The following parameters can be configured:
Parameter Description
From…. To Use the pull-down menus to select the port or range of ports to be configured.
State Toggle this field to either 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
Auto, 10M/Half, 10M/Full, 100M/Half and 100M/Full, 1000M/Full_M and 1000M/Full_S. There
is no automatic adjustment of port settings with any option other than Auto.
The Switch allows the user to configure two types of gigabit connections; 1000M/Full_M and
1000M/Full_S. Gigabit connections only support full duplex connections and take on certain
characteristics that are different from the other choices listed.
The 1000M/Full_M (master) and 1000M/Full_S (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_M) 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_S) uses loop timing, where the timing comes form a data stream received from
the master. If one connection is set for 1000M/Full_M, the other side of the connection must
be set for 1000M/Full_S. Any other configuration will result in a link down status for both
ports.
Flow Control Displays the flow control status used for the various port configurations. Ports configured for
full-duplex use 802.3x flow control, half-duplex ports use backpressure flow control, and Auto
ports use an automatic selection of the two. The default is Disabled.
Medium Type This applies only to the Combo ports. If configuring the Combo ports this defines the type of
transport medium used. SFP ports should be set at Fiber and the Combo 1000BASE-T ports
should be set at Copper.
Click Apply to implement the new settings on the Switch.
Port Description
The Switch supports a port description feature where the user may name various ports on the Switch. To assign
names to various ports, click Administration > Port Configuration > Port Description to view the following
window:
Use the From and To pull-down menu to choose a port or range of ports to describe, and then enter a description
of the port(s). Click Apply to set the descriptions in the Port Description Table.
The Medium Type applies only to the Combo ports. If configuring the Combo ports this defines the type of tranport
medium used. SFP ports should be nominated Fiber and the Combo 1000BASE-T ports should be nominated Copper.
The result will be displayed in the appropriate switch port number slot (C for copper ports and F for fiber ports).
