Configure Routing Protocol Process Tracing

Action

To configure routing protocol process (rpd) tracing, follow these steps:

  1. In configuration mode, go to the following hierarchy level:
    [edit]user@host# edit routing-options traceoptions
  2. Configure the file, file size, number, and flags:
    [edit routing-options traceoptions]user@host# set file filename size size file number [edit routing-options traceoptions]user@host# set flag flag

    For example:

    [edit routing-options traceoptions]user@host# set file daemonlog size 10240 files 10 [edit routing-options traceoptions]user@host# set flag general
  3. Verify the configuration:
    user@host# show

    For example:

    [edit routing-options traceoptions]user@host# show file daemonlog size 10k files 10;flag general;
  4. Commit the configuration:
    user@host# commit

Note: Some traceoptions flags generate an extensive amount of information. Tracing can also slow down the operation of routing protocols. Delete the traceoptions configuration if you no longer require it.

  1. View the contents of the file containing the detailed messages:
    user@host# run show log filename

    For example:

    [edit routing-options traceoptions]user@pro4-a# run show log daemonlog Sep 17 14:17:31 trace_on: Tracing to "/var/log/daemonlog" startedSep 17 14:17:31 Tracing flags enabled: generalSep 17 14:17:31 inet_routerid_notify: Router ID: 10.255.245.44Sep 17 14:17:31 inet_routerid_notify: No Router ID assignedSep 17 14:17:31 Initializing LSI globalsSep 17 14:17:31 LSI initialization completeSep 17 14:17:31 Initializing OSPF instancesSep 17 14:17:31 Reinitializing OSPFv2 instance masterSep 17 14:17:31 OSPFv2 instance master running[...Output truncated...]
