Description
This table holds all the currently-raised alarms.
When an alarm is raised, it appears as a new entry in
the table. When an alarm is cleared, it is removed
from the table and all the subsequent entries move
up by one row.
This variable uniquely identifies each entry in an
alarm table. When an alarm in the alarm table clears,
the alarm indexes change for each alarm located
subsequent to the cleared alarm.
This variable provides the entity type that raised the
alarm. The NMS should use this value to decide
which table to poll for further information about the
alarm.
This variable indicates the slot of the object that
raised the alarm. If a slot is not relevant to the alarm,
the slot number is zero.
This variable provides the port of the object that
raised the alarm. If a port is not relevant to the
alarm, the port number is zero.
This variable provides the object line that raised the
alarm. If a line is not relevant to the alarm, the line
number is zero.
Every alarm is raised by an object entry in a specific
table. This variable is the index of the objects in
each table; if the alarm is interface related, this is
the index of the interfaces in the interface table.
This variable provides the exact alarm type.
This variable specifies alarm severity and
service-affecting status. Severities are minor, major
and critical. Service- affecting statuses are
service-affecting and non-service affecting.
This variable gives the time when the alarm
occurred. The value is the number of the ticks that
has lapsed since 1/1/1970.
