Monitoring PPP Interfaces
Use the following versions of the show ppp interface command to monitor PPP interfaces:
You can set a statistics baseline for PPP interfaces using the baseline ppp commands. Use the optional delta keyword with PPP show commands to show baselined statistics.
You can use the output filtering feature of the show command to include or exclude lines of output based on a text string that you specify. Refer to show Commands in JUNOSe System Basics Configuration Guide, Chapter 2, Command-Line Interface, for details.
baseline ppp interface
- Use to establish a baseline for PPP statistics on an interface.
- The router implements the baseline by reading and storing the statistics at the time the baseline is set, then subtracting this baseline whenever baseline-related statistics are retrieved.
- Use the optional delta keyword with PPP show commands to show baselined statistics.
- Examples
host1#baseline ppp interface atm 3/3.20
host1#baseline ppp interface atm 3/0/3.20
show ppp interface
- Use to display selective PPP interface information.
- You can filter the command display for characteristics of particular interest, such as interface type, data type, configured protocol, or interface state.
- Field descriptions
- PPP interface—Interface type, interface specifier, and status (up, down, lowerDown, not present, passive, or tunnel). For more information about specifying the physical interface on which you want to configure PPP, see Interface Types and Specifiers in JUNOSe Command Reference Guide, About This Guide.

- If the operational status is down for a specific interface, one of the following termination reasons might appear in parentheses:

- no upper interface—No upper layer is configured. This applies to an interface only.
- authentication failure—Authentication is required and has failed. This applies to an interface only.
- no local xxx—local option, xxx, is required and could not be negotiated (for example, IP address). This applies to an interface, IPCP, IPv6CP, OSINLCP, and MPLS.
- no peer xxx—Remote peer option, xxx, is required and could not be negotiated (for example, authentication). This applies to an interface, IPCP, IPv6CP, OSINLCP, and MPLS.
