OBJECT-TYPE

This is an eight-bit integer indicating the stratum level of the local clock, with values defined as follows: 0, unspecified 1, primary reference (e.g.,, radio clock) 2-255, secondary reference (via NTP)

OBJECT-TYPE

Precision : This is a signed integer indicating the precision of the various clocks, 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 (16.67ms) power-frequency clock would be assigned the value -5 (31.25 ms), while a 1000-Hz (1 ms) crystal-controlled clock would be assigned the value -9 (1.95 ms).

OBJECT-TYPE

Root Delay : This is a signed fixed-point number indicating the total roundtrip delay to the primary reference source at the root of the synchronization subnet, in milliseconds. Note that this variable can take on both positive and negative values, depending on clock precision and skew.

Poll Interval : This is a signed integer indicating the minimum interval between transmitted messages, in seconds as a power of two. For instance, a value of six indicates a minimum interval of 64 seconds.

OBJECT-TYPE

This is a selector identifying the current synchronization source. Usually this will be a pointer to a structure containing the peer variables. The special value NULL indicates There is no currently valid synchronization source. hh3cNTPSysPeer is replaced by hh3cNTPSysSrcPeer. Reading hh3cNTPSysPeer might fail because the syntax value range is limited, for example, when the synchronization source IP address is a Class C address.

This is a selector identifying the current synchronization source. Usually this will be a unsigned integer containing the peer variables. The special value 0 indicates There is no currently valid synchronization source. This node will replace hh3cNTPSysPeer, because its value range is unlimited, and data type is changed from Integer32 to Unsigned32.

OBJECT-TYPE

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.

OBJECT-TYPE

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 peers. Similarly entries are deleted when the user removes the peer association from the NTP server. Entries can also be created by the management station by setting values for the following objects: hh3cNTPPeerRemAdr and making the hh3cNTPPeerRowStatus as 'active'. At the least, the management station has to set a value for hh3cNTPPeerRemAdr to make the row active.

This is a two-bit code warning of an impending leap second to be inserted in the NTP timescale. The bits are set before 23:59 on the day of insertion and reset after 00:00 on the following day. This causes the number of seconds (rollover interval) in the day of insertion to be increased or decreased by one. The two bits are coded as below, 00, no warning 01, last minute has 61 seconds 10, last minute has 59 seconds 11, alarm condition (clock not synchronized)

OBJECT-TYPE

This is an integer indicating the association mode, with values coded as follows, 0, unspecified 1, symmetric active - A host operating in this mode sends periodic messages regardless of the reach ability state or stratum of its peer. By operating in this mode the host announces its willingness to synchronize and be synchronized by the peer 2, symmetric passive - This type of association is ordinarily created upon arrival of a message from a peer operating in the symmetric active mode and persists only as long as the peer is reachable and operating at a stratum level less than or equal to the host; otherwise, the association is dissolved. However, the association will always persist until at least one message has been sent in reply. By operating in this mode the host announces its willingness to synchronize and be synchronized by the peer 3, client - A host operating in this mode sends periodic messages regardless of the reach ability state or stratum of its peer. By operating in this mode the host, usually a LAN workstation, announces its willingness to be synchronized by, but not to synchronize the peer 4, server - This type of association is ordinarily created upon arrival of a client request message and exists only in order to reply to that request, after which the association is dissolved.
