Configure Routing Protocol Tracing for a Specific Routing Protocol

Action

To configure routing protocol tracing for a specific routing protocol, follow these steps:

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

    For example:

    [edit protocols ospf traceoptions]user@host# set file ospflog size 10240 files 10 [edit protocols ospf traceoptions]user@host# set flag general
  3. Verify the configuration:
    user@host# show

    For example:

    [edit protocols ospf traceoptions]user@host# show file ospflog size 10k files 10;flag general;
  4. Commit the configuration:
    user@host# commit
  5. View the contents of the file containing the detailed messages:
    user@host# run show log filename

    For example:

    [edit protocols ospf traceoptions]user@pro4-a# run show log ospflog Sep 17 14:23:10 trace_on: Tracing to "/var/log/ospflog" startedSep 17 14:23:10 rt_flash_update_callback: flash OSPF (inet.0) startSep 17 14:23:10 OSPF: multicast address 224.0.0.5/32, route ignoredSep 17 14:23:10 rt_flash_update_callback: flash OSPF (inet.0) doneSep 17 14:23:10 CHANGE 10.255.245.46/32 gw 10.10.208.67 OSPF pref 10/0 metric 1/0 fe-0/0/0.0 <Delete Int>Sep 17 14:23:10 CHANGE 10.255.245.46/32 gw 10.10.208.67 OSPF pref 10/0 metric 1/0 fe-0/0/0.0 <Active Int>Sep 17 14:23:10 ADD 10.255.245.46/32 gw 10.10.208.67 OSPF pref 10/0 metric 1/0 fe-0/0/0.0 <Active Int>Sep 17 14:23:10 CHANGE 10.255.245.48/32 gw 10.10.208.69 OSPF pref 10/0 metric 1/0 fe-0/0/0.0 <Delete Int>Sep 17 14:23:10 CHANGE 10.255.245.48/32 gw 10.10.208.69 OSPF pref 10/0 metric 1/0 fe-0/0/0.0 <Active Int>Sep 17 14:23:10 ADD 10.255.245.48/32 gw 10.10.208.69 OSPF pref 10/0 metric 1/0 fe-0/0/0.0 <Active Int>Sep 17 14:23:10 rt_close: 4/4 routes proto OSPF[...Output truncated...]

Meaning
