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 perform it on 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 Layer 2 aggregate interface Bridge-Aggregation 1.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] default

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

description

Use description to set a description for an interface. For example, you can include information such as the purpose of the interface for the ease of management.

Use undo description to restore the default setting.

Syntax

· If no keyword or argument is specified, the command clears the statistics of all interfaces in the system.

· If only the bridge-aggregation keyword is specified, the command clears the statistics of all Layer 2 aggregate interfaces.

· If the bridge-aggregation interface-number option is specified, the command clears the statistics of the specified Layer 2 aggregate interface.

· The bridge-aggregation keyword becomes available only after you create Layer 2 aggregate interfaces on the device.
