Port Description Settings

The Switch supports a port description feature where the user may name various ports.
To view the following window, click System Configuration > Port Configuration > Port Description Settings, as
shown below:
and can be connected to a PC NIC using a straight-through cable or a port (in MDI
mode) on another switch through a cross-over cable.
Cross - Select cross for cross cabling. If set to cross state, the port is in MDIX mode, and
can be connected to a port (in MDI mode) on another switch through a straight cable.
If configuring the Combo ports, this defines the type of transport medium to be used.
Specifies to enable or disable the option to automatically downgrade the advertised
speed. This setting has no effect when the port is working in the forced mode.
Use the drop-down menu to select the speed in Auto, 10M Half, 10M Full, 100M Half,
100M Full, 1000M Full_Master, 1000M Full_Slave, and 10G Full. Auto denotes auto-
negotiation among 10, 100, 1000 Mbps devices, in full- or half-duplex (except 1000 Mbps
and 10Gbps which are always full-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 10G Full option specifies to set the SFP+ port speed to 10Gbps full-duplex.
The Switch allows the user to configure two types of gigabit connections; 1000M
Full_Master, and 1000M Full_Slave which 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.
When the Speed/Duplex is set to Auto, these capabilities are advertised during auto
negotiation.
Use the drop-down menu to specify the auto-negotiation configuration.
Restart An – Select to restart the auto-negotiation process
Remote Fault Advertised - The remote fault advertisement option will be configured.
