[PPPoE] - Show authentication protocol used

Question:

When connected to a DSL Catalyst 3560X  service provider with a Cisco router using a dialer's basic configuration as follow:

interface Dialer1

ip address negotiated

[OUTPUT_OMITTED]

encapsulation ppp

dialer pool 1

dialer idle-timeout 0

dialer persistent

ppp authentication pap chap callin

ppp chap hostname [OUTPUT_OMITTED]

ppp chap password 0 [OUTPUT_OMITTED]

ppp pap sent-username [OUTPUT_OMITTED] password 0 [OUTPUT_OMITTED]

!

Is there a way to see whcich authentication protocol (PAP, CHAP...) has been used other than running a debug ppp authentication while authenticating ?

Answer:

There is no way beside using debiug command. Note for PPPoE you do not need:

dialer idle-timeout 0
