After an Express Connect partner acquires the permissions to create shared ports, the Express Connect partner can create shared ports for tenants to access resources on Alibaba Cloud. Each shared port can be associated with a virtual border router (VBR). This topic describes the operations that Express Connect partners must perform when tenants use pre-installed Express Connect circuits to connect to Alibaba Cloud.
Requirements
Before you start, make sure that the following requirements are met:
- Two or more Express Connect circuits are connected to different access points of Alibaba Cloud. Permissions to access a resource on Alibaba Cloud are acquired. To apply for permissions to access a resource on Alibaba Cloud, contact a customer business manager from Alibaba Cloud.
- The service terms in Limits on networks are met.
- The switch that connects to the network of the tenant supports bandwidth adjustment and traffic monitoring. Traffic monitoring is enabled for the switch to collect statistics about bandwidth (bit/s), packet loss rate (bit/s), packet forwarding rate (pps), and data transfer (bytes).
- The following traffic throttling features are configured on the customer-premises equipment (CPE): Quality of Service (QoS) policies and Address Resolution Protocol (ARP) throttling. In most cases, the limit is set to one ARP packet per second per tenant.
- If Internet Control Message Protocol (ICMP) throttling is configured, the limit on ICMP echo requests must be set to a value greater than 500 pps.
- A bandwidth limit is set for the hosted connection that you want to create for the tenant. The sum of bandwidth limits that you set for all hosted connections over an Express Connect circuit cannot be greater than the bandwidth limit of the Express Connect circuit.
- Assign a VLAN ID to each shared port. The VLAN IDs of shared ports that belong to the same Express Connect circuit must be unique.
- For tenants that require high availability, they can associate their shared ports with different Express Connect circuits for redundancy.
Prerequisites
- Permissions to create shared ports are acquired after you Submit a ticket.
- The Express Connect circuits are installed and enabled. For more information, see Create a dedicated connection over an Express Connect circuit.
- To create a shared port for a new hosted connection, you must acquire the account ID of the tenant.
- To create a shared port for an existing hosted connection of a tenant, take note of
the following items:
- Before you start, you must notify the tenant and request the tenant to enable outbound data transfer billing.
- Make sure that the VBR associated with the hosted connection supports bandwidth adjustment. If the VBR does not support bandwidth adjustment, Submit a ticket to acquire the required permissions.
- By default, the tenant must pay for the shared port. If you want to pay for the shared port with the current Express Connect partner account, Submit a ticket to acquire the required permissions.
Create a shared port for a new hosted connection
If this is the first time a tenant uses your pre-installed Express Connect circuit, you must create a shared port to establish a connection based on the business requirements of the tenant.
Create a shared port for the existing hosted connection of a tenant
If you have created a hosted connection for a tenant before, you can add a shared port to the hosted connection. Your service is not interrupted in this process. The newly added shared port is displayed in the tenant account. After the tenant accepts the shared port, you must confirm it in the console. Then, the VBR is automatically transferred to the tenant account and associated with the shared port.
After the VBR is transferred to the tenant account, Alibaba Cloud no longer charges VBR fees. If you have prepaid VBR fees, you can request a refund. For more information, see Rules for canceling the subscription of an Alibaba Cloud service.
View monitoring data of data transfer
You can view the outbound data transfer of a shared port in the console.
Modify the VLAN ID of a shared port
VBRs that belong to different VLANs are isolated from each other based on the VLAN IDs of the shared ports associated with the VBRs. Express Connect partners can change the VLAN IDs of shared ports as needed. However, the VLAN ID of each shared port must be unique in the same Express Connect circuit.
- Log on to the Express Connect console.
- In the top navigation bar, select the region and click Exclusive Physical Connection in the left-side navigation pane.
- On the Exclusive Physical Connection page, click the ID of the Express Connect circuit.
- Click the Shared Physical Connection tab, find the shared Express Connect circuit that you want to manage and click Edit in the Actions column.
- In the Modify Shared Port dialog box, specify VLAN ID and click OK.
Disable an instance
You can disable instances in your Express Connect service after the instances become overdue. For example, you can disable a connection over an Express Connect circuit, a VBR, or a shared port. Disabled instances will not be charged or automatically released. You can resume the instances anytime.
Delete a VBR
You can delete VBRs that you no longer need. You can delete VBRs within your account anytime. To delete a VBR that belongs to another account, disable the VBR first. For more information, see Disable an instance.
- Log on to the Express Connect console.
- In the top navigation bar, select the region and click Exclusive Physical Connection in the left-side navigation pane.
- On the Exclusive Physical Connection page, click the ID of the Express Connect circuit.
- On the Connected VBRs tab, find the VBR that you want to delete and choose in the Actions column.
- In the Delete VBR message, click OK.
Delete a shared port
You can delete shared ports that you no longer need. Before you delete a shared port, you must delete the VBR that is associated with the shared port. For more information, see Delete a VBR.
- Log on to the Express Connect console.
- In the top navigation bar, select the region and click Exclusive Physical Connection in the left-side navigation pane.
- On the Exclusive Physical Connection page, click the ID of the Express Connect circuit.
- Click the Shared Physical Connection tab, find the shared port that you want to delete and click Delete in the Actions column.
- In the Confirm Deletion message, click OK.
