Configuring basic settings of an Ethernet interface

About Ethernet interface basic settings
You can configure an Ethernet interface to operate in one of the following duplex modes:
•
Full-duplex mode—The interface can send and receive packets simultaneously.
•
Half-duplex mode—The interface can only send or receive packets at a given time.
•
Autonegotiation mode—The interface negotiates a duplex mode with its peer.
You can set the speed of an Ethernet interface or enable it to automatically negotiate a speed with its
peer.
Restrictions and guidelines
The shutdown and port up-mode commands are mutually exclusive.
The shutdown command cannot be configured on an Ethernet interface in a loopback test.
