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.

IBM 8270 Nways LAN Switch Family at a glance

Part numbers

LAN ports

• Port number and type depend on which UFCs are installed and on the 8270 model.

 

• Support for 1700 active MAC addresses per port and 10 000 per 8272.

 

 

UFC slots

Model 800: 8 slots

 

Model 600: 6 slots

 

 

Standard compliance

Supports IEEE 802.5 network components

 

 

Full-duplex operation

• Provides up to 32 Mbps, twice the bandwidth of standard half-duplex connections

 

• Provides for simultaneous, two-way transmission between the switch and a LAN station

 

• Improves server throughput by doubling available bandwidth when used on a dedicated

 

LAN segment

 

 

Hardware requirements

Requires at least one Token-Ring Universal Feature Card

 

 

Configuration management

• Console function accessible via Telnet or VT-100 (or VT-100 emulator) connected to serial port

 

• SNMP management for network management platforms capable of accessing SNMP

 

(MIB-II compliant) management agents, such as Nways Workgroup Manager for Windows NT

 

and Nways Manager for AIX®.

 

 

Source-routing technologies

Ease of use with source-route switching

 

Economy with source-route bridging—redundant paths without external hardware

 

 

Interconnectivity

TokenPipe support permits greater LAN segmentation by allowing you to interconnect multiple

 

IBM Nways Token-Ring LAN switches.

 

 

Ease of use

Automatic sensing and configuring of connection types

 

 

Installation

Can be mounted in a standard 19-inch rack or on a flat surface

 

 

Enhanced management tools

Address filters, virtual switch support, and BootP/TFTP TokenProbe port
