Setting a Port’s Speed and Duplex Mode
To set the speed and duplex mode on the port, perform the following
procedure:
1. From the main menu, select Physical Interface.
The Physical Interface page is shown in Figure 9 on page 34.
2. In the Port List, select the port you want to configure, or scroll through
the list below.
The port is highlighted in the port list.
3. In the Mode list, select one of the following combinations of port speed
and duplex mode:
Auto - The port uses Auto-Negotiation to set its speed and duplex
mode. This is the default setting for all ports.
10M-Half - 10 Mbps, half-duplex
10M-Full - 10 Mbps, full-duplex
100M-Half - 100 Mbps, half-duplex
100M-Full - 100 Mbps, full-duplex
1G-Full - 1 Gbps, full-duplex.
When a twisted pair port on the switch is set to Auto-Negotiation, the
default setting, the end node should also be using 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 mismatch if the end node
is operating at a fixed duplex mode of full-duplex. To avoid this
problem when connecting an end node with a fixed duplex mode of
full-duplex to a switch port, disable Auto-Negotiation on the port and
set the port’s speed and duplex mode manually.
4. Click Modify.
The mode setting shown in the table for that port is changed. Continue
to select and modify other ports as necessary.
5. Do one of the following:
ˆ Click OK to save the changes.
ˆ Click Reload to clear the setting and start over.
