combo enable

Syntax

combo enable { copper | fiber }

View

Ethernet interface view (Combo interface)

Default Level

2: System level

Parameters

copper: Activates the electrical port of the Combo interface.

fiber: Activates the optical port of the Combo interface.

Description

Use the combo enable command to activate the electrical or optical port of a Combo interface.

By default, the electrical port of a Combo interface is activated.

Combo interfaces are logical interfaces. A Combo interface comprises one optical (fiber) port and one

electrical (copper) port. The two ports share one forwarding interface and thus cannot work

simultaneously. If the electrical port is enabled, the optical port is disabled automatically and vice versa.

Examples

# Activate the electrical port of Combo interface GigabitEthernet 4/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 4/0/1

[Sysname- GigabitEthernet4/0/1] combo enable copper

# Activate the optical port of Combo interface GigabitEthernet 4/0/1.

1-2

Default Level

2: System level

Parameters

text: Creates an interface description, a string of 1 to 80 characters. Valid characters and symbols

include English letters (A to Z, a to z), digits (1 to 9), special English characters, spaces, and other

Unicode characters and symbols.

z Each Unicode character takes the space of two regular characters.

z To use a type of Unicode characters or symbols in an interface description, install the specific input

method editor and log in to the router through remote login software that supports this character

type.

z 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 into two. As a result,

garbled characters may be displayed at the end of a line.

Description

Use the description command to change the description of the current interface.

Use the undo description command to restore the default.

The default description of an interface is the interface name plus Interface, GigabitEthernet4/0/1

Interface for example.

Related commands: display interface.

Examples

# Change the description of Ethernet subinterface GigabitEthernet 4/0/1.1 to l2-subinterface4/0/1.1.

<Sysname> system-view

Syntax

display interface [ interface-type [ interface-number | interface-number.subnumber ] ] brief [ | { begin |

exclude | include } regular-expression ]

View

Any view

Default Level

1: Monitor level

Parameters

interface-type: Specifies an interface type.

interface-number: Specifies an interface number.

1-3

interface-number.subnumber: Specifies a subinterface number, where interface-number is an interface

number; subnumber is the number of a subinterface created under the interface. The value range of

subnumber is 1 to 4094.

|: Filters command output by specifying a regular expression. For more information about regular

expressions, see CLI in the Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays the lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, which is a case sensitive string of 1 to 256

characters.

Description

Use the display interface brief command to display brief interface information.

z If neither interface type nor interface number is specified, this command displays information about

all interfaces.

z If only interface type is specified, this command displays information about interfaces of the

specified type.

z If both interface type and interface number are specified, this command displays information about

the specified interface.

Related commands: interface.

Table 1-1 display interface brief command output description

Field Description

The brief information of

interface(s) under route

mode:

The command displays brief information about Layer 3 interfaces

Link: ADM -

administratively down;

Stby - standby

The interface has been shut down by the network administrator. To recover its

physical layer state, perform the

undo shutdown

command.

Stby

indicates that the current interface is a standby interface. You can use the

display standby state

command to check the corresponding primary interface.

Protocol: (s) - spoofing

If the network layer protocol state of an interface is shown as up, but its link is an

on-demand link or not present at all, its protocol attribute includes the spoofing

flag (an

s

in parentheses). This attribute is typical of null and loopback interfaces.

Interface Interface name

Link

Physical link state of the interface:

z UP: The link is present.

z DOWN: The link is physically down.

z ADM: The link has been administratively shut down. To recover its physical

state, perform the undo shutdown command.

z Stby: The interface is a standby interface.

Protocol

Protocol connection state of the interface, which can be up or down. If the network

layer protocol state of the interface is up, but its link is an on-demand link or not

present at all, its protocol attribute includes the spoofing flag (an

Description

Use the display interface command to display detailed information about interfaces, including their

operating status.

z If neither interface type nor interface number is specified, the command displays detailed

information about all interfaces.

z If only interface type is specified, the command displays detailed information about all interfaces of

the particular type.

1-6

z If both interface type and interface number are specified, the command displays detailed

information about only the specified interface.

Related commands: interface.
