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 conguration data, operational data, state and status, and statistics
depending on the Dell Networking OS version.
