DGS-3130 Series Layer 3 Stackable Managed Switch Web UI Reference Guide Parameter Description Options to choose from are Auto, 10M, 100M, 1000M, 1000M Master, 1000M Slave, and 10G. The Master setting 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 uses loop timing, where the timing comes from a data stream received from the master. If one connection is set for master, the other side of the connection must be set for slave. Any other configuration will result in a 'link down' status for both ports.  Auto - Specifies that for copper ports, auto-negotiation will start to negotiate the speed and flow control with its link partner. For fiber ports, auto-negotiation will start to negotiate the clock and flow control with its link partner.  10M - Specifies to force the port speed to 10Mbps. This option is only available for 10Mbps copper connections.  100M - Specifies to force the port speed to 100Mbps. This option is only available for 100Mbps copper connections.  1000M - Specifies to force the port speed to 1Gbps. This option is only available for 1Gbps fiber connections.  1000M Master - Specifies to force the port speed to 1Gbps and operates as the master, to facilitate the timing of transmit and receive operations. This option is only available for 1Gbps copper connections.  1000M Slave - Specifies to force the port speed to 1Gbps and operates as the slave, to facilitate the timing of transmit and receive operations. This option is only available for 1Gbps copper connections.  10G - Specifies to force the port speed to 10Gbps. This option is only available for 10Gbps copper or fiber connections. Capability Advertised Description When the Speed is set to Auto, these capabilities are advertised during autonegotiation. Enter a description for the corresponding port here.
