Step Command Remarks
2. Enter the view of any 10-GE
interface split from a 40-GE
interface.

3. Combine the four 10-GE
interfaces into a 40-GE
interface.
using fortygige
By default, a 40-GE interface is not
split and operates as a single
interface.
After you combine the four 10-GE
interfaces, replace the dedicated
1-to-4 cable with a dedicated
1-to-1 cable.
4. Reboot the card that houses
the interface.
N/A
After creating the 40-GE interface,
the system removes the four 10-GE
interfaces.
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 can send and receive packets simultaneously.
• Half-duplex mode (half)—Interfaces cannot send and receive packets simultaneously.
• Autonegotiation mode (auto)—Interfaces 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.
To configure an Ethernet interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Ethernet interface
view. interface interface-type
interface-number
N/A
3. Set the interface
description.
description text
The default setting is in the format of
interface-name Interface. For example,
Ten-GigabitEthernet1/0/1 Interface.
4. Set the duplex mode of
the Ethernet interface.
duplex { auto | full | half }
The default setting is auto for Ethernet
interfaces.
Copper ports operating at 1000 Mbps and
fiber ports do not support the half keyword.
You cannot configure the duplex mode for
a 100-GE CFP interface.
5. Set the port speed.
speed { 10 | 100 | 1000 |
10000 | 40000 | 100000 |
auto }
The default setting is auto for Ethernet
interfaces.
6. Configure the expected
bandwidth of the
interface.
bandwidth bandwidth-value
By default, the expected bandwidth (in
kbps) is the interface baud rate divided by
1000.
