cntpSysStratum

The stratum of the local clock. If the value is set to 1, i.e., this is a primary reference, then the Primary-Clock procedure described in Section 3.4.6, in RFC-1305 is invoked.

cntpSysPrecision

Signed integer indicating the precision of the system clock, in seconds to the nearest power of two. The value must be rounded to the next larger power of two; for instance, a 50-Hz (20 ms) or 60-Hz (16.67 ms) power-frequency clock would be assigned the ...

cntpSysRootDelay

A signed fixed-point number indicating the total round-trip delay in seconds, to the primary reference source at the root of the synchronization subnet.

cntpSysRefTime

The local time when the local clock was last updated. If the local clock has never been synchronized, the value is zero.

cntpSysPoll

The interval at which the NTP server polls other NTP servers to synchronize its clock.

cntpSysPeer

The current synchronization source. This will contain the unique association identifier cntpPeersAssocId of the corresponding peer entry in the cntpPeersVarTable of the peer acting as the synchronization source. If there is no peer, the value will be 0.

cntpPeersVarTable

This table provides information on the peers with which the local NTP server has associations. The peers are also NTP servers but running on different hosts.

cntpPeersVarEntry

Each peers' entry provides NTP information retrieved from a particular peer NTP server. Each peer is identified by a unique association identifier. Entries are automatically created when the user configures the NTP server to be associated with remote pee ...

cntpPeersAssocId

An integer value greater than 0 that uniquely identifies a peer with which the local NTP server is associated.

cntpPeersConfigured

This is a bit indicating that the association was created from configuration information and should not be de-associated even if the peer becomes unreachable.

cntpPeersPeerAddress

The IP address of the peer. When creating a new association, a value should be set either for this object or the corresponding instance of cntpPeersPeerName, before the row is made active.

cntpPeersPeerPort

The UDP port number on which the peer receives NTP messages.

cntpPeersHostAddress

The IP address of the local host. Multi-homing can be supported using this object.

cntpPeersHostPort

The UDP port number on which the local host receives NTP messages.

cntpPeersLeap

Two-bit code warning of an impending leap second to be inserted in the NTP timescale of the peer.

cntpPeersMode

The association mode of the NTP server, with values coded as follows, 0, unspecified 1, symmetric active - A host operating in this mode sends periodic messages regardless of the reachability state or stratum of its peer. By operating in this mode the ho ...

cntpPeersStratum

The stratum of the peer clock.

cntpPeersPeerPoll

The interval at which the peer polls the local host.

cntpPeersHostPoll

The interval at which the local host polls the peer.

cntpPeersPrecision

Signed integer indicating the precision of the peer clock, in seconds to the nearest power of two. The value must be rounded to the next larger power of two; for instance, a 50-Hz (20 ms) or 60-Hz (16.67 ms) power-frequency clock would be assigned the va ...

cntpPeersRootDelay

A signed fixed-point number indicating the total round-trip delay in seconds, from the peer to the primary reference source at the root of the synchronization subnet.

cntpPeersRootDispersion

The maximum error in seconds, of the peer clock relative to the primary reference source at the root of the synchronization subnet. Only positive values greater than zero are possible.

cntpPeersRefId

The reference identifier of the peer.

cntpPeersRefTime

The local time at the peer when its clock was last updated. If the peer clock has never been synchronized, the value is zero.

cntpPeersOrgTime

The local time at the peer, when its latest NTP message was sent. If the peer becomes unreachable the value is set to zero.

cntpPeersReceiveTime

The local time, when the latest NTP message from the peer arrived. If the peer becomes unreachable the value is set to zero.

cntpPeersTransmitTime

The local time at which the NTP message departed the sender.

cntpPeersUpdateTime

The local time, when the most recent NTP message was received from the peer that was used to calculate the skew dispersion. This represents only the 32-bit integer part of the NTPTimestamp.

cntpPeersReach

A shift register of used to determine the reachability status of the peer, with bits entering from the least significant (rightmost) end. A peer is considered reachable if at least one bit in this register is set to one i.e, if the value of this object i ...

cntpPeersTimer

The interval in seconds, between transmitted NTP messages from the local host to the peer.

cntpPeersOffset

The estimated offset of the peer clock relative to the local clock, in seconds. The host determines the value of this object using the NTP clock-filter algorithm.

cntpPeersDelay

The estimated round-trip delay of the peer clock relative to the local clock over the network path between them, in seconds. The host determines the value of this object using the NTP clock-filter algorithm.

cntpPeersDispersion

The estimated maximum error of the peer clock relative to the local clock over the network path between them, in seconds. The host determines the value of this object using the NTP clock-filter algorithm.

cntpPeersFilterValidEntries

The number of valid entries for a peer in the Filter Register Table. Since, the Filter Register Table is optional, this object will have a value 0 if the Filter Register Table is not implemented.

cntpPeersEntryStatus

The status object for this row. When a management station is creating a new row, it should set the value for cntpPeersPeerAddress at least, before the row can be made active(1).

cntpPeersUpdateTimeRev1

The local time, when the most recent NTP message was received from the peer that was used to calculate the skew dispersion. This represents only the 32-bit integer part of the NTPTimestamp.

cntpPeersPrefPeer

This object specifies whether this peer is the preferred one over the others. By default, when the value of this object is 'false', NTP chooses the peer with which to synchronize the time on the local system. If this object is set to 'true', NTP will choo ...

cntpPeersPeerType

Represents the type of the corresponding instance of cntpPeersPeerName object.

cntpPeersPeerName

The address of the peer. When creating a new association, a value must be set for either this object or the corresponding instance of cntpPeersPeerAddress object, before the row is made active.

cntpFilterRegisterTable

The following table contains NTP state variables used by the NTP clock filter and selection algorithms. This table depicts a shift register. Each stage in the shift register is a 3-tuple consisting of the measured clock offset, measured clock delay and m ...

cntpFilterRegisterEntry

Each entry corresponds to one stage of the shift register, i.e., one reading of the variables clock delay, clock offset and clock dispersion. Entries are automatically created whenever a peer is configured and deleted when the peer is removed.

cntpFilterIndex

An integer value in the specified range that is used to index into the table. The size of the table is fixed at 8. Each entry identifies a particular reading of the clock filter variables in the shift register. Entries are added starting at index 1. Th ...

cntpFilterPeersOffset

The offset of the peer clock relative to the local clock in seconds.

cntpFilterPeersDelay

Round-trip delay of the peer clock relative to the local clock over the network path between them, in seconds. This variable can take on both positive and negative values, depending on clock precision and skew-error accumulation.

cntpFilterPeersDispersion

The maximum error of the peer clock relative to the local clock over the network path between them, in seconds. Only positive values greater than zero are possible.
