apply classic mode - Express Connect - Alibaba Cloud Documentation Center

By purchasing a physical port through classic mode, you can select the required dedicated connection access points from a drop-down list. This mode lets you choose the appropriate access point from the list, suitable for those with specific access requirements. This topic describes how to apply for a physical port in classic mode.

Prerequisites

You have already enabled billing for outbound traffic.

Procedure

Step 1: Apply for a physical port in classic mode

Log on to the Express Connect console, click Create Physical Connection port, and select Classic Mode to apply for a port.

Configuration	Description
Region	The region where the Alibaba Cloud resources are accessed.
Express Connect Circuit Provider	The ISP. The available access points vary based on the ISP. Note When selecting China Unicom, China Telecom, and China Mobile, you can lease lines only from the selected ISP and are not allowed to lease lines from other ISPs. Bare optical fibers are not supported.
Access Point	Select the access point closest to your IDC. For information about selecting the nearest access point, see Alibaba Cloud access points.
Cloud Box Name	Select a CloudBox device cluster. To purchase an Express Connect circuit for CloudBox, contact your account manager to apply for the required permissions.
Port Type	You can select 100 GE Single-Mode Optical Port, 40 GE Single-Mode Optical Port, GE Single-Mode Optical Port, and 10GE Single-Mode Optical Port types. Port connection requirements Requirements for ports on the Alibaba Cloud side: By default, Alibaba Cloud provides single-mode optical transceivers of the following specifications: 1 Gbit/s, 10 Gbit/s, 40 Gbit/s, and 100 Gbit/s. The data transmission distance of the transceivers is 10 kilometers. Only dual-fiber Express Connect circuits are supported. Requirements for ports on the client side: You must purchase optical transceivers for the client side. Make sure that the specifications of the optical transceivers on the client side are the same as those on the Alibaba Cloud side.
Advanced Configurations	Click Advanced Configuration. You can select VBR Bandwidth Limits, IPv6, BFD, MPBGP, MPBGP-v6, QOS, and VBR-HA. If the backend resources do not have ports with the advanced capabilities that you select, the creation fails. Advanced capabilities VBR Throttling: This feature supports bandwidth throttling at the VBR level to prevent a single VBR from consuming excessive traffic and causing abnormal port utilization. IPv6: Physical ports support IPv6 traffic transmission, which allows IPv6 dedicated connection communication between on-premises data centers and VPCs in the cloud. BFD: This feature supports the detection of direct link connectivity between physical ports and peer devices (such as optical fiber breaks and optical module failures). MPBGP: This is an extension of the BGP protocol that supports the transmission of multi-protocol routing information in BGP sessions. MPBGP-v6: This is an extension of the MPBGP protocol that supports the transmission of IPv6 routing information in BGP sessions. QoS: QoS policies define different priorities for different services to ensure that high-priority services can obtain the required bandwidth first. Important The QoS policy feature is in invitational preview. To use this feature, contact your account manager to apply for it. VBR-HA: This feature allows you to configure two VBRs as a failover group. When BFD detects a link failure, traffic is automatically switched to the backup VBR, achieving sub-second switching and smooth service transition.
Resource Group	Select an existing resource group to manage physical ports by group.
Tag Key	Select existing tag keys and tag values, or enter new tag keys and tag values. You can bind specific tags to physical port instances for categorized management.
Tag Value

Select the billing rules and click Confirm.
Note
After the Express Connect circuit construction is completed and the payment is successful, the Port Status of the Express Connect circuit port is UP. Before payment, the Port Status is Down.

Step 2: Apply for Express Connect circuit construction

Note

Alibaba Cloud supports secondary LOA applications. To apply, repeat the operations in Step 2: Apply for Express Connect circuit construction.

On the Physical Port page, find the port and click Apply for LOA.

In the Apply For LOA (letter Of Authorization For Express Connect Circuit Construction) panel, enter the following information and click OK.

Parameter	Description

Leased Line Type	You can select MSTP, MPLSVPN, Fiber Connection, or Others.
Construction Schedule	The time when the construction company will enter the data center.
Customer Data Center Location	The location of the data center.
Leased Line Bandwidth	Enter the bandwidth value specified in your Express Connect circuit contract. Note The bandwidth value here is only used as a reference for Alibaba Cloud service configuration. Your actual fees and bandwidth limit are based on the contract you signed with the carrier. Please fill in the actual contract bandwidth.
Add Field Engineer	Click Add Field Engineer to add information about the personnel who need to enter the Alibaba Cloud data center for construction. You can specify one or more field engineers. Important The field engineer information is required.

After you apply for an LOA, the LOA Status of the instance becomes LOA Being Applied. After the Alibaba Cloud reviewer approves the application within two business days, the LOA Status changes to LOA Approved.

Receive a text message notification and perform the following steps:
Note
You can skip this step if your access point is a third-party data center access point, or an access point in China (Hong Kong) or an international data center.
1. Obtain an entry credential: Click the entry credential link in the text message and log on to the entry application platform. Select the data center information and Confirm Visit, then click Entry Credential to obtain the entry QR code.
2. Complete your personal information:
  1. Copy the text message link to a computer browser and access the link. Read and agree to the privacy protection statement and the Alibaba Cloud data center entry agreement.
  2. Fill in your personal information and click Submit Information. When the page displays Submitted Successfully, you can close the browser window.

Step 3: Implement Express Connect circuit construction and pay the resource occupation fee

Implement Express Connect circuit construction
1. On the Physical Port page, find the instance, view, and download the LOA file.
2. Based on the LOA information, contact the Express Connect circuit construction company to connect the Express Connect circuit to the equipment outside the Alibaba Cloud data center room according to the survey plan.
