How to configure the network equipment to receive time service
NTP protocol is an international standard protocol. The network equipment of many
manufacturers can receive NTP protocol to adjust their own time. For example, the routers of
Cisco, Avaya, Ascend and Huawei can all receive NTP services. Some series switches also
support the NTP protocol. For instance, the configuration command of Cisco router is:
ntp server <IP address>
Regarding the specific configuration, please refer to the manual provided by the
manufacturers. To unify the network time by NTP protocol can effectively improve the quality
of network service. It can also judge the cause of the malfunction by checking the unified
time Log files when the network goes wrong.
