Figure 2 - 7. Port Settings window
The following parameters may be configured or viewed:
Parameter Description
From Port / To Port
Use the drop-down menus to select the ports to be configured.
State
Use the drop-down menu to enable or disable a given port or group of ports.
Speed/Duplex
Toggle the Speed/Duplex field to either select the speed and duplex/half-duplex state of the
port. Auto denotes auto-negotiation between 10 and 100 Mbps devices, in full- or half-
duplex. The Auto setting allows the port to automatically determine the fastest settings the
device the port is connected to can handle, and then to use those settings. The other
options are 10M Half, 10M Full, 100M Half, 100M Full, 1000M Full_Master, 1000M
Full_Slave, and 1000M Full. There is no automatic adjustment of port settings with any
option other than Auto.
The Switch allows the user to configure three types of gigabit connections; 1000M
Full_Master, 1000M Full_Slave, and 1000M Full. Gigabit connections only support full
duplex connections and take on certain characteristics that are different from the other
choices listed.
The 1000M Full_Master and 1000M Full_Slave parameters refer to connections running a
1000BASE-T cable for connection between the Switch port and other device capable of a
gigabit connection. The master setting (1000M Full_Master) will allow the port to advertise
capabilities related to duplex, speed and physical layer type. The master setting will also
determine the master and slave relationship between the two connected physical layers.
This relationship is necessary for establishing the timing control between the two physical
layers. The timing control is set on a master physical layer by a local source. The slave
setting (1000M Full_Slave) uses loop timing, where the timing comes from a data stream
received from the master. If one connection is set for 1000M Full_Master, the other side of
the connection must be set for 1000M Full_Slave. Any other configuration will result in a link
down status for both ports.
