Platform For AI:Create and manage LENIs

Overview

Attributes

The following table describes the attributes of an LENI.

Usage notes

An LENI is a network interface that is associated with a Lingjun node so that the Lingjun node can communicate with other resources. When you use an LENI, take note of the following items:

• Multiple secondary private IP addresses can be assigned to a single LENI, each of which can be removed from the LENI.

• If an LENI is released, the secondary private IP addresses that are assigned to the LENI are automatically reclaimed.

• If the Lingjun node with which an LENI of the user type is associated is scaled in or reinstalled, the LENI is automatically reclaimed.

Prerequisites

• A Lingjun node is purchased. For more information, see the "Purchase a node" section of the Manage Lingjun clusters and nodes topic.

• A VPC and a vSwitch are created. The vSwitch and the Lingjun node reside in the same zone. For more information, see Create and manage a VPC.

Limits

Create an LENI

1. Log on to the Intelligent Computing Lingjun console.

2. In the left-side navigation pane, choose Network Resources > Elastic Network Interfaces.

3. On the Elastic Network Interface page, click Create ENI.

4. On the Create ENI page, configure the parameters and click OK. The following table describes the key parameters.

   Parameter	Description
   Zone	The zone in which the associated Lingjun node resides.
   Node ID	The ID of the associated Lingjun node.
   VPC	The VPC to which the LENI is connected.
   vSwitch	The vSwitch in which the LENI is deployed. The vSwitch and the associated Lingjun node must reside in the same zone.
   Description	The description of the LENI for identification.

Manage LENIs

View LENIs

1. Log on to the Intelligent Computing Lingjun console.

2. In the left-side navigation pane, choose Network Resources > Elastic Network Interfaces.

3. On the Elastic Network Interface page, select Instance ID, Node ID, IP, Status, or Type from the drop-down list and enter a keyword to filter the LENIs that meet the filter conditions.

4. Click the ID of an LENI to view the details of the LENI.

Add a secondary private IP address to an LENI

1. Log on to the Intelligent Computing Lingjun console.

2. In the left-side navigation pane, choose Network Resources > Elastic Network Interfaces.

3. On the Elastic Network Interface page, find the LENI that you want to manage. Click the ID of the LENI to go to the details page of the LENI.

4. On the Manage Secondary Private IP Addresses tab, click Add to add a secondary private IP address to the LENI.

   • If you want to add a specific secondary private IP address, enter the IP address in the Secondary Private IP Address column. Then, click OK in the Actions column.

   • If you want to add a random secondary private IP address, directly click OK in the Actions column. In this case, the added secondary private IP address is first in the In Progress state. After the secondary private IP address is assigned, the secondary private IP address is displayed. The state of the secondary private IP address becomes Available.

Remove a secondary private IP address from an LENI

2. On the Manage Secondary Private IP Addresses tab, find the secondary private IP address that you want to remove. Click Delete in the Actions column.

   Note

   You can remove a secondary private IP address only if the IP address is in the Available or Unavailable state.

Delete an LENI

1. Log on to the Intelligent Computing Lingjun console.

2. In the left-side navigation pane, choose Network Resources > Elastic Network Interfaces.

3. On the Elastic Network Interface page, find the LENI that you want to manage. Click Delete in the Actions column. Follow the on-screen instructions to delete the LENI.
