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.
