Setting a Port’s Speed and Duplex Mode
To change a port’s speed or duplex mode, perform the following
procedure:
1. From the Main Menu, type B to select Basic Configuration.
The Basic Switch Configuration Menu is shown in Figure 4 on page 32
2. From the Basic Switch Configuration Menu, type P to select Port
Configuration.
The Port Configuration Menu is shown in Figure 13 on page 54.
3. Type M to select Set Mode.
The following prompt is displayed:
Set Mode -> Enter port number >
4. Enter the number of the port whose speed or duplex mode you want to
change. You can configure only one port at a time.
The following prompt is displayed:
Enter new mode for port n (a/h/H/f/F/T)>
5. Enter the letter that corresponds to the desired speed and duplex
mode setting for the port. The port settings are:
a - Auto: The port uses Auto-Negotiation to set its speed and duplex
mode. This is the default setting for all ports.
h - 10 Mbps, half-duplex
f - 10 Mbps, full-duplex
H - 100 Mbps, half-duplex
F - 100 Mbps, full-duplex
T - 1000 Mbps, full-duplex (uplink ports only)
When selecting a setting, note the following:
ˆ The selections are case sensitive. For example, you must enter a
lowercase letter “a” to select Auto-Negotiation.
ˆ When a twisted pair port on the switch is set to Auto-Negotiation,
the default setting, the end node should also be set to Auto-
Negotiation to prevent a duplex mode mismatch. A switch port
using Auto-Negotiation defaults to half-duplex if it detects that the
end node is not using Auto-Negotiation. This can result in a
