dTrapDeviceIndex

Index of table. Traps are sent with this OID followed by the index
number of the table entry that generated the trap. For example, if
the values at index 5 of this table generated a trap, the name of the
trap would be .iso.org.dod.internet.private.enterprises.edsMain.dTrap.
dTrapDeviceTable.dTrapDeviceEntry.dTrapDeviceIndex.5. The numeric
value is 1.3.6.1.4.1.31440.2.2.1.1.5. An integer value is sent with the
trap, which indicates what state change caused the trap. Using the
dTrapDeviceHighThreshold, dTrapDeviceLowThreshold and 
dTrapDeviceHysteresis values, 3 windows are created. Transitions between
these windows generates a trap. The integer value indicates which 
transition caused the trap as follows:
   1 -> middle to high window transition
   2 -> high to middle window transition
   3 -> middle to low window transition
   4 -> low to middle window transition
                 
Note the following when programming traps:
   1) Programming the HighThreshold lower than the LowThreshold is
      invalid and will disable trap generation.
   2) dTrapDeviceHysteresis values are not checked for validity, use them
      with caution.
   3) A trap must be enabled to be sent.
   4) The dTrapDeviceROM must be set to an active device or a trap 
      will not be sent.
   5) The health of the 1-wire device must be greater than 0 or no trap will
      be sent.
   6) The dTrapDeviceVariable must be valid. For exmaple, the DS18S20 has 3
      variables as follows: Temperature, UserByte1 and UserByte2. These are
      numbered 0, 1 and 2 respectively. A setting of 3 or above is invalid.
   7) The dTrapTable must be programmed correctly for traps to be sent.
      The respective table entry must be enabled and have a valid IP address.
      Community strings are not used by the SNMP server.
