SSIM-H2-02 Fast Ethernet - Translational Switch SmartStack Interface Module Installation and User Guide Introduction
1. Introduction
The Cabletron Systems SmartStack SSIM-H2-02 2-port Translational Switch
SSIM (SmartStack SSIM-H2-02) provides connectivity to 10/100 Mbps Fast
Ethernet for the SmartStack STS16-20RM Token Ring Switch. Designed for high
performance and low latency, the SmartStack SSIM-H2-02 seamlessly integrates
legacy Token Ring networks and Fast Ethernet backbones.
➽Note: References to SmartStack STS16-20RM are also applicable to SmartStack
STS16-20FRM.
The module mounts in one of the two front panel expansion module slots on the
SmartStack STS16-20RM switch.
Figure 1. SSIM-H2-02 Switch SmartStack Interface Module
The SSIM-H2-02 conforms to the IEEE standard 802.3U for 100 Mbps Fast
Ethernet 100BASE-TX.
A Translational Switch (TS) port can connect to a standard Fast Ethernet adapter or
it can act as a trunk port and carry traffic from all of the 63 VLANs it is possible to
configure inthe switch. This is achieved usingstandard IEEE 802.1QVLAN frame
tagging. For each VLAN, a virtual port is created which behaves much like an
ordinary Ethernet port.
The module supports all of the switching modes implemented in the switch. Eight
LEDs on the front panel indicate the overall operationalstate of the module and the
two ports. Configuration and detailed status information is available from the
switch console or from the graphical management application.

SSIM-H2-02 Fast Ethernet - Translational Switch SmartStack Interface Module Installation and User Guide Introduction
The module supports translational switching for all key network protocols (such as
IP, IPX, SNA, NetBios) and generic conversion:
Feature Description
SRT and SRB Support for SRT and SRB bridging.
IEEE 802.1Q This standard frame-tagging protocol is used
to carry frames that belong to different
VLANs over the same physical Fast Ethernet
link.
Benefit: Enables VLAN trunking with other
standards based equipment.
IEEE 802.1D IEEE 802.1D Spanning Tree on the Ethernet
side with a manual configuration option.
IP multicasts address
translation IP multicasts translated to a single functional address on the Token-Ring side, and IP
multicasts on the Token-Ring side translated to
multiple MAC addresses on the Ethernet side.
IP fragmentation IP fragmentation makes it possible to easily
connect IP networks between Token-Ring and
Ethernet networks.
NetBios addresses
translation Translationof NetBiosfunctionaladdressfrom the Token-Ring side to a specific Ethernet
group address, and frames with an additional
functional addresses from Token-Ring side are
not forwarded on the Ethernet side.
Source-Routing Source-Routing is supported.
Benefit: Provides optimal Token-Ring
connectivity and ensures smooth integration
into existing Source-Routing based networks.
For each supported protocol, frames can be
sent as transparent or source-routed traffic.
Table 1. Features and Benefits

3
SSIM-H2-02 Fast Ethernet - Translational Switch SmartStack Interface Module Installation and User Guide Introduction
SNMP SNMP is supported via the host processor (the
processor on the SmartStack STS16-20RM).
This makes it possible to configure the device
in a standards-based way and as an integrated
part of the LAN switch.
Can serve multiple
switches in one stack The SmartStack SSIM-H2-02 can serve as uplink for multiple LAN switches
interconnected by a stacker. This reduces the
cost of connecting a number of LAN switches
to an Fast Ethernet backbone.
Dual home FEP A Token-Ring network using SRB can support
duplicate MAC addresses. This capability has
been exploited by SNA gateways, which can
provide a redundant host connection: two
gateways have the same MAC address but are
on different rings and due to the source routing
discovery process the SNA sessions are
randomly distributed between the two
gateways. Sessions are established between
configured MAC addresses.
Protocol filters The SmartStack SSIM-H2-02 offers the same
protocol filters as the SmartStack STS16-
20RM. This makes for consistent protocol
filtering and thereby reduces the risk of
network congestion and security breaches.
Broadcast Suppression On output, the Translational Switch SSIM
must keep the rate of broadcast frames sent to
Ethernet within the limit set by the Maximum
Broadcast Frame Count per Second
configuration parameter. Broadcasts include:
- ARE, STE source routed frames
- unknown destination frames
- frames with the MAC header broadcast bit set
