Prerequisites
The system clock reference source must be configured.
Context
l
The added system clock source can be used in the system only after it is configured with a
priority.
l
The priority of the clock source takes effect immediately after it is configured. This
operation, however, may cause the clock switching in the system.
l
The system does not determine the quality of the clock source. Therefore, you need to
configure the clock reference source of high quality with a high priority.
Procedure
l
Run the
clock priority
command to configure the priority of the clock source.
The system supports 10 priorities for the clock reference source. The priorities are
represented in the form of
p0/p1/p2/p3/p4/p5/p6/p7/p8/p9
, in which p0 indicates the highest
priority and p9 indicates the lowest priority. For example, if p0-p9 is set to 3/7/8, it indicates
that the priority of the clock reference source with index 3 is the highest, the priority of the
reference source with index 7 is lower, and the priority of the reference source with index
of 8 is the lowest.
----End
Example
To configure the priority of clock reference source 0 to the highest priority and the priority of
clock reference source 1 to the second highest priority, do as follows:
huawei(config)#
clock priority system 0/1
Clock source priority set succeeded
3.9 Configuring the System Time
This topic describes the feature of the NTP protocol and how to configure NTP time on the
MA5616.
3.9.1 Configuring the NTP Time
Configuring the NTP protocol to keep the time of all devices in the network synchronized, so
that the Context implement various service applications based on universal time, such as the
network management system and the network accounting system.
Context
Introduction to the NTP Protocol:
l
The Network Time Protocol (NTP) is an application layer protocol defined in RFC 1305,
which is used to synchronize the times of the distributed time server and the client. The
RFC defines the structures, arithmetics, entities and protocols used in the implementation
of NTP.
