DDMI (Digital Diagnostics Monitoring Interface)
DDMI (Digital Diagnostics Monitoring Interface) provides enhanced digital DMI for optical transceivers which
allows real time access to device operating parameters.
The following DMI port screen and explanation table contains brief definitions of the DDMI support offered on
some Small Form Factor Pluggable (SFP) Transceiver Modules. For further information, see the help option or
User Guide for the relate product4.
Note:
This feature is not available on all devices and may vary between
products. See the related manual for more information.
The Transceiver Information and DDMI Information sections are described below.
DDMI Parameter
Description
DMI
Rx Power (uW) Intrusion Threshold; a level for Rx Power on the Fiber port. If the DMI
read value falls below the preset value, an intrusion is detected, and a trap is
generated. The default is 0 uW. The range is 0 - 65,535 uW.
Port
The device’s port number.
Vendor
The SFP vendor’s name (e.g.,
Transition
).
Part
Number
The SFP vendor Part number provided by the SFP vendor (
TN-10GSFP-SR
).
Serial
Number
The SFP Vendor Serial number provided by the SFP vendor (e.g.,
8672105
).
Revision
The SFP vendor Revision level for part number provided by the SFP vendor.
Date
Code
The vendor's manufacturing date code (e.g
., 2011-08-09
).
Transeiver
The Transceiver compatibility (e.g.,
1000BASE_SX
or
10G
).
Current
The current value of temperature, voltage, TX bias, TX power, and RX power.
High Alarm Threshold
The high alarm threshold value - temperature, voltage, TX bias, TX power, - RX power.
High Warn Threshold
The high warn threshold value of temperature, voltage, TX bias, TX power, RX power.
Low Warn Threshold
The low warn threshold value of temperature, voltage, TX bias, TX power, RX power.
Low Alarm Threshold
The low alarm threshold value - temperature, voltage, TX bias, TX power, RX power.
