This topic describes how to attach tags to Cloud Enterprise Network (CEN) instances. Then, you can use tags to classify and search CEN instances.

Prerequisites

A CEN instance is created. For more information, see Create a CEN instance.

Background information

  • Tags are key-value pairs. Each tag consists of a key and a value. When you add a tag, you must specify a tag key but you can leave the tag value empty.
  • The keys of the tags that are attached to the same CEN instance must be unique. If you add a tag with a used key, the new tag overwrites the one that uses the same key.
  • You can attach up to 20 tags to a CEN instance.

Procedure

  1. Log on to the CEN console.
  2. On the Instances page, find the CEN instance that you want to manage.
  3. Click the Tag icon in the Tag column.
  4. Click Add. In the Configure Tags dialog box, add one or more tags.
