Monitoring MLPPP
Use the commands in this section to display information about MLPPP interfaces.
You can set a statistics baseline for MLPPP serial (member link) or bundle (multilink) interfaces using the baseline ppp command. Use the delta keyword with the show commands described below to display statistics with the baseline values subtracted.
After you configure multilink PPP, you can use the show ppp interface commands to display configuration and statistics information about MLPPP and MLPPP fragmentation and reassembly.
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. For details, see show Commands in JUNOSe System Basics Configuration Guide, Chapter 2, Command-Line Interface.
baseline ppp interface
- Use to set a statistics baseline for PPP interfaces—including MLPPP interfaces, either individual serial (member link) interfaces or multilink (bundle) interfaces.
- Use only the serial or mlppp keywords.
- For serial interfaces, specify the interface location in the format slot/port:channel/subchannel for CT3 modules.
- For MLPPP interfaces, specify the interface location as the name of the MLPPP bundle.
- 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.
- 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 was not set, the following message is displayed instead:
No baseline has been set
host1#baseline ppp interface serial 2/0:1/1
