Ethernet interface configuration commands
General Ethernet interface configuration
commands
combo enable
Use combo enable to activate the copper or fiber combo port of a combo interface.
Syntax
combo enable { copper | fiber }
Default
The copper combo port of a combo interface is activated.
Views
Ethernet interface view (combo interface)
Default command level
2: System level
Parameters
copper: Activates the copper combo port. In this case, use twisted pairs to connect the port.
fiber: Activates the fiber combo port. In this case, use optical fibers to connect the port.
Usage guidelines
A combo interface is a logical interface that physically comprises one fiber combo port and one copper
combo port on the device panel. The two ports share one forwarding interface. As a result, they cannot
work simultaneously. When you activate either port, the other port is automatically disabled. You can
select to activate the copper combo port or fiber combo port.
Support for this command depends on the device model. For more information, see About the Command
References for HP Unified Wired-WLAN Products.
Examples
# Activate the copper combo port of combo interface GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] combo enable copper
# Activate the fiber combo port of combo interface GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] combo enable fiber

default
Use default to restore the default settings for an Ethernet interface.
Syntax
default
Views
Ethernet interface view
Default command level
2: System level
Usage guidelines
CAUTION:
The default command might interrupt ongoing network services. Make sure you are fully aware of the
impacts of this command when you use it in a live network.
This command might fail to restore the default settings for some commands for reasons such as command
dependencies and system restrictions. Use the display this command in interface view to identify these
commands, and then use their undo forms or follow the command reference to individually restore their
default settings. If your restoration attempt still fails, follow the error message instructions to resolve the
problem.
Examples
# Restore the default settings for interface Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] default
This command will restore the default settings. Continue? [Y/N]:y
description
Use description to change the description of the interface.
Use undo description to restore the default.
Syntax
description text
undo description
Default
The default description of an interface is the interface name plus Interface. For example,
Ten-GigabitEthernet1/0/1 Interface.
Views
Ethernet interface view
Default command level
2: System level

3
Parameters
text: Specifies the interface description, a case-sensitive string of 1 to 80 characters.
When you specify a description, follow these guidelines:
•Each Unicode character takes the space of two regular characters.
•To use Unicode characters or symbols in an interface description, install a specific IME and log in
to the device through remote login software that supports the character type.
•When the length of a description string reaches or exceeds the maximum line width on the terminal
software, the software starts a new line. This possibly breaks a Unicode character in half and might
result in garbled characters at the end of a line.
Examples
# Change the description of interface Ten-GigabitEthernet 1/0/1 to lanswitch-interface.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] description lanswitch-interface
Related commands
display interface
display interface
Use display interface to display Ethernet interface information.
Syntax

display interface interface-type [ interface-number ][ brief ] [ | { begin | exclude | include }
regular-expression ]
Views
Any view
Default command level
1: Monitor level
Parameters
interface-type: Specifies an interface type.
interface-number: Specifies an interface number.
brief: Displays brief interface information. If you do not specify this keyword, the command displays
detailed interface information.
down: Displays information about interfaces in the down state and the causes. If you do not specify this
keyword, this command displays information about interfaces in all states.
|: Filters command output by specifying a regular expression. For more information about regular
expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.

4
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Usage guidelines
If no interface type is specified, this command displays information about all interfaces.
If an interface type is specified but no interface number is specified, this command displays information
about all interfaces of the specified type.
