S2600E CLI Reference Guide Chapter 3 NTP Configuration Commands
Usage
guidelines
In general, the local system synchronizes the time from the
external time source directly or indirectly. However, if the
time synchronization of local system fails for the network
connection trouble, ect, use the command to set the
reliable reference source of the local time, providing the
synchronized time for other devices.
Once set, the system time can not be synchronized to the
time source with higher starum.
Caution:
Using this command to set the local time as the master (in
particular, specify a lower starum value), is likely to be
covered by the effective clock source. If multiple devices in
the same network use this command, the time
synchronization instability may occur due to the time
difference between the devices.
In addition, before using this command, if the system has
never been synchronized with an external clock source, it
is necessary to manually calibrate the system clock to
prevent too much bias.
Examples
The configuration example below configures the reliable
local time reference source and set the time stratum 12:
Ruijie(config)# ntp master 12
3.1.7 ntp server
Use this command to specify a NTP server for the NTP client.
ntp server ip-addr [ version version ] [ source if-name ] [ key keyid ][ prefer ]
no ntp server ip-addr
Parameter Description
ip-addr Set the IP address of the NTP server.
version
(Optional) Specify the version (1-3) of
NTP, NTPv3 by default.
if-name
(Optional) Specify the source interface
from which the NTP message is sent
(L3 interface).
Parameter
