15.2 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 MONITOR > Port Status >
DDMI to see the following screen. Alternatively, click DASHBOARD from any Web Configurator screen
and then the Port Status link in the Quick Link section of the DASHBOARD screen to display the Port Status
screen and then click the DDMI link tab.
