You can modify the bandwidth limits of hosted connections and virtual border routers (VBRs) based on your business requirements.
Modify the bandwidth limit of a hosted connection
You can modify the bandwidth limits of hosted connections that are paid by tenants and Express Connect partners.
Before you perform this operation, take note of the following limits.
Scenario | Limit | Effective time | Impact on billing |
If the bandwidth limit of a hosted connection does not meet your business requirements, you can modify the bandwidth limit. | The total bandwidth of all hosted connections that are created over an Express Connect circuit cannot exceed the bandwidth of the Express Connect circuit. | In most cases, after you modify the bandwidth limit of a hosted connection, the modification immediately takes effect. You may need to wait a few minutes for the modification to take effect due to network latency. | When you increase the bandwidth limit of a hosted connection, you are charged for the difference between the original port specification and the new port specification. When you decrease the bandwidth limit of a hosted connection, you can apply for a refund for the difference between the original port specification and the new port specification. Note For more information about how to apply for a refund, see Rules for canceling the subscription of an Alibaba Cloud service. |
Modify the bandwidth limit of a hosted connection paid by a tenant
The tenant contacts the Express Connect partner to modify the bandwidth limit of the hosted connection.
The Express Connect partner verifies that the new bandwidth limit requested by the tenant does not cause the total bandwidth of all hosted connections to exceed the bandwidth of the Express Connect circuit. If this condition is met, the Express Connect partner can modify the bandwidth limit of the hosted connection.
The Express Connect partner modifies the bandwidth limit of the hosted connection.
Log on to the Express Connect console.
In the top navigation bar, select a region.
On the Physical Connection page, click the ID of the Express Connect circuit that you want to manage.
On the details page, click the Shared Physical Connection tab. On the Shared Physical Connection tab, find the hosted connection of the tenant and click Modify Specification in the Actions column.
In the Modify Shared Port dialog box, configure the Change Bandwidth Limit parameter and then click OK.
The tenant confirms the bandwidth modification 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 Express Connect circuit that you want to manage and click Modify and Pay in the Actions column.
In the Modify and Pay panel, confirm the bandwidth limit, select Terms of Service, click Buy Now, and then complete the payment.
Return to the Physical Connection page. The page displays that the bandwidth limit of the hosted connection changes to the specified value and the Status of the hosted connection changes to Enabled. The Express Connect partner can view that the bandwidth limit of the hosted connection changes to the specified value and that the hosted connection is available on the Shared Physical Connection tab.
The system automatically changes the bandwidth limit of the VBR to the new bandwidth limit of the hosted connection.

Return to the Shared Physical Connection tab. The bandwidth limit of the hosted connection changes to the specified value. In addition, the Status of the hosted connection changes to Enabled. The tenant can view that the bandwidth limit of the hosted connection changes to the specified value and that the hosted connection is available on the Physical Connection page.
The system automatically changes the bandwidth limit of the VBR to the new bandwidth limit of the hosted connection.
Modify the bandwidth limit of a VBR
Before you perform this operation, take note of the following limits.
Scenario | Limit | Effective time |
If the bandwidth limit of a VBR does not meet your business requirements, you can modify the bandwidth limit of the VBR. | The total bandwidth of all VBRs that belong to an Express Connect circuit cannot exceed the bandwidth of the Express Connect circuit. | In most cases, after you modify the bandwidth limit of a VBR, the modification immediately takes effect. You may need to wait a few minutes for the modification to take effect due to network latency. |
Log on to the Express Connect console.
In the top navigation bar, select a region.
On the Physical Connection page, click the ID of the Express Connect circuit that you want to manage.
On the VBR tab of the details page, find the VBR that you want to manage and choose
> Bandwidth Settings in the Actions column. In the Bandwidth Settings panel, configure the Bandwidth Cap parameter and then click OK.
