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 highvolume servers placed on dedicated full-duplex segments and having client workstations placed on shared segments 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 forwarding 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:

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 highspeed Token Ring,ATM or the IBM 8260 Nways Multiprotocol Switching Hub.

Available UFCs include:

4-Port Token-Ring Enhanced UTP/STP

2-Port Token-Ring Enhanced Fiber

1-Port ATM Token-Ring II MMF

MMS Client MMF

MSS Client SMF

MSS Domain Client

Chassis-based for flexibility

Universal Feature Card slots allow you to build a wide variety of switched network configurations using the broad set of optional feature cards that are shared between both models. This set of features provides copper and fiber Token-Ring ports, high-speed uplinks and Multiprotocol Switched Services (MSS) Client support.This expands the capabilities of the 8270 with a sophisticated set of VLAN, filtering and Layer 3 switching functions. Unrestricted by a fixed-port configuration, the UFCs can be used in each of the slots of the IBM 8270 to construct a wide variety of switched networks.

High-speed forwarding

When configured with the appropriate number of Token-Ring Universal Feature Cards, the 8270 provides high-speed forwarding of Token-Ring frames among shared or dedicated Token-Ring LAN segments. Similar in function to a multiport bridge, the 8270 forwards Token-Ring frames from one port to another, based on Token-Ring MAC addresses. The 8270 creates multiple, parallel paths among the connected Token-Ring LAN segments and devices.

Supports full-duplex communication

The 8270 supports full-duplex communication with LAN stations equipped with full-duplex Token-Ring adapters. Fullduplex Token-Ring connections can provide up to twice the bandwidth (up to 32 Mbps) of standard half-duplex connections.

Added capacity and flexibility

With the 8270 you get added capacity and flexibility at a low cost per port.

The LAN shown in Figure 1 has provided excellent service in this data environment. But growth and new graphics applications are causing performance problems on this traditional, shared- media,16-Mbps LAN.

Combining switching, full-duplex- attached servers and micro-segmented, shared-media LANs (Figure 2) gives the following advantages:

• No change to installed adapters

• No change to house wiring

• No change to application software

• Fewer users per segment

• More bandwidth per user

• Reduction in the number of bridges

• Reduced complexity

• Reduced cost

8270 Nways LAN Switch Family Model 800

Backbones remain overburdened by

demands of e-mail, busy servers and Figure 3. Backbone congestion Internet traffic (see Figure 3). Until now

all you could do was install a faster, shared-media LAN like FDDI.

The 8270 Model 800 can act as a powerful workgroup switch or replace the entire backbone with a single switch (see Figure 4). Use TokenPipes to double or quadruple the bandwidth if you need it. TokenPipe allows you to connect up to four parallel, 32-Mbps paths between any two Token-Ring switches, providing as much capacity between switches as you need. This solution means:

• No change to application software

• Elimination or reduction of bridges

• Elimination of all routers except those on the periphery

• Scalable bandwidth between switches using TokenPipes

• Simplified network management

Network and device management

A full console interface, accessible using either a Telnet interface or the serial port (VT-100 or VT-100 emulator) on the front panel, can be used to configure and monitor the IBM 8270. Alternatively, the IBM 8270 contains a management agent that allows you to monitor and control its operation from SNMP applications. IBM’s suite of network management applications, such as the IBM Nways Workgroup Manager for Windows NT and the IBM Nways Manager for AIX, allow you to manage your IBM 8270 using a rich set of graphical interfaces from a central location.

Further, when and if new functions or problem fixes become available, the IBM 8270 can be easily upgraded with new operational code. These software updates will be made available via the World Wide Web, allowing you to conveniently upgrade the operation of your IBM 8270.

With the IBM 8270’s TokenProbe support, you can designate one of the Token-Ring ports to mirror the traffic on another Token-Ring port. This allows you to tune or troubleshoot any of the Token-Ring ports on your switch using an external protocol analyzer. The IBM 8270 SNMP agent also includes remote monitoring (RMON) support that allows you to monitor network conditions on all LAN segments attached to your 8270 simultaneously and to report this information to an RMON application using industry-standard protocols.

Model Comparison

Though functionally comparable, the differences between the IBM 8270 Model 600 and the current Model 800 are summarized in the following table:

Except for considerations pertaining to their number of feature slots and redundancy characteristics, the IBM 8270 Model 600 is suitable for use in the same environments as the Model 800. However, with different redundancy characteristics, the 8270 Model 600 may be better placed closer to the edge rather than the center of your network.
