71.3.2 DDMI
The optical SFP transceiver’s support for the Digital Diagnostics Monitoring Interface (DDMI) function lets
you monitor the transceiver’s parameters to perform component monitoring, fault isolation and failure
prediction tasks. This allows proactive, preventative network maintenance to help ensure service
continuity.
Use this screen to view the DDMI status of the Switch’s SFP transceivers. Click Management > Port Status >
DDMI to see the following screen. Alternatively, click Status from any Web Configurator screen and then
the Port Status link in the Quick Links section of the Status screen to display the Port Status screen and
then click the DDMI link tab.
