show ntp servers
show rft servers [brief]
Description
Show information for Network TIme Protocol (NTP) servers.
Syntax
Example
The following example shows values for the primary and backup NTP servers. The primary server is marked with
an asterisk (*) and the backup server is marked with an equals sign (=). Note that a backup server will not display
delay, offset or dispersion data, as it is not currently in use.
The output of this command includes the following parameters:
Related Commands
To configure an NTP server, use the command ntp server.
Command History
This command was available in ArubaOS 3.0.
Parameter Description
brief Display only the IP address of the defined NTP servers.
Parameter Description
remote IP address of the remote NTP server defined using the cli command ntp server.
local IP address of the local clock.
st NTP uses hierarchical levels of clock sources, or strata, and assigns each layer a number
starting with zero at the root. The st column in the output of this command represents the
number of servers between the configured NTP server and the root reference clock.
poll Interval, in seconds, between the local NTP server’s attempt to poll the remote NTP server.
reach An index that measures whether or not the remote NTP server could be reached at eight
most recent polling intervals. If the NTP server has just been configured and hasn’t yet
been polled successfully, the value will be zero (0). A value of 377 indicates that the last
eight poll queries were successful.
delay Delay, in seconds, between the time that the local clock polls the NTP server and the NTP
server returns a reply.
offset The difference in time, in seconds, between the local clock and the NTP server.
disp Dispersion represents the maximum error of the local clock relative to the reference clock,
and is a measurement of the time server and network quality. Lower dispersion values are
preferred over higher dispersion values.
