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 Hot Failover Synchronized Data some NVRAM information, startup-configuration, line card configurations, user-access configurations 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 Platform ecs ecs RPM redundancy configuration tasks Select a Primary RPM The RPM in slot 0 is the primary RPM by default. Manually select the primary RPM using the command redundancy primary from CONFIGURATION mode. View which RPM is the primary using the command show running-config redundancy from EXEC Privilege mode, as shown in the example in the "Force an RPM failover" section.

Use this feature when: • You are replacing an RPM, and • You are performing a warm upgrade FTOS#redundancy force-failover rpm Peer RPM's SW version is different but HA compatible. Failover can be done by warm or hitless upgrade. All linecards will be reset during warm upgrade.
