Network Configurations - Nortel BayStack 450-24T Using Manual

Using the BayStack 450 10/100/1000 Series Switch
Autosensing is used when the attached device is not capable of autonegotiation or
is using a form of autonegotiation that is not compatible with the IEEE 802.3u
autonegotiation standard. In this case, because it is not possible to sense the
duplex mode of the attached device, the BayStack 450 switch reverts to
half-duplex mode.
When autonegotiation-capable devices are attached to the BayStack 450 switch,
the switch ports negotiate down from 100 Mb/s speed and full-duplex mode until
the attached device acknowledges a supported speed and duplex mode.
For more information about autosensing and autonegotiation modes, see
"Autonegotiation Modes" on page 4-8.

Network Configurations

You can use BayStack 450 switches to connect workstations, personal computers
(PCs), and servers to each other by connecting these devices directly to the switch,
through a shared media hub that is connected to the switch, or by creating a virtual
LAN (VLAN) through the switch. This section provides five network
configuration examples using BayStack 450 switches:

Note: All models of the BayStack 450 switch can be used interchangeably in
the following network configuration examples.
