Usage guidelines

	CAUTION: The default command might interrupt ongoing network services. Make sure you are fully aware of the impact of this command when you use it on a live network.

 

This command might fail to restore the default settings for some commands for reasons such as command dependencies or system restrictions. Use the display this command in interface view to identify these commands. Use their undo forms or follow the command reference to 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 VE-L2VPN 100.

<Sysname> system-view

[Sysname] interface ve-l2vpn 100

[Sysname-VE-L2VPN100] default

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

# Restore the default settings for interface VE-L3VPN 100.

<Sysname> system-view

[Sysname] interface ve-l3vpn 100

[Sysname-VE-L3VPN100] default

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

description

Use description to configure a description for an interface.

Use undo description to restore the default.

Syntax

description text

undo description

Default

The description for an interface is VE-L2VPNnumber Interface, for example, VE-L2VPN100 Interface.

interface ve-l2vpn

Use interface ve-l2vpn to create an L2VE interface and enter its view, or enter the view of an existing L2VE interface.

Use undo interface ve-l2vpn to delete an L2VE interface.
