# ETSI TS 103264 Clause 5.9: Commands and device commands

## In SAREF, commands represent the lowest-level directives a device supports and exposes to some network. Commands can act upon (OP saref:actsUpon and its sub-properties) features, properties, or states. While commands are independent of any function, commands of interest are commands actually supported by a function of interest.

# ETSI TS 103264 Clause 5.9.2: Commands
