NTRODUCTION

The 3Com



Token Ring-in-Fast Ethernet Server network

interface card (3C395 NIC) allows a Fast Ethernet server to

receive encapsulated token ring packets. The 3C395 NIC is

part of a 3Com Token Ring-in-Fast Ethernet (TR-in-FE)

system that allows both Ethernet and token ring clients to

share Fast Ethernet servers without the use of bridging,

routing, or proprietary code.

A basic TR-in-FE system, shown in Figure 1-1, gives token

ring clients access to a 100 Mbps server. Such a system

requires these components:

■ Fast Ethernet switch (SuperStack



II Switch 3000)

■ TR-in-FE server (a Fast Ethernet server with a 3C395 NIC)

■ 3Com SuperStack

II Switch 2000 TR with a 3Com

SuperStack II Switch 2000 TR Token Ring-in-Fast

Ethernet Module (TR-in-FE module)

Figure 1-1 Basic TR-in-FE System

In a basic system, token ring clients connect to a

SuperStack II Switch 2000 TR equipped with a TR-in-FE

module. The TR-in-FE module encapsulates token ring

packets within Fast Ethernet frames and allows

interconnection to a Fast Ethernet switch connected to the

TR-in-FE server. The 3C395 NIC allows the TR-in-FE server to

receive the encapsulated token ring packets, thus providing

access to the 100 Mbps server for token ring clients.
