Troubleshooting PPP Configuration

Symptom 1
PPP authentication always fails, preventing the link from going up.
Solution
This problem may arise if the parameters for authentication are incorrect.
Enable the debugging of PPP, and you can see the information describing that LCP went up upon a
successful LCP negotiation but went down after PAP or CHAP negotiation.
Check the PPP authentication settings at the local and peer ends to make sure that they are consistent.
See the part talking about PPP authentication configuration for reference.
Symptom 2
Physical link is down.
Solution
Check that
The interface has been brought up.
The interface has not been administratively shut down.
LCP negotiation has passed.
Execute the display interface serial command to check the state of the interface. The output
information can be:
serial number is administratively down, line protocol is down
interface is shut down by the administrator.
serial number is down, line protocol is down
or the physical layer has not gone up yet.
Virtual-template number is down, line protocol is spoofing up
interface is a dialer interface and the call establishment attempt has failed.
