You can upgrade or downgrade a hosted connection or set a bandwidth limit for a virtual border router (VBR) to meet your business requirements.
Modify a hosted connection specification
You can modify the specification of a hosted connection, regardless of whether it is paid for by a tenant or a partner.
Before you begin, note the following information:
Use cases | Limitations | Effective time | Billing impact |
You can modify the specification of a hosted connection if its current bandwidth no longer meets your business requirements. | The combined bandwidth of all hosted connections on an express connect circuit cannot exceed the circuit's total bandwidth. | The new specification usually takes effect immediately. A delay of a few minutes may occur due to network issues. | When you upgrade a hosted connection, you must pay the price difference between the new and original specifications. When you downgrade, you can apply for a refund for the price difference. Note You can refer to Rules for canceling the subscription of an Alibaba Cloud service to apply for a refund of the resource reservation fee when you downgrade. |
Tenant-paid hosted connection
The tenant contacts the partner to request a specification modification.
The partner reviews the request to ensure that after the modification, the combined bandwidth of all hosted connections on the express connect circuit does not exceed the circuit's total bandwidth. After approval, the partner initiates the specification change for the tenant's hosted connection.
The partner initiates the specification change.
Log on to the Express Connect console.
In the top navigation bar, select a region.
On the Physical Connection page, click the target physical connection interface instance ID.
On the details page of the express connect circuit, click the Hosted Connections tab. On the Hosted Connections tab, find the tenant's hosted connection, and in the Actions column, click Modify Specification.
In the Modify Shared Port dialog box, select a bandwidth value from the Change Bandwidth Limit drop-down list, and then click OK.
The tenant confirms the change and completes the payment.
Log on to the Express Connect console.
In the top navigation bar, select a region.
On the Physical Connection page, find the target hosted connection, and in the Actions column, click Modify and Pay.
In the Modify and Pay panel, confirm the port specification to change, select the Terms of Service, and then click Buy Now and complete the payment.
Return to the Physical Connection page to view that the bandwidth of the shared circuit has been changed and Status is available. The partner side can also view in the Hosted Connections tab that the bandwidth of the shared circuit has been changed and the status is available.
After you modify the specification of a hosted connection, the system automatically adjusts the bandwidth of the associated VBR to ensure consistency.

Set a VBR bandwidth limit
Before you begin, note the following information:
Use cases | Limitations | Effective time |
You can set a bandwidth limit for a VBR if its current bandwidth no longer meets your business requirements. | When you set a bandwidth limit for a VBR, ensure that the total bandwidth of all VBRs on the express connect circuit does not exceed the circuit's total bandwidth. | After you set a bandwidth limit for a VBR, the new limit usually takes effect immediately. A delay of a few minutes may occur due to network issues. |
Log on to the Express Connect console.
In the top navigation bar, select a region.
On the Physical Connection page, click the target physical connection interface instance ID.
On the details page of the express connect circuit, click the VBR tab. Find the target VBR, and in the Actions column, choose
> Bandwidth Settings.In the Bandwidth Settings panel, set the Bandwidth Cap, and then click OK.
