When you apply for a private endpoint for a Tair instance, make sure that the vSwitch to which the Tair instance is connected has sufficient IP addresses that can be allocated. This topic describes how to query the number of IP addresses available on a vSwitch.
Background information
After you apply for a private endpoint for a Tair instance, an IP address is allocated to the master node of each shard and another IP address is allocated to the private endpoint. If the vSwitch cannot provide sufficient IP addresses, the private endpoint cannot be enabled. For more information, see Enable the direct connection mode.
Procedure
Log on to the Tair console and go to the Instances page. In the top navigation bar, select the region in which the instance that you want to manage resides. Then, find the instance and click the instance ID.
In the Basic Information section, copy the vSwitch ID and click the virtual private cloud (VPC) ID.
You are directed to the VPC console.
On the details page of the VPC, click the Resource Management tab and then click the number corresponding to the vSwitch field.
Paste the vSwitch ID in the search box and click the Search icon to search for the vSwitch.
After you find the vSwitch, view the number of available IP addresses that can be allocated by the vSwitch in the Available IP Addresses column.
