View DDI Information

About this task

You can view Digital Diagnostic Interface (DDI) information, for example, port information, temperature, and voltages for DDI transceivers.

Note

Transceiver support differs across hardware platforms. For information about supported parts, see the Extreme Optics website.

Procedure

On the Physical Device view, select one or more ports.
In the navigation pane, expand Configuration > Edit > Port.
Select General.
Select the DDI/SFP tab.

PowerOnCounter	Tracks the power-on-life of the part. This value increments by 1 every 48 hours of consecutive power. This value is never decremented or cleared. If you remove or reinsert the part, reset or reboot the chassis, reset the slot, or channelize or dechannelize the port, then the 48-hour time period restarts.
TxDdmInitial	Indicates the Tx dB from low alarm, which is the difference between the TxPower dBm and the TxPower low alarm. The host provides the value after the first 48 consecutive hours of operation.
TxDdmLastGasp	Indicates the last gasp of Tx dB from low alarm. The host updates this value every 48 hours.
RxDdmInitial	Indicates the Rx dB from low alarm, which is the difference between the RxPower dBm and the RxPower low alarm. The host provides the value after the first 48 consecutive hours of operation after a power cycle.
RxDdmLastGasp	Indicates the last gasp of Rx dB from low alarm. The host updates this value every 48 hours.
