cisco 887 adsl "Interface Vi1 unbound from profile Di0"

Hi everyone

i recently got an 887 adsl router to be added for internet.... hoping the configuration should be the same as 877 i have done the following configs...

interface ATM0

no ip address

no atm ilmi-keepalive

!

interface ATM0.1 point-to-point

pvc 8/35

  pppoe-client dial-pool-number 1

interface Dialer0

ip address negotiated

encapsulation ppp

dialer pool 1

ppp authentication chap pap callin

ppp chap hostname ******

ppp chap password 0 ***

ppp pap sent-username ****** password 0 ***

with this config on a 877 it works perfectly... but on the 887 it doesnt... the basic output i get is as follows

*Jul 11 21:22:31.111: %DIALER-6-BIND: Interface Vi1 bound to profile Di0

*Jul 11 21:22:31.115: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to up

*Jul 11 21:22:31.119: Vi1 PPP: No remote authentication for call-out

*Jul 11 21:22:34.307: %DIALER-6-UNBIND: Interface Vi1 unbound from profile Di0

*Jul 11 21:22:34.311: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to down

Am i missing something on the 887?

Afshan,

So far, we have tried everything reasonable. We streamlined the configuration and removed unnecessary commands, we have verified its correctness, we have even reviewed the debugs closely. We have gone as far as stripping every functionality from the Dialer interface and leaving it to build a basic plain PPP connection with practically no Layer3 protocol being transported or even allowed on it. Everything was unsuccessful. At this point, I am willing to say that this looks like an IOS bug.

Do you have an option of trying a more recent IOS version for your router, i.e. 15.1(4)M, or perhaps downgrading back to 12.4(24)T5?

Also, do you have a support contract with Cisco? If so then you can raise a TAC ticket directly from this thread. I guess Cisco TAC engineers would have a pretty good overview of what is going on basing on the wealth of debug information and experiments we've done in our conversations here.

Best regards,

Peter

Hello Afshan,

Unless you are absolutely sure you need the command ppp authentication chap pap callin then please remove that command from your Di0 interface. If that does not help please run the debug ppp negotiation and debug ppp authentication and enclose the results in your response.

Thank you!

Best regards,

Peter

Peter

yes i am not sure about the "callin".... and therefore i did try removing it.... and using "ppp authentication pap chap"

this is the responce form "debug ppp negotiontion"

Afshan,

Please remove also the command ppp authentication pap chap - in other words, there shall be no command present in the Dialer0 configuration that starts with the words "ppp authentication". Using that command, you are forcing your DSL provider to authenticate to you which is wrong - only you are authenticating towards your DSL provider, not vice versa. Your Di0 configuration should look only as follows:

interface Dialer0

ip address negotiated

encapsulation ppp

dialer pool 1

ppp chap hostname ******

ppp chap password 0 ***

ppp pap sent-username ****** password 0 ***

Give it a try - and if it does not work either then please enclose the output of the same debug commands once more.

Best regards,

Peter
