Fault 1: The link never turns into the up state.
Problem solving: This problem may arise from the PPP authentication failure due to the
incorrect configuration of PPP authentication parameters.
Enable the debugging of PPP, and you will see the information describing that LCP
went up with a successful LCP negotiation but went down after the PAP or CHAP
negotiation.
Fault 2: The physical link fails to go up.
Problem solving: Execute the display interface type number command to view the
current interface status.
