Display Local Server Information
The
ntpinfo
command is used to display information about the local switch’s implementation
of
NTP
. To view local switch
NTP
information, enter the
ntpinfo
command at the system
prompt. A screen similar to the following is shown:
system peer: 0.0.0.0
system peer mode: unspec
leap indicator: 11
stratum: 16
precision: -7
root distance: 0.00000 s
root dispersion: 0.00000 s
reference ID: [0.0.0.0]
reference time: 00000000.00000000 Thu, Feb 7 1936 6:28:16.000
system flags: monitor stats
frequency: 0.000 ppm
stability: 0.000 ppm

Field Descriptions
The following section explains the fields shown using the
ntpinfo
command.
System peer.
The
IP
address of the switch.
System peer mode
. The peer mode of this remote association. There are five possible modes:
symmetric active, symmetric passive, client, server, and broadcast. The displayed mode is
assumed if this association becomes the switch’s host
NTP
server. For a description of the
modes, see Display List of Peers the Server Knows About on page 12-15. For a description of
how to configure a peer, see Configuring a New Peer Association on page 12-12.
Leap indicator
. 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)
Stratum
. The stratum level of the remote peer. If this number is
16
, the remote peer has not
been synchronized.
Precision
. The advertised precision of the switch. It will be a number between -4 and -20.
Root distance
. 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.
Reference ID
. 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-justi-
fied, 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.
