Configuring Ntp Peer Mode - H3C S3600 Series Operation Manual

Operation Manual – NTP
H3C S3600 Series Ethernet Switches-Release 1510

1.7.2 Configuring NTP Peer Mode

I. Network requirements
The local clock of H3C2 is set to the NTP master clock, with the clock stratum level of 2.
An S3600 Ethernet switch considers H3C2 as the NTP server and serves as the client,
while H3C2 operates in server mode automatically. In addition, H3C3 considers the
S3600 Ethernet switch as its peer.
Note:
This example assumes that:
H3C2 is a switch that allows its local clock to be the master clock.
H3C3 is a switch that allows its local clock to be the master clock and the stratum
level of its clock is 1.

III. Configuration procedure
1) Configure the S3600 series switch.
# Set H3C2 to the NTP server.
<S3600> system-view
[S3600] ntp-service unicast-server 3.0.1.31
2) Configure H3C3 (after the S3600 Ethernet switch is synchronized to H3C2).
# Enter system view.
<H3C3> system-view
[H3C3]
# Set the S3600 Ethernet switch to the peer of H3C3.
