Ports in the Auto state automatically negotiate speed and duplex mode. This is the
default setting.
Ports set in the 1000SX/Full physical state are set to work at 1000 Mbps Full
Duplex.
Ports set in the 100TX/Half physical state are set to work at 100 Mbps half duplex.
Ports set in the 100TX/Full state are set to work at 100 Mbps full duplex.
Ports set in the 10T/ Half state are set to work at 10 Mbps half duplex.
Ports set in the 10T/Full state are set to work at 10 Mpbs full duplex.
The 100BASE-FX ports can only be in the 100/ Half or 100/Full states. 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 changed manually.
Priority
The port priority can be set from zero to 255. Zero is the highest port priority. The
default setting will work in most situations.
Link Status
The Link Status shows whether the link is active and displays the speed and
duplex mode of active ports.
Follow these steps to change the port state:

Link Down indicates the port is not active
10T/Half indicates the link is connected at 10 Mbps half duplex
10T/Full indicates the link is connected at 10 Mbps full duplex
100X/Half indicates the link is connected at 100 Mbps half duplex
100X/Full indicates the link is connected at 100 Mbps full duplex
1000SX Full Duplex indicates the link is connected at 1000 Mbps
