Manage Lingjun Connections

Limitations

• When the bandwidth of a Lingjun Connection is <= 400 Gbps, the maximum bandwidth for a single traffic flow is 1/4 of the total bandwidth.

• When the bandwidth of a Lingjun Connection is > 400 Gbps, the maximum bandwidth for a single traffic flow can reach 100 Gbps.

Manage configured Lingjun Connection instances

1. Log on to the Lingjun console.

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

3. Search for a configured Lingjun Connection instance by its instance ID or name.

4. View information about the configured Lingjun Connection, such as Instance ID/Name, CIDR Block, and Bandwidth.

   Note

   You can also click Purchase Lingjun Connection to purchase a new Lingjun Connection.

5. In the Lingjun Connection Traffic column, click the icon to open a real-time monitoring panel for the instance. This panel displays line charts for Normal Traffic Rate (Inbound) and Normal Traffic Rate (Outbound) and allows you to switch the measurement unit (Byte/bit) and select a time range.

6. In the Instances area, perform the following operations in the Actions column:

   • Renew.

   • Upgrade. To upgrade the Lingjun Connection, you must first pay for the new configuration. The fee is calculated based on the remaining days of the current subscription period.

   • Downgrade. If you downgrade the Lingjun Connection, the system issues a refund immediately. The refund amount is calculated based on the remaining days of the current subscription period.

Manage unconfigured Lingjun Connection instances

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

2. In the Instances to Be Configured, find the target Lingjun Connection instance.

3. For the target Lingjun Connection's Instance ID/Name, in the Actions column, click Configure Lingjun Connection.

4. Configure the Name and Connection Mode for the Lingjun Connection.

   Direct VPC connection

   The Lingjun Connection connects directly to a single VPC.

   Important

   If you select the Direct VPC Connection method:

   • If the required maximum bandwidth for the Lingjun Connection is greater than 10 Gbps, we recommend that you select the Direct VPC Connection method to avoid performance issues with the CEN-TR. For information about the bandwidth limits of a CEN-TR, see Cloud Enterprise Network limits.

   • You must add a route entry to the VPC to allow it to access the Lingjun Connection. For more information, see Create and manage a route table.

   • You must configure a health check for each of the four VBRs associated with the Lingjun Connection. For more information, see Configure a VBR health check.

   • You must add a route entry to the Lingjun Connection to allow it to access the VPC. For more information, see Create a static route entry.

   CEN-TR

   With a CEN-TR, the Lingjun Connection can connect to multiple VPCs. For information about CEN billing, see Billing.

   Important

   When you select CEN-TR as the connection method, the system automatically configures cloud services for the corresponding Cloud Enterprise Network (CEN) instance.

   CEN basic edition instances

   1. Log on to the Cloud Enterprise Network console.

   2. On the CEN Instances page, click the ID of the target CEN instance.

   3. On the Basic Information > Transit Router tab, click the ID of the transit router instance in the target region.

   4. Click the Access to Cloud Services tab.

   5. Verify that two cloud service configurations exist for the 100.64.0.0/11 and 100.96.0.0/11 CIDR blocks.

   CEN enterprise edition instances

   1. Log on to the Cloud Enterprise Network console.

   2. On the CEN Instances page, click the ID of the target CEN instance.

   3. On the Basic Information > Transit Router tab, click the ID of the transit router instance in the target region.

   4. Click the Transit Router Route Table > Route Entries tab.

   5. Verify that a static route entry with the destination CIDR block 100.64.0.0/10 exists.

5. Configure Network Information Monitoring. Select an existing VPC or create a new one to monitor the connectivity status of the Lingjun Connection. Make sure that a vSwitch within the VPC has at least one available IP address.

6. Click OK to finish the configuration.

Create a static route entry

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

2. In the Instances area, click the ID or name of the target Lingjun Connection instance.

3. Click the Route Entry tab, and then click Create Route Entry.

4. In the Create Route Entry to VPC panel, enter the Destination CIDR.

5. Click OK to create the route entry.

View Lingjun Connection route entries

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