I'm trying to setup an 1841 with an ADSL 1 WIC and PPPOE but having difficulty.
IOS version is :
Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 15.1(4)M6, RELEASE SOFTWARE (fc2)
I follow the Cisco procedure, but get stuck at the protocol command. I only get options for L2F and L2P, not PPPOE,
Can anyone help?

Hi Leo, thanks, but I think you'll find that's a red herring, the line isn't actually plugged in at the mo.
My problem is it won't accept the commnads to set it up. Specifically, the PPPOE command. I only get options for
L2F and L2P, using Cisco recommended procedure.
1. Since it seems to be a layer 1 issue , can you please try to put the command "dsl operating mode auto" under the physical interface.
Please follow the above procedure:-
dsl operating-mode auto
Shut/no shut ---- do shut/noshut to see the activity od ATM interface
interface ATM0.1 point-to-point -----always create a point-to-point sub interface.
no ip address
encapsulation aal5snap ------Can try to use encap aal5mux and others if telco hasn't specify anyone yet.
pppoe-client dial-pool-number 1
Create dialer interface and bound it with the same as follow:-
ip address negotiated
ip mtu 1492
ip nat outside
dialer pool 1
Ppp authentication pap chap callin
ppp chap host name
Ppp chap password
Run debugs (debug ppp negotiation) and "debug atm events" and share the outputs if problem still observed with the running configuration.
Thankls for that,
Now I get this:
Rosina(config-if)#ip mtu 1492
Rosina(config-if)#ip nat o
Rosina(config-if)#ip nat outside
Rosina(config-if)#dialer pool 1
Rosina(config-if)#ppp authentication pap chap callin
Rosina(config-if)#ppp chap host nanme aliceadsl
% Invalid input detected at '^' marker.
I.e. it doesn't like the username
As per the commands it seems like there is some mistake while putting the hostname , it should be like PPP chap hostname firstname.lastname@example.org and PPP chap password ******
Please try and see if that works.
