In the symmetric peer mode, the local S5500-EI Ethernet switch serves as the symmetric-active peer 
and sends clock synchronization request first, while the remote server serves as the symmetric-passive 
peer automatically. 
If both of the peers have reference clocks, the one with a smaller stratum number is adopted.
