Platform For AI:Manage Lingjun connection instances

Limits

• If the bandwidth of a Lingjun connection is less than or equal to 400 Gbit/s, the bandwidth of a single data flow over the Lingjun connection can be up to one-fourth of the total bandwidth of the Lingjun connection.

• If the bandwidth of a Lingjun connection is greater than 400 Gbit/s, the bandwidth of a single data flow over the Lingjun connection can be up to 100 Gbit/s.

Manage a configured Lingjun connection instance

1. Log on to the Intelligent Computing Lingjun console.

2. In the left-side navigation pane, choose Network Resources > Lingjun Connections.

3. In the Instances section, search for the configured Lingjun connection instance based on the name and ID of the instance.

4. You can view the information about the Lingjun connection instance. The information includes the instance ID, CIDR block, and bandwidth.

   Note

   You can also click Purchase Lingjun Connection to purchase a Lingjun connection instance.

5. Click the icon in the Traffic column to view the traffic rate of the Lingjun connection instance.

6. In the Instances section, you can perform the following operations in the Actions column to dynamically upgrade or downgrade the bandwidth of the Lingjun connection instance within the bandwidth range:

   • Renew.

   • Upgrade. You must complete the payment first to upgrade the bandwidth of the Lingjun connection instance. You are charged based on the number of remaining days of your subscription.

   • Downgrade. If you downgrade the bandwidth of the Lingjun connection instance, a refund is made immediately. The refund is settled based on the number of remaining days of your subscription.

Manage a Lingjun connection instance to be configured

1. In the left-side navigation pane, choose Network Resources > Lingjun Connections.

2. Find the Lingjun connection instance that you want to manage in the Instances to Be Configured section.

3. Click Configure Lingjun Connection in the Actions column of the Lingjun connection instance.

4. Configure the parameters such as Name and Connection Mode.

   Direct Connection to VPC

   The Lingjun connection instance is directly connected to a single VPC.

   Important

   If you select Direct Connection to VPC as Connection Mode, take note of the following items:

   • If the maximum bandwidth required by the Lingjun connection instance is greater than 10 Gbit/s, we recommend that you select Direct Connection to VPC to prevent the actual bandwidth from being affected by the limits on transit routers of CEN. For more information, see Limits.

   • You must configure the routes from the VPC to the Lingjun connection instance. For more information, see Create and manage a route table.

   • You must configure the routes from the Lingjun connection instance to the VPC. For more information, see the Create static routes section of this topic.

   CEN-TR

   The Lingjun connection instance can connect to multiple VPCs by using a transit router of CEN. For more information about the billing of CEN, see Billing rules.

   Important

   If you select CEN as Connection Mode, the cloud services are automatically configured for the CEN instance to which the Lingjun connection instance is connected.

   CEN Basic Edition instance

   1. Log on to the CEN console.

   2. On the Instances page, click the ID of the CEN instance that you want to manage.

   3. On the Transit Router subtab of the Basic Settings tab, click the ID of the instance that resides in the same region as the Lingjun connection instance.

   4. Click Cloud Services.

   5. On the Cloud Services tab, you can view the configurations of the cloud services whose CIDR blocks are 100.64.0.0/11 and 100.96.0.0/11.

   CEN Enterprise Edition instance

   1. Log on to the CEN console.

   2. On the Instances page, click the ID of the CEN instance that you want to manage.

   3. On the Transit Router subtab of the Basic Settings tab, click the ID of the instance that resides in the same region as the Lingjun connection instance.

   4. Click Route Table.

   5. On the Route Entry subtab, you can view the configurations of a static route whose CIDR block is 100.64.0.0/10.

5. Configure the parameter in the Network Information Monitoring section. You can select an existing VPC or create a VPC to monitor the network connectivity of the Lingjun connection instance. Make sure that the vSwitches in the VPC that you want to use have at least one idle IP address.

6. Click OK. The Lingjun connection instance is configured.

Create static routes

1. In the left-side navigation pane, choose Network Resources > Lingjun Connections.

2. In the Instances section, click the name of the Lingjun connection instance for which you want to create static routes.

3. On the page that appears, click Route Entry. On the Route Entry tab, click Create Route Entry.

4. In the Create Route Entry to VPC panel, configure the Destination CIDR block parameter.

5. Click Yes. The static routes are created.

View the routes of a Lingjun connection instance

1. In the left-side navigation pane, choose Network Resources > Lingjun Connections.

2. In the Instances section, click the name of the Lingjun connection instance whose routes you want to view.

3. On the page that appears, click Route Entry. On the Route Entry tab, view the information about the routes of the Lingjun connection instance. The following table describes the fields of the route list.

   Field	Description
   Destination CIDR Block	The destination CIDR block of a route.
   Next Hop Type	The type of the next hop of a route. Valid values: VPDs Lingjun Connections Lingjun Hubs
   Next Hop Instance	The instance of the next hop of a route.
   Route Type	The type of a route. Valid values: SYSTEM: The destination CIDR block of the route is the CIDR block of the Lingjun connection. BGP: The Lingjun connection route automatically specifies the destination CIDR block by using the Border Gateway Protocol (BGP).
   Status	The status of a route.
   Last Modified At	The last time when a route was updated.

Delete static routes

1. In the left-side navigation pane, choose Network Resources > Lingjun Connections.
