NTP configuration examples

NTP client/server mode configuration example

Network requirements

Perform the following configurations to synchronize the time between Router B and Router A:

• As shown in Figure 26, the loc

al clock of Router A is to be used as a reference source, with the

stratum level 2.

• Router B operates in client/server mode and Router A is to be used as the NTP server of Router B.

Configuration procedure

1. Set the IP address for each interface as shown in Figure 26. (Details not shown.)

2. Configure Router A:

# Specify the local clock as the reference source, with the stratum level 2.

<RouterA> system-view

[RouterA] ntp-service refclock-master 2

3. Configure Router B:

# Display the NTP status of Router B before clock synchronization.

<RouterB> display ntp-service status

Clock status: unsynchronized

Clock stratum: 16

Reference clock ID: none

Nominal frequency: 64.0000 Hz

Actual frequency: 64.0000 Hz

Clock precision: 2^7

Clock offset: 0.0000 ms

Root delay: 0.00 ms

Peer dispersion: 0.00 ms

Reference time: 00:00:00.000 UTC Jan 1 1900 (00000000.00000000)

# Specify Router A as the NTP server of Router B so that Router B synchronizes to Router A.

<RouterB> system-view

[RouterB] ntp-service unicast-server 1.0.1.11

# Display the NTP status of Router B after clock synchronization.

[RouterB] display ntp-service status
