Fully configurable Token-Ring LAN switch at a
competitive cost
IBM 8270 Nways LAN Switch Family
Highlights
• Flexible enough to meet your
exact needs
• Layer 3 switching
• Multiprotocol support
• Full-duplex (bi-directional)
communication
• ATM uplinks
• Three new MSS Universal Feature
Cards
New model
A new member has been added to the
IBM 8270 Nways
®
LAN Switch family of
Token-Ring LAN switches. The new
Model 600 joins the Model 800, providing
a smaller, entry configuration (six slots).
Both models allow flexible configuration
with rich functionality provided by the
common set of Universal Feature Cards
they share. Similar to the Model 800, a
typical network would benefit from the
Model 600 by having each of its high-
volume servers placed on dedicated
full-duplex segments and having client
workstations placed on shared seg-
ments using standard Token-Ring
concentrators such as the IBM 8239
Token-Ring Hub.
New features
Two new UFCs extend MSS forwarding
and routing services to the 8270 Nways
LAN Switch Family. Both the MSS Client
and MSS Domain Client Universal
Feature Cards (UFCs) provide forward-
ing and routing services. The MSS Client
also has an integrated ATM port and
provides ATM-to-LAN port bridging.
These client-function products complete
the MSS client/server family and allow
the MSS Server products to perform their
job in the network at maximum efficiency.
Along with virtual LAN (VLAN) support by
protocol, OSI Layer 2 and 3 forwarding of
IP, IPX, AppleTalk and Banyan VINES
protocols are provided.
Cost-effective Token-Ring
switching
The IBM 8270 Nways Token-Ring LAN
Switch provides a cost-effective solution
to Token-Ring LAN performance
requirements. With a minimum of
disruption to existing networks, you can
significantly address LAN performance.
A powerful LAN switch
With the 8270 you can build large
switched networks with high-speed
uplinks. A redundant power supply is
available to help ensure continuous
operation.
You can configure the versatile, modular
8270 LAN switch to:
• Add from 4 to 30 ports to your network
configuration, more ports per switch than
any other model.
• Install uplink UFCs to connect native
protocols to high-speed links like high-
speed Token Ring, ATM or the IBM 8260
Nways Multiprotocol Switching Hub.
