Tags can be used to identify resources with the same characteristics (such as elastic network interfaces that belong to the same organization or that serve the same purpose) for easy search and management. This topic describes how to edit the tags of an existing elastic network interface (ENI).

Background information

For information about how to use tags, the resources that support tags, and the limits on tags, see Overview and the "Tag limits" section of the Limits topic.


  1. Log on to the ECS console.
  2. In the left-side navigation pane, choose Network & Security > ENIs.
  3. In the top navigation bar, select a region.
  4. Find the ENI whose tags you want to edit, move the pointer over the edit-tag icon in the Tag column, and then click Edit Tags.
  5. In the Edit Tags dialog box, click Available Tags to select existing tags or click Create to create tags. Then, click OK.

What to do next

After tags are added to your ENIs, you can filter the ENIs by tag to perform different operations. For example, you can assign secondary private IP addresses to ENIs that have a set of tags and detach ENIs that have a different set of tags.
