This topic describes how to add tags to multiple Virtual Private Cloud (VPC) instances. You can use tags to label and classify VPCs, route tables, and VSwitches, which facilitates resource search and aggregation. The operation for adding tags to multiple route tables or VSwitches is similar to the procedure described in this topic.

Background information

You can only associate up to 20 tags with an instance. Tags are described as follows:
  • The key of each tag on an instance must be unique.
  • Tags must be associated with instances.
  • Tag information cannot be shared across regions.

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

  • The tags of VPCs, route tables, VSwitches, and Elastic IP Addresses (EIPs) in the same region and under the same account are interconnected.

    For example, if a tag is associated with a VPC, in order to associate this tag with the VSwitches, route tables, or EIPs which are in the same region and under the same account, you can go to the tag configuring pages of these resources and select this tag for association, instead of entering the tag key and value information manually.

  • You can modify the key and value of a tag or delete a tag of an instance at any time. If you delete an instance, all tags associated with the instance are also deleted.

Procedure

  1. Log on to the VPC console.
  2. In the top navigation bar, select the region of the VPC.
  3. On the VPCs page, select the instances you want to add tags to, and then click Configure Tags > Add Tags.
