PPPOE or PPPOA on an atm0 - 877?

Hi all,

delegating the first configuration to my colleagues and seeing the following:

Current configuration : 173 bytes ! interface ATM0 no ip address no atm ilmi-keepalive pvc 8/35 ubr 160 oam retry 5 5 1 dialer pool-member 1 protocol ppp dialer ! dsl operating-mode auto end


Current configuration : 275 bytes ! interface Dialer0 ip address negotiated ip nat outside ip virtual-reassembly encapsulation ppp dialer pool 1 ppp chap hostname XXXXXXXXXXXX ppp chap password 7 XXXXXXXXXXXXXXXx ppp pap sent-username XXXXXXXXXXXX password 7 XXXXXXXXXXXXXXXx end

I can not figure out which protrocol the router is using.

How can I know it? As the router as no good performances before working on MTU and mss I would like to understand if it's using PPPOE or PPPOA.

May any of you help me?

This is I am pretty sure PPPoA.

The Dialer is the same in both cases.


pvc 8/35 pppoe-client dial-pool-number 1

R1#sh pppoe sess 1 client session

Uniq ID PPPoE RemMAC Port VT VA State SID LocMAC VA-st N/A 2602 0090.1a71.1b20 ATM0/0 Di1 Vi1 N/A 000f.f7f9.7a70 VC: 8/35 UP

PPPoA bridging: interface ATM0.1 point-to-point bridge-group 1 pvc 0/35 encapsulation aal5snap

N1#sh pppoe sess N1#

PPPoA routing: interface ATM0.1 point-to-point pvc 0/38 encapsulation aal5mux ppp dialer dialer pool-member 1

h#sh pppoe sess h#

These are clearly only particular examples

PPPoE would require some different config lines, and you'd see config lines with pppoe in them.
