RPM Synchronization
Data between the primary (management) and standby RPMs is synchronized immediately after bootup.
After the two RPMs have performed an initial full synchronization (block sync), the system automatically updates only changed data
(incremental sync). The data that is synchronized consists of conguration data, operational data, state and status, and statistics
depending on the version of the Dell Networking OS.
You can manually synchronize the primary and standby RPMs at any time by entering the redundancy synchronize full
command.
