Configuring basic settings of an Ethernet interface or
subinterface
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.
•
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.
