This value is a bit string that indicates which traps
are enabled for the address identified by this entry.
The octet string value is treated as a 64-bit value. The
value is a sum. It initially takes on the value 0, then
for each trap which is enabled, 2 raised to the value of
(a3ComSysAgentTrapDescriptionIndex - 1) for that trap is
added to the sum. A new entry in the table is created by
setting the value of this object for a new destination
address type and destination address. Note that an octet
string of all zeros is not a valid value for this object.
