			MAX-ACCESS read-only
			STATUS current
			DESCRIPTION
				"This object represents the next available value for
				the object 'atNtpPeerIndex'. 
				
				For creation of a new entry in the 'atNtpPeerTable', 
				a management application should read this object, 
				get the value and use the same."

				the system.
				
				For creation of a new entry, the value of this object 
				should be same as that of the value of
				'atNtpPeerIndexNext' object. If this is not
				the case, then the entry creation will fail."
			::= { atNtpPeerEntry 1 }

			SYNTAX DisplayString
			MAX-ACCESS read-write
			STATUS current
			DESCRIPTION
				"This object represents host name, or the IP address,
				of the NTP peer.
				
				This object is a current object for row creation.
				
				When a new row is created, this object is set with

			DESCRIPTION
				"This object specifies whether this peer is the 
				preferred one over the others.
				
				It's value is encoded as follows:
				0 - unknown
				1 - not preferred
				2 - preferred 
				
				When the value of this object is 'not preferred',
				NTP chooses the peer with which to synchronize the
				time on the local system. If this object is set to

				synchronize the time with.

			DEFVAL {0}
			::= { atNtpPeerEntry 6 }

		
		atNtpPeerRowStatus OBJECT-TYPE
			SYNTAX RowStatus
			MAX-ACCESS read-create
			STATUS current
			DESCRIPTION
				"The status of this row.
				
				The reading of this object should have a value of 
				'active(1)'.
				
				For creation of new entry, a management application 
				should set this object with value 'createAndGo(4)',
				and using the same value as that got from reading
				object 'atNtpPeerIndexNext', as the index for 
				the new entry.
				
				When an entry is created, the object 'atNtpPeerNameAddr'
				in the entry is set with a default value '0.0.0.0'.
				The management application should change it to
				a desired value with a SET operation. 
				
				The management application may need to take 
				additional SET operations to set values for other 
				objects, to ensure they have desired values.
				
				For deletion of entry, a management application 
				should set this object with value 'destroy(6)'.
				
				Once an entry is deleted, other entries in the table 
				which have bigger index than the deleted one, will 
				be indexed again. Therefore a management 
				application can effectively delete multiple entries
				by repeating the SET operation using the same index."
