Troubleshooting PPP and PPPoE Dynamic Interfaces

You can issue the profile-reassign command to help you use PPP and PPPoE
packet–logging capabilities to debug and troubleshoot PPP and PPPoE dynamic
interfaces. To use the profile-reassign command, you must access Privileged Exec
mode at privilege level 5 or higher.
The profile-reassign command enables you to reassign the profile currently assigned
to the specified encapsulation type for the specified ATM 1483 subinterface. In effect,
you swap the currently assigned nondebug profile for a debug profile that has identical
attributes with the addition of one or more PPP or PPPoE packet–logging attributes
enabled.

Create a debug profile that includes the same attributes as an existing nondebug
profile, with the addition of one or more PPP or PPPoE packet–logging attributes
enabled.
Observe the following guidelines when you create the debug profile:
Because PPP and PPPoE packet logging is performed at log severity 7 (debug
priority), configure a destination such as the console to log severity level 7
and issue the log here command to enable packet capture using the debug
profile you created.
Before you reassign the debug profile to the ATM 1483 subinterface, make
sure that the number of PPP dynamic interfaces has not already exceeded
the maximum number of aggregate dynamic and static PPP interfaces for
which you can log PPP packets. For more information about this and other
system maximums, see JUNOSe Release Notes, Appendix A, System
Maximums.
For details about creating and using profiles, see "Configuring a Dynamic Interface
from a Profile" on page 513.
Access Privileged Exec mode at privilege level 5 or higher.
