Monitoring a PPP Session
You can monitor PPP packet exchanges. When monitoring is enabled, packets exchanged during a session are logged by default to /var/log/pppd, or to the file specified in the traceoptions statement.
To configure PPP packet monitoring, include the monitor-session statement at the [edit protocols ppp] hierarchy level:
[edit protocols ppp]monitor-session (interface-name | all);
When monitoring is configured, the operational mode commands show ppp summary and show ppp interface display a Monitored flag in the Session flags column or line.
