• Classical IP Client (RFC 1577). The MSS

Client UFCs can be the entrance point
for LAN IP traffic to ATM Classical IP
networks. The MSS Client UFCs can
connect to multiple different  Logical IP
Subnets (LISs). This support can also
serve as a Classical IP Client ARP
server, eliminating the need for a
separate device for this purpose.
Further, these UFCs can also provide IP
Multicast Client (RFC 1112) support.

• NHRP Client. This function is an

industry standard that allows NHRP
clients to establish a direct ATM
connection. The advantage is that the
default routed path between NHRP
clients can include multiple router
hops. When the NHRP clients develop a
shortcut path, all intermediate router
hops are bypassed.

A maximum of two UFCs from the
following list can be installed in an IBM
8270.

• 1-Port ATM/TR II (FN 2762, PN 86H2762)

• MSS Client MMF (FN 5205, PN

85H4596)

• MSS Client SMF (FN 5206, PN

85H4599)

• MSS Domain Client (FN 5207, PN

85H9303)

There may be usage considerations
associated with some of these combi-
nations.

Benefits

• 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

• Configuration management

 - Console function accessible via

Telnet or VT-100 (or VT-100 emula-
tor) 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-route switching

- Choice of switching modes, including

store-and-forward switching, cut-
through switching and adaptive cut-
through switching

• Source-routing bridging

- Eliminates the need for external

bridges but still offers the benefits of
source routing

•TokenProbe

- Allows a LAN analyzer to be attached

to any copper port for diagnostics or
tuning, even allowing the monitoring
of FDX traffic

• TokenPipe connectivity between

Models 800
- Enables  customers to build configur

ations of more than eight ports

• 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
