Managing Connection Tags

Scenario

After a connection is created, you can view its tags or add, edit or delete a tag.

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

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 connections based on the tag policies. If you add a tag that does not comply with the tag policies, connections may fail to be created. Contact your administrator to learn more about tag policies.
