monitor list

Start displaying the system log or trace file and additional entries being added to those files.

monitor start

Stop displaying the system log or trace file.

monitor stop

Monitor packet headers transmitted through network interfaces sent from or received by the Routing Engine.

monitor traffic

Display trace information about an IP multicast path.

mtrace

Display trace information about a IP multicast path from a source to the router.
