Parameters
|
: Filters command output by specifying a regular expression. For more information about regular
expressions, see Fundamentals Configuration Guide.
begin
: Displays the first line that matches the specified regular expression and all lines that follow.
exclude
: Displays all lines that do not match the specified regular expression.
include
: Displays all lines that match the specified regular expression.
regular-expression
: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Description
Use
display ntp-service trace
to display brief information about each NTP server from the local device
back to the primary reference source.
The
display ntp-service trace
command takes effect only when the local device and all the devices on the
NTP server chain can reach one another. Otherwise, this command is unable to display all the NTP
servers on the NTP chain due to timeout.
Examples
# Display brief information about each NTP server from the local device back to the primary reference
source.
<Sysname> display ntp-service trace
server 127.0.0.1,stratum 2, offset -0.013500, synch distance 0.03154
server 133.1.1.1,stratum 1, offset -0.506500, synch distance 0.03429
refid LOCL
The output shows an NTP server chain for server 127.0.0.1: Server 127.0.0.1 is synchronized to server
133.1.1.1, and server 133.1.1.1 is synchronized to the local clock source.
Table 6
Command output
Field
Description
server
IP address of the NTP server.
stratum
Stratum level of the corresponding system clock.
offset
Clock offset relative to the upper-level clock, in seconds.
synch distance
Synchronization distance relative to the upper-level clock, in
seconds, and calculated from dispersion and roundtrip delay
values.
refid
Identifier of the primary reference source. When the stratum level of
the primary reference clock is 0, it is displayed as
LOCL
. Otherwise,
it is displayed as the IP address of the primary reference clock.
