Step 1: Configure Routing Protocol Process Tracing
Action
To configure routing protocol process (rpd) tracing, follow these steps:
- In configuration mode, go to the following hierarchy level:
[edit]
user@host# edit routing-options traceoptions
- Configure the file, file size, number, and flags:
[edit routing-options traceoptions]
user@host# set file filename size size files 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
- Verify the configuration:
user@host# show
For example:
[edit routing-options traceoptions]
user@host# show
file daemonlog size 10k files 10;
flag general;
- 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. |
- 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
