Interfaces operating in this mode can send and receive packetssimultaneously.z Half-duplex mode (half). Interfaces operating in this mode can either send or receive packets at agiven time.z Auto-negotiation mode (auto). Interfaces operating in this mode determine their duplex modethrough auto-negotiation.Similarly, if you configure the transmission rate for an Ethernet port by using the speed command withthe auto keyword specified, the transmission rate is determined through auto-negotiation too. For aGigabit Layer 2 Ethernet port, you can specify the transmission rate by its auto-negotiation capacity. Fordetails, refer to.Configuring an Auto-negotiation Transmission Rate.Follow these steps to configure an Ethernet port:To do… Use the command… RemarksEnter system view system-view —Enter Ethernet port view interface interface-typeinterface-number —Set the description string description textOptionalBy default, the description of aninterface is the interface namefollowed by the “Interface” string,GigabitEthernet1/0/1 Interfacefor example.
