Ports set in the 100Tx/Full state are set to work at 100 Mbps full duplex.

Ports set in the 10Tx/Half state are set to work at 10 Mbps half duplex.

Ports set in the 10Tx/Full state are set to work at 10 Mbps full duplex.

The 100BASE-FX ports can only be in the 100/Fx Half or 100/Fx Full states. The default setting is half duplex. The 1000BASE-SX port can only be in 1000SX/Full. Half-duplex operation is not supported.

Port State

All ports have four states: blocking, listening, learning and forwarding. Blocking means that nothing is coming through the port. If the Spanning Tree Algorithm detects a loop it will change the state of the port where the loop is detected to the Blocking State. You can disable the Spanning Tree Algorithm. Forwarding means the port is forwarding data packets to their destination. Listening means that the port is listening for data packets. Learning means the port is learning the MAC address for data packets. This setting cannot be manually changed.

Priority

The port priority can be set from zero to 255. Zero is the highest port priority. The port assigned a zero will be the root port. The default setting will work in most situations.

Flow Control

The 1000BASE-SX module allows you to enable or disable flow control. Flow control allows the module to stop the flow of information from another device.

Follow these steps to change the port state:

1.Select the State setting of the appropriate port.

2.Toggle the space bar to change the current setting.

3.Select Save and press Enter.

Follow these steps to change a port’s physical state:

1.Select the physical setting of the appropriate port.

2.Toggle the space bar until you find the appropriate setting.

3.Select Save and press Enter.

Follow these steps to change the port priority:

1.Select the priority of the appropriate port.

2.Enter a new value between zero and 255.

3.Select Save and press Enter.

Follow these steps to enable or disable flow control:

1. Toggle the space bar to change the setting, select Save and press Enter to save changes.
