nat instance

Function

The nat instance command creates a NAT instance and displays the NAT instance view.

The undo nat instance command deletes a NAT instance.

By default, no NAT instance is configured.

This command is supported only on the NetEngine 8000 F1A.

Format

nat instance instance-name [ id id [ simple-configuration ] ]

undo nat instance instance-name [ id id [ simple-configuration ] ]

Parameters

Parameter	Description	Value
instance-name	Specifies the name of a NAT instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
id id	Specifies the ID of a NAT instance.	The value is an integer ranging from 1 to 4095.
simple-configuration	Indicates a simplified NAT instance.	After the simple-configuration parameter is configured, a device automatically generates a service-instance-groupservice instance group named _default_ and binds the instance group to the backup group and the NAT instance to the instance group. Consequently, the NAT configuration is simplified by eliminating manual configurations. A device supports only a single simplified NAT instance.

Usage Guidelines

Usage Scenario

To create a NAT instance and enter the NAT instance view, run the nat instance command. A NAT instance allows you to configure NAT attributes. NAT configurations, such as configuring a NAT address pool and the NAT ALG function, can only be performed in the NAT instance view. If a NAT instance is to be created for the first time, a NAT instance ID must be specified in the nat instance command. If a NAT instance exists, running this command displays the view of the existing NAT instance.

Precautions

In VS mode, this command is supported only by the admin VS.

Example

# Create a NAT instance named cpe1 and enter the NAT instance view.

<HUAWEI> system-view
[~HUAWEI] nat instance cpe1 id 1
[*HUAWEI-nat-instance-cpe1]
