The following example illustrates an XKL-specific MIB object and related trap.
The sensor temperature object xklSensorTemp shows the temperature at the sensor in degrees Celsius, as a 32-bit read-only
value:
xklSensorTemp OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Temperature of the sensor (Celsius)"
::= { xklSensorEntry 3 }
The trap
xklTempStatusChange
notifies a sensor temperature change event. Note that this trap can be triggered by any
of the sensor objects

OBJECTS { xklSensorIndex, xklSensorDescription, xklSensorTemp, xklSensorSta-
tus }
STATUS current
DESCRIPTION
"Temperature status has changed"
::= { xklProTraps 6 }
3.3.5 Error Detection
Error detection at optical frequencies is at the physical layer of the network stack. DarkStar systems rely on signal integrity
indicators from the laser interfaces and Clock and Data Recovery (CDR) circuitry to monitor and detect signal errors.
The most common indicators used to monitor the integrity of incoming optical signals, in order of precedence, are:
• Loss of Signal (LOS): The optical power of a receive-direction optical signal is reported by the laser module receiver. When
