4.3.5 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 based on the stratum. Each side can send the clock synchronization
request message to the peer and reply the clock synchronization request message from the peer.

Step 2 is optional. If source-interface is specified in Step 3, use it preferentially.
ip-address or ipv6-address is the address of the NTP server. It can be the IPv4 or
IPv6 address of the host other 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.
(Optional) Configuring the Source Interface for the NTP Server to Send NTP Packets
Do as follows on the switch working as a server:
1. Run:
system-view
The system view is displayed.
2. Run:
ntp-service source-interface interface-type interface-number [ vpn-
instance vpn-instance-name
The local source interface that sends NTP packets is specified.
Configuring the NTP Symmetric Active End
1. Run:
system-view
The system view is displayed.
2. (Optional) Run:
ntp-service source-interface source-interface interface-type interface-
number [ vpn-instance vpn-instance-name ]
The local source interface that sends NTP packets is specified.
3. Run:
–
ntp-service unicast-peer ip-address [ version number | authentication-
keyid key-id | source-interface interface-type interface-number |
preference | vpn-instance vpn-instance-name | maxpoll max-number |
minpoll min-number | preempt ] *
The NTP peer with specified IPv4 address is configured.
Step 2 is optional. If source-interface is specified in both Step 2 and Step 3, use the
source interface specified in Step 3 preferentially.
ip-address or ipv6-address is the address of the NTP peer. It can be the IPv4 or
IPv6 address of a host other than a broadcast address, a multicast address, or the IP
address of the reference clock.
