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 Translation of NetBios functional address from
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.
