Operation Manual – NTPH3C S3610&S5510 Series Ethernet Switches Chapter 1 NTP Configuration1-20II. Network diagramFigure 1-8 Network diagram for NTP symmetric peers mode configurationIII. Configuration procedure1) Configuration on Device A:# Specify the local clock as the reference source, with the stratum level of 2. system-view[DeviceA] ntp-service refclock-master 22) Configuration on Device B:# Specify Device A as the NTP server of Device B. system-view[DeviceB] ntp-service unicast-server 3.0.1.313) Configuration on Device C (after Device B is synchronized to Device A):# Specify the local clock as the reference source, with the stratum level of 1. system-view[DeviceC] ntp-service refclock-master 1# Configure Device B as a symmetric peer after local synchronization.[DeviceC] ntp-service unicast-peer 3.0.1.32In the step above, Device B and Device C are configured as symmetric peers, withDevice C in the symmetric-active mode and Device B in the symmetric-passive mode.Because the stratus level of Device C is 1 while that of Device B is 3, Device B issynchronized to Device C.# View the NTP status of Device B after clock synchronization.[DeviceB] display ntp-service statusClock status: synchronizedClock stratum: 2Reference clock ID: 3.0.1.33
