NTP symmetric peers mode configuration example
Network requirements
•
As shown in
, configure Device A as a reference source, with the stratum level 2.
•
Configure Device B to operate in client mode and use Device A as its NTP server.
•
Configure Device C to operate in symmetric-active mode and use Device B as its symmetric-passive
peer.
