Express Connect:Operation guide for tenants

Prerequisites

• One of the following preparations is completed by the Express Connect partner:
  • A shared port is created to establish a new hosted connection. For more information, see Create a shared port for a new hosted connection.
  • A shared port is added to an existing hosted connection. For more information, see Create a shared port for an existing hosted connection of a tenant.
• Billing for outbound data transfer is enabled. For more information, see Enable billing for outbound data transfer.
• You have read and understood the billing rules of hosted connections over Express Connect circuits. For more information, see Billing of hosted connections over Express Connect circuits.

Procedure

Step 1: Accept a shared port

After the Express Connect partner creates a shared port for a new hosted connection or adds a shared port for your existing hosted connection, you must accept the shared port in the Express Connect console and pay the resource usage fee.

1. Log on to the Express Connect console.
2. In the top navigation bar, select a region based on your business requirements.
3. On the Physical Connection page, find the ID of the hosted connection that you want to manage and click Accept and Pay in the Actions column.
   
4. In the Accept message, click OK.
5. In the panel that appears, confirm the information such as the region and specification of the shared port, click Buy Now, and then complete the payment.
   After you complete the payment, the Status of the hosted connection changes to Enabled and the status of the Construction Procedure changes to Complete.

   Note After the tenant accepts the shared port, the Express Connect partner must confirm the shared port. Then, the VBR is associated with the newly added shared port. The configuration of the VBR is not modified and your service is not interrupted in this process. For more information, see Confirm a shared port.

Step 2: Create a VBR

After you accept the shared port, you must create a VBR to associate the VBR with the shared port. The VBR is used to exchange data between a virtual private cloud (VPC) and your data center. You can create only one VBR for each shared port.

1. Log on to the Express Connect console.
2. In the top navigation bar, select a region based on your business requirements.
3. On the Physical Connection page, click the ID of the hosted connection that you want to manage.
4. On the VBR tab, click Create VBR.
5. In the Create VBR panel, set the following parameters and click OK.

   Parameter	Description
   Account	By default, Current account is selected. If you use the default setting, the VBR that you create belongs to the account with which you log on to the console.
   Name	Enter a name for the VBR. The value must be 2 to 128 characters in length, and can contain letters, digits, underscores (_), and hyphens (-). It must start with a letter but cannot start with http:// or https://.
   Physical Connection Interface	In this example, Shared Physical Connection is selected. Then, you must select an Express Connect circuit that is enabled and functions as expected from the drop-down list.
   VLAN ID	By default, the virtual local area network (VLAN) ID specified by the Express Connect partner is displayed. You cannot change the VLAN ID.
   IPv4 Address (Alibaba Cloud Gateway)	Specify an IPv4 address for the VBR to route network traffic between the VPC and the data center.
   IPv4 Address (Data Center Gateway)	Specify an IPv4 address for the gateway device in the data center to route network traffic between the VPC and the data center.
   Subnet Mask (IPv4)	Enter the subnet mask of the IPv4 addresses that you specified for the VBR and the gateway device in the data center. You can enter a longer subnet mask because only two IP addresses are required.

   Note After you create the VBR, you can set the bandwidth of the VBR, modify the configuration of the VBR, or delete the VBR. For more information, see Create a VBR.

View monitoring data of data transfer

You can view the outbound data transfer of a shared port in the console.

1. Log on to the Express Connect console.
2. In the top navigation bar, select the region and then click Exclusive Physical Connection in the left-side navigation pane.
3. Find the hosted connection that you want to manage and click in the Monitor column.
   By default, the monitoring data within the last day is displayed. You can view monitoring data by hour or by day. The system allows you to select a predefined time period or specify a custom time range.

   • Predefined time periods:
     • To query monitoring data by day, select 1 day, 7 days, 15 days, or 30 days.
     • To query monitoring data by hour, select 1 hour, 6 hours, 12 hours, or 24 hours.
   • Custom time period: If you set the time granularity to Hourly, you can specify a time period in the last 24 hours. If you set the time granularity to Daily, you can specify a time period in the last 30 days.
