Ethernet interface configuration commands
General Ethernet interface and subinterface
configuration commands
bandwidth
Use bandwidth to set the intended bandwidth for an Ethernet interface.
Use undo bandwidth to cancel the configuration.
Syntax
bandwidth bandwidth-value
undo bandwidth
Views
Ethernet interface/subinterface view
Default command level
2: System level
Parameters
bandwidth-value: Sets the intended bandwidth in the range of 1 to 4294967295 kbps.
Usage guidelines
You can obtain the intended bandwidth of an interface by querying the ifspeed value of the MIB node
with third-party software.
The intended bandwidth is used by network management systems for monitoring bandwidth, but does
not affect the actual bandwidth of the interface.
Examples
# Set the intended bandwidth to 10,000 kbps for interface Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] bandwidth 10000
combo enable
Use combo enable to activate the copper or fiber combo port.
Syntax
combo enable { copper | fiber }
Default
The copper combo port is activated.
2
Views
Ethernet interface view (combo interface)
Default command level
2: System level
Parameters
copper: Activates the copper(electrical) combo port.
fiber: Activates the fiber (optical) combo port.
Usage guidelines
The following matrix shows the command and router compatibility:

combo
enable No No No No
Applicable to only
MSR30-40 and
MSR30-60
Yes No
Combo interfaces are logical interfaces. A combo interface comprises one fiber combo port and one
copper combo port. The two ports cannot work simultaneously. If one port is enabled, the other port is
automatically disabled.
The LINK LED of a GE combo interface might be on when you insert or remove a transceiver module into
or from the combo interface whose fiber combo port is active on an MSR50 router, SIC-1GEC module,
XMIM-16FSW module, or XMIM-24FSW module. To solve the problem, shut down the combo interface
with the shutdown command and then bring it up with the undo shutdown command.
Examples
# Activate the copper combo port of combo interface GigabitEthernet 1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/1
[Sysname-GigabitEthernet1/1] combo enable copper
# Activate the fiber combo port of combo interface GigabitEthernet 1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/1
[Sysname-GigabitEthernet1/1] combo enable fiber
default
Use default to restore the default settings for an Ethernet interface or subinterface.
Syntax
default
Views

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 Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] default
This command will restore the default settings. Continue? [Y/N]:y
# Restore the default settings for subinterface Ethernet 1/1.1.
<Sysname> system-view
[Sysname] interface ethernet 1/1.1
[Sysname-Ethernet1/1.1] 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, Ethernet1/1
Interface.
Views
Ethernet interface view, Ethernet subinterface view
Default command level
2: System level
Parameters
text: Specifies the interface description, a string of 1 to 240 characters. The string can include
case-sensitive letters, digits, special characters such as tilde (~), exclamation point (!), at sign (@), pound
sign (#), dollar sign ($), percent sign (%), caret (^), ampersand sign (&), asterisk (*), left brace({), right
brace (}), left parenthesis ((), right parenthesis ()), left bracket ([), right bracket (]), left angle bracket (<),
right angle bracket (>), hyphen (-), underscore(_), plus sign (+), equal sign (=), vertical bar (|), back
4
slash (\), colon (:), semi-colon (;) quotation marks ("), apostrophe ('), comma (,), dot (.), and slash (/),
spaces, and other Unicode characters and symbols.
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 the specific input method
editor 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, possibly breaking a Unicode character in half. This might
result in garbled characters at the end of a line.
Examples
# Change the description of interface Ethernet 1/1 to lanswitch-interface.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] description lanswitch-interface
# Change the description of Ethernet subinterface Ethernet 1/1.1 to l2-subinterface1/1.1.
<Sysname> system-view
