Entries appear in this table when there are variables in
the varbind list of a corresponding alarm in
alarmActiveTable.
Entries appear in this table as though
the trap/notification had been transported using a
SNMPv2-Trap-PDU, as defined in [RFC3416] - i.e., the
alarmActiveVariableIndex 1 will always be sysUpTime
and alarmActiveVariableIndex 2 will always be
snmpTrapOID.
If the incoming notification is instead an SNMPv1 Trap-PDU and
the value of alarmModelVarbindIndex is 1 or 2, an appropriate
value for sysUpTime.0 or snmpTrapOID.0 shall be determined
by using the rules in section 3.1 of [RFC3584].
