Features
The IBM 8276 Nways
RoutePort provides a 36-port Ethernet
port switching concentrator that
complements IBM’s powerful 8273 and
8274 Nways RouteSwitches and 8271
Nways LAN Switches. Used in combination 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 providing 10 Mbps to every desktop.
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.

Powerful VLAN extension
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.
Reducing current and
future costs
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.
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 management for improved network performance
and user response.
Integrated network management
The 8276 is equipped with a built-in
SNMP agent that allows the hub to be
managed through the IBM RouteSwitch
Network Manager and RouteTracker
Manager. And the 8276 supports
network management and control via a
console management terminal connected to the serial communications
port.
IBM Nways RouteSwitch
Network Manager
IBM’s Nways RouteSwitch Network
Manager provides what you need in a
network management package.
Replace guesswork or calculations with
real-time, graphical representations of
network performance, alarms and
configurations. Network configuration,
monitoring and diagnostic information is
simple, regardless of the mix of different
vendor equipment that makes up your
network. You can integrate the
RouteSwitch Network Manager with a
variety of network platforms including HP
OpenView for Windows
for UNIX
®
, SunSoft SunNet Manager and,
of course, IBM’s NetView
®
, HP OpenView
®
for AIX®.
IBM Nways RouteTracker
Manager
A powerful graphical application, the
RouteTracker provides the flexibility of
policy-based VLANs with the security
and isolation of port VLANs using
RouteTracker grouping capability. You
can view the relationship between
groups, VLANs and devices across the
entire network. Drag-and-drop features
with smart wizards make VLAN setup and
maintenance easy.
Technical details
The 8276 provides thirty-six 10BASE-T
Eth erne t po rts. Two of these ports,
depending on the 8276 model, may be
configured as 10BASE-FL using singlemode or multimode cabling. The
10BASE-T ports connect through RJ-45
connectors using a maximum of 100 m
(328 ft) of 100-ohm STP or UTP cable. The
optional, 10BASE-FL por ts connect
through SC (single-mode) or ST (multimode) connectors using a maximum of
2000 m (6562 ft) of fiber cable.
There is one EIA 232-C serial port that
connects through a 9-pin, D-shell
connector to an optional customerprovided management console.
