High-reliability mode supports the following combination types: optimal disaster recovery (apply for two access points and establish four independent dedicated connections), powerful disaster recovery (apply for two access points and establish two independent dedicated connections), development and testing (apply for one access point and establish two independent dedicated connections), and load balancing for large bandwidth (apply for multiple physical ports on the same access device). This topic describes how to apply for physical ports using different combination types of high-reliability mode.
Prerequisites
You have enabled outbound traffic billing.
Notes
Your port configuration must support the creation of multiple ports. If the port quota is exceeded, log on to the Quota Center to increase the quota.
When you purchase multiple ports, if the creation of any port fails, the entire purchase process fails. In this case, delete all the physical connection ports created in this purchase and reapply for physical ports in the corresponding mode.
Procedure
Step 1: Apply for physical ports in high-reliability mode
High-reliability mode allows you to apply for physical ports by selecting the following combination types:
Optimal disaster recovery
Log on to the Express Connect console, click Create Physical Connection Port, and select High Reliability Mode to apply for ports.
Select Optimal Disaster Recovery, click Next, configure the following parameters, and then click Next.
Parameter
Description
Port Type
You can select 1 GE Single-Mode Optical Port or 10 GE Single-Mode Optical Port.
Advanced Configuration
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.
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
Region
Select Express Connect circuit regions for access points 1 and 2. You can select two different regions.
Connectivity Provider
Select connectivity providers for access points 1 and 2. Different connectivity providers support different access points.
NoteChina Unicom, China Telecom, and China Mobile can use only their own dedicated connections and do not allow the use of dedicated connections provided by other carriers. Bare optical fiber access is not supported.
Access Point
Select appropriate access points for access points 1 and 2.
Confirm the connection information, select the billing rules, and click Submit.
After you select optimal disaster recovery to apply for ports, the system creates four physical port instances. Configure these four physical port instances according to Step 2 and Step 3.
NoteAfter the purchase is successful, each line has no direct resource association and is identified only by the numbering in the name. For example, if you purchase two ports in Hangzhou-Xiaoshan-A and two ports in Shanghai-Baoshan-C, the four ports created are named: Hangzhou-Xiaoshan-A-PConn1, Hangzhou-Xiaoshan-A-PConn2, Shanghai-Baoshan-C-PConn1, and Shanghai-Baoshan-C-PConn2.
If you receive an error message indicating that resources are insufficient at an access point, the port configuration exceeds the limit, or the resource port cannot meet your requirements, follow the instructions to resolve the issue.
Powerful disaster recovery
Log on to the Express Connect console, click Apply For Physical Port, and select High-reliability Mode to apply for ports.
Select Powerful Disaster Recovery, click Next, configure the following parameters, and then click Next.
