DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide 122. Switch Port Commands 122-1 duplex This command is used to configure the physical port interface's duplex setting. Use the no form of this command to revert to the default settings. duplex {full | auto} [rj45 | sfp] no duplex [rj45 | sfp] Parameters full auto rj45 sfp Specifies that the port operates in the full-duplex mode. Specifies that the port's duplex mode will be determined by auto-negotiation. (Optional) Specifies to configure the duplex for RJ45 media. For combo ports, if RJ45 or SFP is not specified, RJ45 is implied. (Optional) Specifies to configure the duplex for SFP media. Default The duplex mode will be set as automatic for 100BASE-TX and 1000BASE-T interfaces. The duplex mode will be set as full for 100BASE-FX and 1000BASE-SX/LX interfaces. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline 100BASE-FX is always set at the speed of 10 Mbps and full-duplex. 1000BASE-SX/LX is always set at the speed of 100 Mbps and full-duplex. For 100BASE-FX and 1000BASE-SX/LX modules, this command cannot take effect. 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. The half-duplex mode is not supported on the Switch. Example This example shows how to configure port 1 to operate at a forced speed of 100Mbits and specifies that the duplex mode should be set to auto-negotiated. Switch# configure terminal Switch(config)# interface eth1/0/1 Switch(config-if)# speed 100 Switch(config-if)# duplex auto Switch(config-if)# 1535
