JUNOS : Configure System Log

By default, control protocol activity is logged as a separate system log facility, dfc. To modify the filename or level at which control protocol activity is recorded, include the following statements at the [edit syslog] hierarchy level:

[edit syslog]

file dfc.log {dfc any;}

To cancel logging, include the no-syslog statement at the [edit services dynamic-flow-capture capture-group client-name control-source identifier] hierarchy level:

[edit services dynamic-flow-capture capture-group client-name control-source identifier]no-syslog;
