Ntp Server Mode With Authentication Configuration - Huawei Quidway S3900 Series Operation Manual

Operation Manual -- NTP
Quidway S3900 Series Ethernet Switches-Release 1510
# Enter VLAN-interface 2 view.
[[S3900-2] interface Vlan-interface 2
# Configure S3900-2 to be a multicast client.
[S3900-2-Vlan-interface2] ntp-service multicast-client
The above configuration configures S3900-1 and S3900-2 to listen to multicast packets
through their VLAN interface 2, and Quidway3 to advertise multicast packets through
VLAN interface 2. Because S3900-2 does not reside in the same network segment with
Quidway3, S3900-2 cannot receive multicast packets sent by Quidway3, while
S3900-1 is synchronized to Quidway3 after receiving multicast packets sent by
Quidway3.
