xStack® DGS-3200 Series Layer 2 Gigabit Ethernet Managed Switch Port Configuration The Port Configuration folder contains three windows: Port Settings, Port Description, and Port Error Disabled. Port Settings To view the following window, click Configuration > Port Configuration > Port Settings: Figure 2- 9. Port Settings window To configure switch ports: 1. Choose the port or sequential range of ports using the From Port and To Port pull-down menus. 2. Use the remaining pull-down menus to configure the parameters described below: The following parameters may be configured or viewed: Parameter Description State Toggle the State 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 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. Flow Control Displays the flow control scheme used for the various port configurations. Ports configured for full-duplex use 802.3x flow control, half-duplex ports use backpressure flow conٛ onfi, and Auto ports use an automatic selection of the two. The default is Disabled. 11
