This read-write INTEGER object controls adding, deleting, or modifying an entry for a CAS variant using createAndGo (requires vismCasVariantName and vismCasFileName to be set), active (returned once created), and destroy. This is the standard row-creation control object for the CAS variant table, gating whether the file download and state machine initialization process begins. An engineer provisioning a new CAS variant would set this to createAndGo only after also specifying the variant name and file name in the same SNMP request.
