Ethernet Workgroup Devices
The following sections describe the various Cabletron Systems networking
devices that may be used in an Ethernet workgroup implementation. These
Ethernet devices are divided into two categories - shared Ethernet devices and
switched Ethernet devices. Shared Ethernet devices are those which connect all
stations and links to a single Ethernet collision domain. The switched devices
provided a number of dedicated Ethernet collision domains and provide for
discriminatory connections between those interfaces.
Shared Devices
There are several Cabletron Systems networking devices to consider when
designing an Ethernet workgroup that will share a single Ethernet network
segment. The available devices are listed in Table 6-1, below.
The columns in Table 6-1 indicate some of the most important data to be
considered when selecting networking devices for a particular workgroup
implementation. The meanings of these fields and their various values are
described below.
a. These products can be managed through the addition of an intelligent stackable device to their stack.
