Tracing Operations of the Interface Process
To trace the operations of the router’s interface process, dcd, include the traceoptions statement at the [edit interfaces] hierarchy level:
[edit interfaces]traceoptions {file <filename> <files number> <match regular-expression> <size size> <world-readable |
no-world-readable>;flag flag <disable>;no-remote-trace;}
By default, interface process operations are placed in the file named dcd and three 1-MB files of tracing information are maintained.
You can specify the following flags in the interfaces traceoptions statement:
- change-events—Log changes that produce configuration events.
- config-states—Log the configuration state machine changes.
- kernel—Log configuration IPC messages to kernel.
- kernel-detail—Log details of configuration messages to kernel.
For general information about tracing, see the tracing and logging information in the JUNOS System Basics Configuration Guide.
