| Description | An indication of whether messages sent on behalf of
this user to/from the SNMP engine can be authenticated,
and if so, the type of authentication protocol which is
used.
An instance of this object is created concurrently
with the creation of any other object instance for
the same user (i.e., as part of the processing of
the set operation which creates the first object
instance in the same conceptual row).
If an initial set operation (i.e. at row creation time)
tries to set a value for an unknown or unsupported
protocol, then a 'wrongValue' error must be returned.
Once instantiated, the value of such an instance of
this object can only be changed via a set operation to
the value of the usmNoAuthProtocol.
If a set operation tries to change the value of an
existing instance of this object to any value other
than usmNoAuthProtocol, then an 'inconsistentValue'
error must be returned.
If a set operation tries to set the value to the
usmNoAuthProtocol while the
ccmCommonUserSNMPPrivProtocol value in the same row is
not equal to usmNoPrivProtocol, then an
'inconsistentValue' error must be returned. That means
that an SNMP command generator application must first
ensure that the usmUserPrivProtocol is set to the
usmNoPrivProtocol value before it can set the
usmUserAuthProtocol value to usmNoAuthProtocol.
The value of an instance of this object directly maps
to a corresponding instance of usmUserAuthProtocol in
the usmUserTable. |
