Configuring basic settings of an Ethernet interface
You can set an Ethernet interface to operate in one of the following duplex modes:
 Full-duplex mode (full): Interfaces that operates in this mode can send and receive packets
simultaneously.
 Half-duplex mode (half): Interfaces that operates in this mode cannot send and receive packets
simultaneously.
 Auto-negotiation mode (auto): Interfaces that operates in this mode negotiate a duplex mode with
their peers.
You can set the speed of an Ethernet interface or enable it to automatically negotiate a speed with its
peer. For a 100-Mbps or 1000-Mbps Layer 2 Ethernet interface, you can also set speed options for auto
negotiation. The two ends can select a speed only from the available options. For more information, see
―Setting speed options for auto negotiation on an Ethernet interface.‖
