Tags let you categorize Anycast EIP instances for easier searching and filtering.

How tags work

As your Anycast EIP instance count grows, tags help you organize, search, and filter instances by group.

Tags are used to classify instances. Each tag consists of a key-value pair. Before you use tags, take note of the following limits:

  • Each tag key added to an instance must be unique.

  • You cannot create tags without adding them to instances. All tags must be added to instances.

  • Tag information is not shared across regions.

    For example, tags created in the China (Hangzhou) region are not displayed in the China (Shanghai) region.

  • You can modify the key and value of a tag or remove a tag from an instance. If you delete an instance, all tags added to the instance are deleted. This operation does not affect the tags added to other instances.

Limitations

You can attach a maximum of 20 tags to each Anycast EIP instance. This quota cannot be increased.

    If the Tags column is not displayed, click the 设置.png icon in the upper-right corner of the Anycast EIP list to display it.
