3Com 4210G Series Configuration Manual page 1065

In the step above, Switch B and Switch C are configured as symmetric peers, with Switch C in the
symmetric-active mode and Switch B in the symmetric-passive mode. Because the stratus level of
Switch C is 1 while that of Switch B is 3, Switch B is synchronized to Switch C.

[SwitchB] display ntp-service status
Clock status: synchronized
Clock stratum: 2
Reference clock ID: 3.0.1.33
Nominal frequency: 64.0000 Hz
Actual frequency: 64.0000 Hz
Clock precision: 2^7
Clock offset: -21.1982 ms
Root delay: 15.00 ms
Root dispersion: 775.15 ms
Peer dispersion: 34.29 ms
Reference time: 15:22:47.083 UTC Sep 19 2005 (C6D95647.153F7CED)
As shown above, Switch B has been synchronized to Switch C, and the clock stratum level of Switch B
is 2, while that of Switch C is 1.
