Overview

Scenario

Tags can be used to identify SSL certificates. You can use tags to group certificates by usage, owner, or environment and manage them centrally.

Tag Naming Rules

• Each tag consists of a key-value pair.
• A maximum of 20 tags can be added for an SSL certificate.
• For each certificate, a tag key must be unique and can have only one tag value.
• A tag consists of a tag key and a tag value. The naming rules are listed in Table 1.
  

  If your organization has configured a tag policy for the CCM service, you need to add tags to resources based on the tag policy. If a tag does not comply with the policies, the tag may fail to be added for a certificate. Contact your organization administrator to learn more about tag policies.
