Answer

  • When a new network service is automatically added during ONTAP upgrade, ONTAP uses two methods simultaneously for this addition.
  • The two methods result in different default settings for the Allowed Addresses of the new network service:
    • Method 1
      • Directly add to the existing default network service policy under each SVM.
      • In this case, the default setting for Allowed Addresses is 0.0.0.0/0 :

Vserver         Policy Name          Service Name          Allowed Addresses
-------------------------------------------------------------------------------------
SVM1            default-management   backup-ndmp-control   0.0.0.0/0

  • Method 2
    • Add along with a new network service policy starting with custom- under each SVM.
    • In this case, the default setting for Allowed Addresses is -, meaning it is blank:

Vserver         Policy Name          Service Name          Allowed Addresses
-------------------------------------------------------------------------------------
SVM1            custom-data-12345    backup-ndmp-control             

  • There is an exception for admin SVM.
    • The existing custom-management- will be deleted, and a new network service policy starting with custom-system- will be added.
    • Depending on the system configuration, it is possible for both - (blank) and 0.0.0.0/0 to coexist for Allowed Addresses:

Vserver         Policy Name          Service Name          Allowed Addresses
-------------------------------------------------------------------------------------
ONTAP910        custom-system-112233  backup-ndmp-control   0.0.0.0/0
ONTAP910        custom-system-54321   backup-ndmp-control              
ONTAP910        custom-system-1234    backup-ndmp-control   0.0.0.0/0
