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
