This topic describes how to apply for a physical port using classic mode.

Prerequisites

You have already enabled billing for outbound traffic.

Procedure

Step 1: Apply for a classic mode physical port

Log on to the Express Connect management 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 carrier that provides the Express Connect circuit service. Different carriers offer different access points. Note China Unicom, China Telecom, and China Mobile can only use their own Express Connect circuits. They are not allowed to use Express Connect circuits provided by other carriers and do not support bare optical fiber access.
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 100GE Single-mode Optical Port, 40GE Single-mode Optical Port, GE Single-mode Optical Port, and 10GE Single-mode Optical Port types. Port Connection Requirements Alibaba Cloud Side Port Requirements: By default, a single-mode optical transceiver module with a data transmission distance of 10 kilometers or less is provided (matching Alibaba Cloud GE single-mode optical port and 10GE single-mode optical port). Customer Side Port Requirements: You need to purchase the optical transceiver module on the customer side by yourself, and you must ensure that the specifications of the customer side optical transceiver module are consistent with those of the Alibaba Cloud side optical transceiver module.
Advanced Configurations	Click Advanced Configuration to support selecting VBR Throttling, IPv6, BFD, MPBGP, MPBGP-v6, Qos, and VBR-HA capabilities. If the backend resources of the advanced capabilities you selected do not have corresponding advanced capability ports, the creation will fail. Advanced Capability Extended Reading VBR Throttling: Supports VBR granularity bandwidth throttling to avoid abnormal port utilization caused by excessive traffic of a single VBR. IPv6: Physical ports support IPv6 traffic transmission, enabling dedicated line communication between local IDC and cloud VPC. BFD: Supports detecting the connectivity of the direct link between the physical port and the peer device (such as optical fiber break or optical transceiver module fault). MPBGP: An extension of the BGP protocol that supports the transmission of multi-protocol routing information in BGP sessions. MPBGP-v6: An extension of the MPBGP protocol that supports the transmission of IPv6 routing information in BGP sessions. QoS: Defines different priorities for different services through QoS policies to ensure that high-priority services can obtain the required bandwidth first. Important The QoS policy feature is in invitational preview. If you need to use it, contact your account manager to apply. VBR-HA: Supports configuring two VBRs as a failover group. When BFD detects a link fault, traffic is automatically switched to the backup VBR, achieving sub-second switching and smooth business transition.
Resource Group	Select an existing resource group to achieve grouped management of physical ports.
Tag Key	Select existing tag keys and tag values, or enter new tag keys and tag values. By binding specific tags to physical port instances, you can manage instances by classification.
Tag Value

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