Root Cause:

    When performing a sync config to the peer, a clear config is triggered, 

    causing some values in the monitor system to be reset to their defaults. 

    However, since the peer side does not have corresponding settings, 

    this results in inconsistencies between the two sides.
Solution:

    When performing a sync config, do not reset the monitor system values to their defaults; 

    instead, wait to apply the settings from the peer side.

synconfig to/from <peer>
Type show synconfig diff <peer> to check there is no diff config.
