After the using fortygige command is successfully configured, you do not need to reboot the switch.
You can view the 40-GE interface by using the display interface brief command.
After you combine the four 10-GE breakout interfaces, replace the dedicated 1-to-4 cable with a
dedicated 1-to-1 cable or a 40-GE transceiver module. For more information about the cable or
transceiver module, see the installation guides.
To combine four 10-GE breakout interfaces into a 40-GE interface:

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.

4. Set the duplex mode for
the Ethernet interface.
duplex
{

|
full
|
half
}
By default, the duplex mode is
auto
for
Ethernet interfaces.
Copper ports operating at 1000 Mbps or
10 Gbps and fiber ports do not support the
half
keyword.
5. Set the speed for the
Ethernet interface.
speed { 10 | 100 | 1000 |
10000 | 40000 | 100000 |
auto }
The default setting is
auto
for Ethernet
interfaces.
Support for the keywords depends on the
interface type. For more information, use
the
speed ?
command in interface view.
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.
