Editing DNS Sets

Use this task to edit existing DNS Sets.

When the DNS Sets page opens, the fields are populated with the currently configured values.

The DNS Set Name cannot be edited.

The fields are described in Peer Discovery DNS Sets elements.

1. Click Diameter > Configuration > Peer Discovery > DNS Sets.
2. Select the DNS Set Name to edit.
3. Click Edit.
4. Update the relevant fields.
5. Click OK, Apply, or Cancel.
   If OK or Apply is clicked and any of the following conditions exist, then an error message appears:

   • The selected DNS Set Name no longer exists; it has been deleted by another user.
   • The selected DNS Set Name is referenced by one or more administratively enabled Discovery Attributes.

     Note:

     You can edit an administratively disabled Discovery Attribute, because changing the DNS Set attributes has no impact on active Realm discovery.
   • Any validation checks fail.
   • Any required field is empty (no value was entered).
   • The value in any field is not valid or is out of range.
   • The DNS Set Name is not unique; it already exists in the system.
   • The maximum number of DNS Sets already exists in the system.
   • The secondary IP address duplicates the primary IP address.
   • The pair of IP addresses (primary/secondary) duplicates the pair already defined for another DNS Set.

     Note:

     Exchanging the primary and secondary IP addresses does not constitute a unique DNS set.
