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.

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 net work components
Full-duplex operation
• Provides up to 32 Mbps, twice the bandwidth of standard half-duplex connections
• Provides for simultaneous, t wo-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
