Managing Virtual Interface Tags

Scenario

After a virtual interface is created, you can add tags to it, or edit, view or delete its tags.

A tag is the identifier of a virtual interface and consists of a key and a value. You can add 20 tags to a virtual interface.

If a predefined tag has been created on TMS, you can directly select the corresponding tag key and value.

For details about predefined tags, see Predefined Tag Overview.

If you have configured tag policies for Direct Connect, you need to add tags to your virtual interfaces based on the tag policies. If you add a tag that does not comply with the tag policies, virtual interfaces may fail to be created. Contact your administrator to learn more about tag policies.
