•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

asmaller, 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 BanyanVINES protocols are provided.

Cost-effectiveToken-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:

IBM 8270 Nways Token-Ring Switch	IBM 8270 Nways Token-Ring Switch
Model 600	Model 800

•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.
