Display Sent or Received IS-IS Protocol Packets

Action

To configure the tracing for only sent or received IS-IS protocol packets, follow these steps:

  1. In configuration mode, go to the following hierarchy level:
    [edit]user@host# edit protocol isis traceoptions
  2. Configure the flag to display sent, received, or both sent and received packets:
    [edit protocols isis traceoptions]user@host# set flag hello send

    or

    [edit protocols isis traceoptions]user@host# set flag hello receive

    or

    [edit protocols isis traceoptions]user@host# set flag hello
  3. Verify the configuration:
    user@host# show

    For example:

    [edit protocols isis traceoptions]
    user@host# show 
    file isislog size 10k files 10;
    flag hello send;

    or

    [edit protocols isis traceoptions]
    user@host# show 
    file isislog size 10k files 10;
    flag hello receive;

    or

    [edit protocols isis traceoptions]
    user@host# show 
    file isislog size 10k files 10;
    flag hello send receive;
  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:

    user@host# run show log isislog
