+          <p>[agent] Errors in vacmAccessTable RowStatus handling.
+	  There are problems with the handling of vacmAccessTableStatus 
+	  that cause some SNMP test suites to report errors.
+	  Most notably, erroneous set operations frequently cause "genErr" 
+	  errors to be returned. These "genErr" errors are usually caused 
+	  by badmatch exceptions coming from 
+	  <c>{ok, Row} = snmpa_vacm:get_row(RowIndex)</c> 
+	  if the row does not exist. </p>
+	  <p>The semantics of the RowStatus handling in that table has 
+	  been adjusted to be compliant with the RowStatus
+	  textual description of SNPMv2-TC MIB. </p>
