CrossFire 8730 Switch Reference Guide, DOC-7047 v. 1.1 Introduction
Translation from Token-Ring to Fast Ethernet
The configuration options of the CrossFire 8730 Switch provide for several
translation strategies, thereby providing extra flexibility for managers when
designing their integrated network. The best option will depend on the current
network and the migration strategy.
This section describes a typical migration strategy and gives an example of an
application of the CrossFire 8730.
Isolated Ethernet Segments or Servers
As the starting point for migrating a bridged Token-Ring network to Fast Ethernet,
the switch could be set up with the four Fast Ethernet ports connected to four
isolated Ethernet segments or Fast Ethernet Attached servers. The CrossFire 8730
Switch will make servers and workstations attached to the Fast Ethernet ports
appear to be on a single logical Ethernet segment connected to the Token-Ring
network through the switch. This configuration will provide a translation
bandwidth corresponding to that of four Fast Ethernet ports.
