Monitoring PPPoE
Use the commands described in this section to display information about PPPoE interfaces and subinterfaces.
You can set a statistics baseline for PPPoE interfaces, subinterfaces, and/or circuits using the baseline pppoe interface command.
You can use the output filtering feature of the show command to include or exclude lines of output based on a text string you specify. See JUNOSe System Basics Configuration Guide, Chapter 2, Command-Line Interface for details.
baseline pppoe interface
- Use to set a statistics baseline for PPPoE interfaces, subinterfaces, and circuits.
- The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
- You cannot set a baseline for groups of interfaces, subinterfaces, or circuits. You must set them one at a time.
- When baselining is requested, the time since the last baseline was set is displayed in hours:minutes:seconds or days/hours format. If a baseline has not been set, the message "No baseline has been set" is displayed instead.
- Use the optional delta keyword with PPPoE show commands to specify that baselined statistics will be shown.
- Examples
host1#baseline pppoe interface atm 2/0.1.1
host1#baseline pppoe interface atm 2/0/0.1.1
