After you attach tags to VPN gateways, you can search and filter the VPN gateways by tag. This topic describes how to attach tags to multiple VPN gateways at a time.
Background information
- The keys of tags that are attached to the same VPN gateway must be unique.
- Tags must be attached to VPN gateways.
- Tag information is not shared across regions.
For example, in the China (Shanghai) region, you cannot view tags of instances that are created in the China (Hangzhou) region.
- You can modify the key and value of a tag, or remove the tag. If you delete a VPN gateway, all the tags that are attached to it are removed.
