.1.3.6.1.4.1.9.9.168.1.1.3 |
|
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

| cntpPeersVarEntry |
.1.3.6.1.4.1.9.9.168.1.2.1.1 |
|
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:
cntpPeersPeerAddress or cntpPeersPeerName,
cntpPeersHostAddress and
cntpPeersMode and making the cntpPeersEntryStatus as
active(1). At the least, the management station has
to set a value for cntpPeersPeerAddress or
cntpPeersPeerName to make the row active.
|
| cntpFilterRegisterEntry |
.1.3.6.1.4.1.9.9.168.1.3.2.1 |

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.

|
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 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
reachability 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. By operating in this mode the host,
usually a LAN time server, announces its
willingness to synchronize, but not to be
synchronized by the peer
5, broadcast - A host operating in this mode sends
periodic messages regardless of the
reachability state or stratum of the peers.
By operating in this mode the host, usually a
LAN time server operating on a high-speed
broadcast medium, announces its willingness to
synchronize all of the peers, but not to be
synchronized by any of them
6, reserved for NTP control messages
7, reserved for private use.
When creating a new peer association, if no value
is specified for this object, it defaults to
symmetricActive(1).

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 choose the corresponding
peer to synchronize the time with. If multiple
entries have this object set to 'true', NTP will
choose the first one to be set. This object is
a means to override the selection of the peer by
NTP.
