Binding a Global Connection Bandwidth

Scenarios

You can bind a global connection bandwidth to a global EIP or a cloud connection.

Constraints

• Instances that a global connection bandwidth is to be bound to must be from the same region as the bandwidth.
• A global connection bandwidth can only be bound to instances of the same type. If you want to add other type of instances to a global connection bandwidth with instances bound, you need to remove the bound instances first.
  • Global EIPs: You can add or remove global EIPs in batches.
  • Cloud connections: You can bind one global connection bandwidth to or unbind it from one cloud connection at a time.
• If use a global connection bandwidth on a central network, you need to configure cross-region connections by performing the following operations:
  • Creating a Central Network
  • Managing Policies
  • Managing Attachments
• Global connection bandwidths of different types can be used with different instances. For details, see the following table.

  Table 1 Instances that can use a global connection bandwidth

  Bandwidth Type	Global EIP	Central Network
  Multi-city	√	×
  Cross-geographic-region	√	√
  Geographic-region	√	√

Using a Global Connection Bandwidth on a Central Network

1. Log in to the management console.
2. Click in the upper left corner and select the desired region and project.
3. On the console homepage, choose Networking > Cloud Connect.
4. In the navigation pane on the left, choose Cloud Connect > Central Networks.
5. In the central network list, click the name of the target central network.
6. Switch to the Cross-Site Connection Bandwidths tab.
7. Locate the cross-region connection, and click Assign now in the Global Connection Bandwidth column.
8. On the Assign Cross-Site Connection Bandwidth page, select the global connection bandwidth.
9. Enter the bandwidth and click OK.

Binding Global EIPs to a Global Connection Bandwidth

1. Log in to the management console.
2. Click in the upper left corner and select the desired region and project.
3. On the console homepage, choose Networking > Cloud Connect.
4. In the navigation pane on the left, choose Intra-Cloud > Global Connection Bandwidths.
5. Locate the global connection bandwidth and click Add in the Operation column.
6. In the Add dialog box, set Instance Type to Global EIP.

   For a multi-city global connection bandwidth, select the two regions where the bandwidth will be used.

7. Search for global EIPs using keywords.
8. Select one or more global EIPs and click OK.
