The conceptual row of the system Connection table. A row in this table can NOT be created. A row in this table can be modified by providing valid values for one or more writable columns and by setting the value of sysCmdStatus to 'update'. A row in this table can be deleted by setting the value of sysCmdStatus to 'delete'. The sysCmdStatus field must be included as a variable in a SET PDU for the action to take effect. If the sysCmdStatus is missing from the SET PDU, the GET RESPONSE will contain the SNMP error status of 'genErr' for and an error index equal to the last variable.
