Troubleshooting DSL Connections
Link State :
• Verify that the DSL link is established (status LED is continuously on)
PPPoE access:
• Check if "show pppoe detail 3" shows "State: .... opened". This indicates that the PVC is valid and a that
you reached a PPPoE server through it.
• Check if "show ppp networks detail 3" shows "State: .... opened" for both the "LCP" and the "CHAP" sec-
tion. If LCP is not working, there is probably no compatible authentication protocol configured. Make sure
"authentication chap" and "authentication pap" are included in the subscriber setup. If only CHAP failed
there may be an error with the username or password.
• Run the “debug” command: node# debug dsl-setup (See table 11 above).
