Note

Auto Speed/Duplex is disabled when you manually configure a port’s Speed/Duplex. In this situation, you must use a crossover Ethernet cable to connect that port to another network device.

2.To set the parameters for a port, choose the port using the From and To lists. You can select one port (From 2 To 2, for example) or a range of ports (From 1 To 5, for example).

3.From the State list, choose one of the following:

Enabled

The port is enabled. This is the default.

Disabled

The port is disabled.

4.From the Speed/Duplex list, select one of the following:

ˆAuto - When you select this option, the switch automatically sets the speed and duplex mode of the port. The switch determines the highest possible common speed between the port and its end node, and sets the port to that setting. This helps ensure that the port and its end node are operating at the highest possible speed.

In order for a switch port to successfully autonegotiate its duplex mode with an end node, the end node should also be using autonegotiation. Otherwise, a duplex mode mismatch can occur. A switch port using autonegotiation defaults to half-duplex if it detects that the end node is not using autonegotiation. This results in a mismatch if the end node is operating at a fixed duplex mode of full-duplex.

To avoid this problem on the copper ports, when you connect an end node with a fixed duplex mode of full-duplex to a switch port, you should disable autonegotiation on the port and set the port’s speed and duplex mode manually.

If you think that a port and end node are not operating in the same duplex mode at a speed of 1000Mbps, you can configure the ports for Forced mode. To do this, you configure the switch port to be the master port (capable of sending detect and negotiate signals), and the end node as a slave port (capable of receiving negotiate signals).

Note

You cannot modify the speed or duplex mode of the SFP ports.
