This is the standard SMIv2 RowStatus column used to create, activate, or delete this specific route table entry, though the MIB notes notInService and notReady are not actually supported states on this implementation. Because two of the six standard RowStatus states are not implemented here, an admin scripting route provisioning against this MIB can really only rely on createAndGo, active, and destroy in practice, since trying to leverage the staged notInService or notReady workflow that works on other RowStatus-based tables would not behave as expected on this modem. Setting this to createAndGo(4) while also populating the destination address, mask, and next-hop objects in the same SNMP request would create and immediately activate a new route in one step, since the staged workflow is not available here.
