Statistics collection

The DDM information and warnings and alarms are collected at one minute intervals, so the minimum resolution for any DDM events when correlating with other system events is one minute.

In the Transceiver Digital Diagnostic Monitoring section of the show port port-id detail command output:


B:SR7-101# show port 2/1/6 detail
