Flags Config

. This counter lists what flags have been configured for this

NTP

entity. For more

information about setting flags, see Set a System Flag (Auth, Bclient, Monitor, Stats) on page
12-35.

Reference Time

. This is the local time, in timestamp format, when the local clock was last

updated. If the local clock has never been synchronized, the value is zero.

Originate Timestamp

. This is the local time, in timestamp format, of the peer when its last

NTP

message was sent. If the peer becomes unreachable the value is set to zero.

Receive Timestamp

. This is the local time, in timestamp format, when the latest

NTP

message

from the peer arrived. If the peer becomes unreachable the value is set to zero.

Transmit Timestamp

. This is the local time, in timestamp format, when the last

NTP

message

was sent from this association.

Filter delay

.

NTP

comes with various filter routines as part of the algorithm that determines

timestamp information. This field shows the delay in seconds the

NTP

algorithm uses to

correct for delays caused by messages traversing through the NTP filters.

Filter offset

.

NTP

comes with various filter routines as part of the algorithm that determines

timestamp information. This counter indicates the offset of the peer clock relative to the local
clock due to filters.

Filter order

. The order in which

NTP

messages pass through filters.

Delay

. The currently estimated delay of this remote association, in seconds. This number indi-

cates the roundtrip delay of the peer clock relative to the local clock over the network path
between them, in seconds. Note that this variable can take on both positive and negative
values, depending on clock precision and skew-error accumulation. This time is determined
by the

NTP

algorithm.

Offset

. The currently estimated offset of this remote association, in seconds. This counter indi-

cates the offset of the peer clock relative to the local clock. This time is determined by the
NTP algorithm.

Disp

. The currently estimated dispersion of this remote association, in seconds. This counter

indicates 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. This time
is determined by the

NTP

algorithm.
