Synchronization between Management and Standby Units
Data between the Management and Standby units is synchronized immediately after bootup.
After the Management and Standby units have done an initial full synchronization (block sync), Dell Networking OS only
updates changed data (incremental sync). The data that is synchronized consists of configuration data, operational data, state
and status, and statistics depending on the Dell Networking OS version.
