master | slave auto SPEED-LIST rj45 sfp DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Specifies the port operates as master or slave timing. This parameter is only applicable to 10GBASE-T connections. Specifies that for copper ports, it specifies to determine the speed and flow control via auto-negotiation with its link partner. Specifies that for fiber ports (1000BASE-SX/LX), it enables the auto-negotiation option. Auto-negotiation will start to negotiate the clock and flow control with its link partner. (Optional) Specifies a list of speeds that the Switch will only auto-negotiate to. The speed can be 1000, and/or 10giga. Use a comma (,) to separate multiple speeds. If the speed list is not specified, all speed will be advertised. (Optional) Specifies to configure speed for RJ45 media. For combo ports, if RJ45 or SFP/SFP+ is not specified, RJ45 is used. (Optional) Specifies to configure speed for SFP/SFP+ media. Default The speed is automatic for 100BASE-TX, 1000BASE-T and 10GBASE-T interfaces. The speed is fixed to 100Mbps for 100BASE-FX interfaces. The speed is fixed to 1000Mbps for 1000BASE-SX/LX interfaces. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline If the specified speed is not supported by the hardware, error messages will be returned. For the 100BASE-FX modules, the speed is always fixed at 100Mbps, full duplex, and no-negotiation. No command can change the settings. For the 1000BASE-SX/LX modules, the speed is always fixed to 1000Mbps and full duplex, and only the speed 1000 and speed auto commands are valid. For a 1000BASE-T connection, if the speed is specified to 1000Mbps, the port must be configured as master or slave. For a 10GBASE-T connection, if the speed is specified to 10Gbps, the port must be configured as master or slave. Auto-negotiation will be enabled if either the speed parameter is set to auto, or the duplex parameter is set to auto. If the speed parameter is set to auto, and the duplex parameter is set to the fixed mode. Only the speed will be negotiated. The advertised capability will be configured to the duplex mode combined with all the possible speeds. If the speed is to set to a fixed speed and duplex is set to auto, only the duplex mode is negotiated. For 10GBASE-R connections, if auto-negotiation is enabled, the system will automatically configure the speed (1000M or 10G) according to the type of SFP/SFP+. Example This example shows how to configure ethernet 1/0/1 to only auto-negotiate to 10Mbps or 100Mbps.
