RPM synchronization Data between the two RPMs is synchronized immediately after bootup. Once the two RPMs have done an initial full synchronization (block sync), thereafter FTOS 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 FTOS version. Failover Type Warm Failover Synchronized Data some NVRAM information, startup-configuration, line card configurations, user-access configurations Platform ec s Hot Failover some NVRAM information, startup-config, line card configurations, user-access configurations, running-config, SFM and datapath states, run-time event log and configuration, interface state ec s RPM redundancy configuration tasks Select a Primary RPM The RPM in slot 0 is the primary RPM by default.
