Some Express Connect partners have already connected their networks to the access points of Alibaba Cloud. If you choose one of these Express Connect partners, you need only to connect your data center to the access point of the Express Connect partner, and then request the Express Connect partner to create a hosted connection for you to access Alibaba Cloud.

Prerequisites

Step 1: Accept a shared port

After the Express Connect partner creates a shared port or transforms your VBR to a shared port, the Express Connect partner will notify you to accept the shared port. You must log on to the Express Connect console, accept the shared port, and then pay the resource usage fee.

Note If the payment is already completed by the Express Connect partner, you do not need to pay for the resource usage.
  1. Log on to the Express Connect console.
  2. In the top navigation bar, select the region and click Exclusive Physical Connection in the left-side navigation pane.
  3. On the Physical Connections page, find the shared Express Connect circuit that you want to manage and click Accept and Pay in the Actions column.
    Accept the shared port
  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 shared Express Connect circuit changes to Enabled and the status of the Construction Procedure changes to Complete.

Step 2: Create a VBR

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

Notice If the Express Connect partner has already created a VBR for you, you need only to request the Express Connect partner to add a shared port to the hosted connection with which the VBR is associated.
  1. Log on to the Express Connect console.
  2. In the top navigation bar, select the region and click Exclusive Physical Connection in the left-side navigation pane.
  3. On the Physical Connections page, find the shared Express Connect circuit that you want to manage and click its ID.
  4. On the Connected VBRs 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 are logged on.
    Name Enter a name for the VBR. The name must be 2 to 128 characters in length, and can contain letters, digits, underscores (_), and hyphens (-). The name must start with a letter and cannot start with http:// or https://.
    Physical Connection Interface In this example, Shared Physical Connection is selected. Then, you must select a shared Express Connect circuit from the drop-down list. Make sure that the Express Connect circuit is installed and works as expected.
    VLAN ID By default, the VLAN ID specified by the Express Connect partner is displayed. You cannot change the VLAN ID.
    Peer IPv4 Address of Gateway at Alibaba Cloud Side Specify an IPv4 address for the VBR.
    Peer IPv4 Address of Gateway at Customer Side Specify an IPv4 address for the gateway device in the data center.
    Subnet Mask (IPv4 Address) 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 a bandwidth limit for the VBR, modify the configurations of the VBR, or delete the VBR. For more information, see Create a VBR.

View data transfer monitoring data

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 click Exclusive Physical Connection in the left-side navigation pane.
  3. Find the shared Express Connect circuit that you want to view and click Monitor in the Monitor column.
    By default, the system displays monitoring data collected within the last day. 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: 1 hour, 6 hours, 12 hours, 24 hours, 1 day, 7 days, 15 days, and 30 days.
    • Custom time period: If you set the time granularity to hours, you can specify a time period of at most 24 hours. If you set the time granularity to days, you can specify a time period of at most 30 days.
