Trace Action

If you specify the trace action, the match is logged to a trace file. To set up a trace file, you must specify the following elements in the global traceoptions statement:

• Trace filename
• policy option in the flag statement

For more information about the global traceoptions statement, see the JUNOS Routing Protocols Configuration Guide.

The following example uses the trace filename of policy-log:

[edit]

routing-options {

    traceoptions {

        file "policy-log";

        flag policy;

    }

}

This action does not affect the flow control during routing policy evaluation.

If a term that specifies a trace action also specifies a flow control action, the name of the term will be logged in the trace file. If a term specifies a trace action only, the word <default> only will be logged.
