cucsSwEthMonFsmDescrData (syntax SnmpAdminString) is the human-readable description text UCSM generated for this SPAN-session FSM instance, summarizing the overall FSM workflow currently tracked against the parent EthMon object. An admin reads this text to get a plain-language status update on the configuration task without having to decode the underlying FSM state machine's numeric or enum codes. For example, if a NetFlow or SPAN configuration change is stuck, this description often names the exact stage the workflow is blocked on, pointing the admin straight at the problem.
