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 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.
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.
