1-3To do… Use the command… RemarksSet the duplex mode duplex { auto | full | half }Optionalauto by default.The optical interface of a Comboport and the electrical interface ofan Ethernet port whose port rateis configured as 1000 Mbps do notsupport the half keyword.Set the transmission rate speed { 10 | 100 | 1000 | auto }OptionalThe optical interface of a Comboport does not support the 10keyword.By default, the port speed is in theauto-negotiation mode.Shut down the Ethernetinterface shutdownOptionalBy default, an Ethernet interfaceis in up state.To bring up an Ethernet interface,use the undo shutdowncommand.10-Gigabit Ethernet ports do not support the duplex command or the speed command.Configuring Flow Control on an Ethernet InterfaceWhen flow control is enabled on both sides, if traffic congestion occurs at the ingress interface, it willsend a Pause frame notifying the egress interface to temporarily suspend the sending of packets. Theegress interface is expected to stop sending any new packet when it receives the Pause frame. In thisway, flow control helps to avoid dropping of packets. Note that this will be possible only after flow controlis enabled on both the ingress and egress interfaces.Follow these steps to enable flow control on an Ethernet interface:To do… Use the command… RemarksEnter system view system-view —Enter Ethernet interface view interface interface-typeinterface-number —Enable flow control flow-control RequiredDisabled by default
