The NTP client authentication configures the device to authenticate the time sources to which the local clock is synchronized. When you enable NTP authentication, the device synchronizes to a time source only if the source carries one of the authentication keys specified by the ntp trusted-key command. The device drops any packets that fail the authentication check and prevents them from updating the local clock. NTP authentication is disabled by default.

[V] top:System The APIC uses a policy model to combine data into a health score. Health scores can be aggregated for a variety of areas such as for the infrastructure, applications, or services. The category health score is calculated using a Lp -Norm formula. The health score penalty equals 100 minus the health score.

 ├
[V] fault:Delegate Exposes internal faults to the user. A fault delegate object can be defined on IFC (for example, for an endpoint group) and when the fault is raised (for example, under an endpoint policy on a switch), a fault delegate object is created on IFC under the specified object. A fault delegate object follows the lifecycle of the original fault instance object, being created, modified, or deleted based on the changes of the original fault.

[V] naming:NamedObject An abstract base class for an object that contains a name.

[V] pol:Obj Represents a generic policy object.
 
 ├
[V] pol:Comp Represents a policy component. This object is part of the policy definition.
 
 
 ├
[V] datetime:ANtpAuthKey This object is a digital signature. The usual data packet plus the key is used to build a non-reversible number that is appended to the packet. The receiver (having the same key) does the same computation and compares the result. If the results match, authentication succeeds.

Primitive Type: scalar:Bitmask32

Units: null
Encrypted: false

Category: TopLevelStatus
    Comments:

Constants
created 2u created In a setter method: specifies that an object should be created. An error is returned if the object already exists.
In the return value of a setter method: indicates that an object has been created.
modified 4u modified In a setter method: specifies that an object should be modified
In the return value of a setter method: indicates that an object has been modified.
deleted 8u deleted In a setter method: specifies that an object should be deleted.
In the return value of a setter method: indicates that an object has been deleted.
DEFAULT 0 --- This type controls the life cycle of objects passed in the XML API.

When used in a setter method (such as configConfMo), the ModificationStatus specifies whether an object should be created, modified, deleted or removed.
In the return value of a setter method, the ModificationStatus indicates the actual operation that was performed. For example, the ModificationStatus is set to "created" if the object was created. The ModificationStatus is not set if the object was neither created, modified, deleted or removed.

When invoking a setter method, the ModificationStatus is optional:
If a setter method such as configConfMo is invoked and the ModificationStatus is not set, the system automatically determines if the object should be created or modified.
