We enable DCD traceoptions to trace the operations of the router or switch interface process. DCD traceoptions can help to understand interface related problems.

Not Applicable

Under main hierarchy:

set interfaces traceoptions file <filename>

set interfaces traceoptions file size <size of the file>

set interfaces traceoptions file files <number of files>

set interfaces traceoptions flag <all or specific flag>

set interfaces traceoptions flag verbose // Log DCD debug all events

Example

set interfaces traceoptions file dcd

set interfaces traceoptions file size 500m

set interfaces traceoptions file files 20

set interfaces traceoptions flag all

set interfaces traceoptions flag verbose

We can enable this under group hierarchy as well.

Example:

[edit groups <group-name> interfaces traceoptions]
