Junos OS

Hello everyone,

I'm transitioning from Huawei to Juniper devices and am looking for a command equivalent to Huawei's display aaa online-fail reason on Juniper routers.

On Huawei devices, the display aaa online-fail reason command provides detailed information on why authentication attempts, such as PPPoE, are failing (e.g., wrong username/password, authentication server unreachable, etc.). This is particularly useful when troubleshooting connectivity issues related to subscriber authentication failures.

Is there a Juniper command that provides a similar level of detail about failed authentication attempts, particularly for PPPoE connections? I've tried some basic commands like show pppoe sessions extensive and checking the logs with show log messages | match ppp, but I am specifically looking for a command that directly shows the failure reasons, such as invalid credentials or protocol mismatches.

Any advice or guidance would be greatly appreciated!

Thanks in advance!

Hi Igor,

Have you tried 'show pppoe statistics' command? Also, you can refer to this guide, there are quite a few commands listed here which can help you to troubleshoot PPPoE sessions.
