1.8.2 Configuring NTP Symmetric Peer Mode

I. Network requirements
The local clock of Device A is set as the NTP master clock, with the clock stratum
level of 2.
Device C (an S5100-SI/EI Ethernet switch) uses Device A as the NTP server, and
Device A works in server mode automatically.
The local clock of Device B is set as the NTP master clock, with the clock stratum
level of 1. Set Device C as the peer of Device B.
