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.
•
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. For a 100-Mbps or 1000-Mbps Layer 2 Ethernet interface, you can also set speed options for
autonegotiation. The two ends can select a speed only from the available options. For more information,
see "

4.
Set the duplex mode for
the Ethernet interface.

By default:
•
The duplex mode is
full
for 10-GE and
40-GE interfaces.
•
The duplex mode is
auto
for other
Ethernet interfaces.
Fiber ports do not support the
half

By default, an Ethernet interface
autonegotiates its speed.
6.
Set the expected
bandwidth for the
Ethernet interface.
bandwidth
bandwidth-value
By default, the expected bandwidth (in
kbps) is the interface baud rate divided by
1000.
