Hardware Installation and Network Topology
CHAPTER 1
Configuration guidelines:
Servers or workstations: Configure servers or workstations
directly connected to the switch for full duplex. Since the traffic is
two-way traffic, you’ll see a performance increase with a full
duplex configuration. See page 22 for instructions on configuring
full duplex.
Security considerations: If you have concerns about server
access or other security issues, configure security virtual LANs
(SVLANs) to prevent segments (ports) from accessing other ports.
In the example on the previous page, you may want to prevent
workstations on the 10 Mbps hub on port 4 from accessing the file
server on port 2. See page 23 for more information on configuring
SVLANs.
100 Mbps or 10 Mbps hubs: Leave hubs (repeaters) at half
duplex with flow control enabled. Since hubs broadcast traffic
among all ports and full duplex requires a point-to-point
connection, you can’t configure a 10 or 100 Mbps hub for full
duplex.
