Huawei Quidway S5700 Series User Manual

The IP address of the NTP server is configured.
Step 2 is optional. If source-interface is specified in Step 3, use it preferentially.
ip-address is the IP address of the NTP server. It can be the IP address of the host
rather than a broadcast address, a multicast address, or the IP address of the reference
clock.
NOTE
When the unicast NTP server is specified, the local switch functions as the client automatically.
The server needs to be configured with only a primary clock.
l (Optional) Configuring the Source Interface for the NTP Server to Send NTP Packets
Do as follows on the switch working as a client:
1. Run:
system-view
The system view is displayed.
2. Run:
ntp-service source-interface vlanif vlan-id
The local source interface that sends NTP packets is specified.
Commonly, specify the IP address of the NTP server on the client. The client and
server can then exchange NTP packets using this IP address
If the source interface to send NTP packets is specified on the server, the IP address
of the server configured on the client should be the same; otherwise, the client cannot
process NTP packets sent from the server and clock synchronization fails.
----End
4.3.4 Configuring the Peer Mode
This part describes how to configure the NTP peer mode. In this mode, clocks on the two peers
synchronize with each other. Each side can send the clock synchronization request message to
the peer and reply the clock synchronization request message from the peer.
Procedure
