8276 inherit the benefits of
their powerful VLAN implementation. The
8276 can support up to 32 policy-based
VLANs on a single segment. A single
VLAN can span multiple segments.
RoutePort provides a 36-port Ethernet
port switching concentrator that
• Flexible-port switching concen-
trator
complements IBM’s powerful 8273 and
8274 Nways RouteSwitches and 8271
Nways LAN Switches. Used in combina-
tion with one of these switches, the 8276
extends the benefits of switching to the
user’s desktop. It’s a good solution for
customers who want the advantages of
switching, LAN segmentation, virtual
LANs (VLANs), routing and increased
bandwidth but who can’t justify the cost
of providing10 Mbps to every desktop.

Reducing current and
futurecosts
LAN equipment and administration costs
are major expenses when expanding
networks. Per-port costs are of particular
concern for both current and future
needs. Use of the 8276 with one of IBM’s
powerful LAN switches maximizes user
function at minimum port cost and allows
for future expansion at minimum
additional cost.
• Easy administration with power-
ful, graphicalmanagementtools
• Simple configuration
The 8276 allows all of its ports to be
divided via software into as many as four
independent Ethernet segments,
providing an effective bandwidth of
40 Mbps. And depending on your model
selection, up to two of the 36 ports on
each 8276 can be configured as optical
fiber links.
• CompatiblewithotherIBM

Simplified changes
The ability to dynamically add, delete or
move users and make other network
changes through software means that
administrators can reconfigure the
network without cable changes or
network downtime. Being able to easily
move users from one segment to another
provides simple bandwidth manage-
ment for improved network performance
and user response.

Software allows the 8276 to be config-
ured internally as one to four indepen-
dent Ethernet segments. Any or all of the
36 Ethernet ports can be assigned to any
of the four segments. These assignments
can be altered via software at any time,
without affecting uninvolved ports.
