This command might fail to restore the default settings for some commands because of command dependencies and system restrictions. You can use the display this command in interface view to check for these commands, and perform their undo forms or follow the command reference to individually restore their default settings. Follow the instructions in the error message to resolve the problem if the restoration attempt fails.

The default command might interrupt ongoing network services. Be fully aware of the impacts of this command when you perform it on a live network.

Examples

# Restore the default settings of WLAN-BSS interface 1.

<Sysname> system-view

[Sysname] interface wlan-bss 1

[Sysname-WLAN-BSS1] default

This command will restore the default settings. Continue? [Y/N]:y

description

Use description to set the description for the current interface.

Use undo description to restore the default.

Syntax

Default

The description for an interface is interface-name + Interface.

Default command level

2: System level

Parameters

text: Description for the current interface, a string of 1 to 80 characters. The device supports the following types of characters or symbols: standard English characters (numbers and case-sensitive letters), special English characters, spaces, and other characters or symbols that conform to the Unicode standard.

Usage guidelines

An interface description can be the mixture of English characters and other Unicode characters. The mixed description cannot exceed the specified length.

To use a type of Unicode characters or symbols in an interface description, you must install the corresponding IME and log in to the device through remote login software that supports this character type.

Each Unicode character or symbol (non-English characters) takes the space of two regular characters. 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 parts. As a result, garbled characters may be displayed at the end of a line.

Examples

# Set the description for WLAN-Radio 1/0/1 to To AP1.

<Sysname> system-view

[Sysname] interface wlan-radio 1/0/1

[Sysname-WLAN-Radio1/0/1] description To AP1

display interface wlan-bss
