Precision
. The advertised precision of this association, which is a number from -4 to -20. For
information on setting the advertised precision, see Configuring an NTP Client on page 12-6
and Set the Server’s Advertised Precision on page 12-14.
Leap
. The status of leap second insertion for this association. Leap seconds are seconds that
are added to the timestamp of an
NTP
entity to correct accumulated time errors. The possible
values are:
00
No warning.
01
Last minute has 61 seconds.
10
Last minute has 59 seconds.
11
Alarm condition (clock not synchronized).
Refid
. This is a 32-bit code identifying the particular reference clock. In the case of stratum 0
(unspecified) or stratum 1 (primary reference source), this is a four-octet, left-justified, zero-
padded
ASCII
string. In the case of stratum 2 and greater (secondary reference) this is the
four-octet Internet address of the peer selected for synchronization.
Rootdistance
. 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 seconds. Note that this
variable can take on both positive and negative values, depending on clock precision and
skew.
Rootdispersion
. This is a signed fixed-point number indicating the maximum error relative to
the primary reference source at the root of the synchronization subnet, in seconds. Only posi-
tive values are possible.
Ppoll
. The poll time for this association when it is a peer. This number is the minimum inter-
val between transmitted messages, in seconds as a power of two. For instance, a value of six
indicates a minimum interval of 64 seconds.
Hpoll
. The poll time for this association when it is a host. This number is the minimum inter-
val between transmitted messages, in seconds as a power of two. For instance, a value of six
indicates a minimum interval of 64 seconds.
KeyID
. This is an integer identifying the cryptographic key used to generate the message
authentication code.
Version
. The version of
NTP
this association is using; the options are
1
,
2
, or
3
.
Association
. The number of seconds since this
NTP
entity was associated with the switch.
Valid
. This is an integer counter indicating the valid samples remaining in the filter register. It
is used to determine the reachability state of an association, and when the poll interval should
be increased or decreased.
Reach
. This is a shift register used to determine the reachability status of this peer. The
NTP
algorithm uses this when determining timestamp information.
Unreach
. The number of times this
NTP
entity was unreachable.
Flash
. This field displays the number of error bits from the packet procedure.
Boffset
. This field displays the default broadcast delay in seconds.
TTL/mode
. This fields displays the Time-to-Live (
TTL
) time in seconds and the mode (unicast,
multicast, or broadcast) of
NTP
messages sent to a broadcast address. For information on
configuring an
NTP
broadcast address, see Configuring a Broadcast Time Service on page 12-
13.
Timer
. Shows the number of seconds until the next
NTP
message is sent to an association.
