Diagnostic Monitoring Interface (DMI)
The following DMI port screen and explanation table contains brief definitions of the
DMI support offered on Transition Networks’ SFP optical interfaces. For further
information, please see the help option on the CPSMM-xxx SNMP agent or Focal
Point, Transition Networks' GUI.
Variable Name
Description
DMI Rx Power
Measured Receive optical power in microwatts and in decibels
relative to 1mW.
DMI Rx Power Alarm Alarm status of measured Receive optical power.
DMI Temp
Internally measured temperature of transceiver in degrees C
and degrees F.
DMI Temp Alarm
Alarm status for internally measured temperature of
transceiver.
DMI Bias Current
Measured transmit bias current in microamperes.
DMI Bias Alarm
Alarm status for measured transmit bias current for the
interface.
DMI Tx Power
Measured transmit power, in microwatts and in decibels
relative to 1mW.
DMI Tx Power Alarm Alarm status of measured transmit power.
Rx Power Intrusion
Threshold
Instructs the converter to stop passing traffic when the receive
power drops below the new threshold. This feature is
sometimes referred to as 'Intrusion Detection,' since tapping
into a fiber to intercept traffic leads to a reduction in receive
power. This value can be entered in microwatts or in decibels
relative to 1mW.
Note:
This feature is not available on all devices.
