Data Consistency
EFA ensures that SLX devices have the correct configuration before allowing traffic.
Overview
EFA is the data owner and Single Source of Truth (SSOT) for fabric configuration. The following figure describes how data is rendered consistent among EFA services.
Data consistency overview

North-bound applications invoke REST APIs to perform various operations on EFA. EFA ensures that the operations leave EFA and the fabric in a consistent state.
Limitations
- You cannot use the SLX CLI to configure the entities that are managed by EFA.
- EFA can reconcile only those entities or configurations that it manages.
- EFA cannot modify out-of-band entities or configurations unless they conflict with the configurations that it manages.
