Cisco Router 887 int atm0 issue

[noumanwww]

we have cisco router 887

we have ADSL service. We enable the Controller VDSL0

but the Interface ATM0 is not getting UP.

we want to disable the controller vdsl0 but we can not disable it.

we reset the router to factory default still the same issue.

is there any solution for it.

Controller VDSL should not be disabled.  Leave it as is.

You don't say which country you are in or which ISP you use, so it is very hard to make suggestions, but you will need a config like this:

interface ATM0
dsl operating-mode auto
pvc 0/100
 encapsulation aal5mux ppp dialer
 dialer pool-member 1

Do you know if you need PPPoA or PPPoE (or something else even)?  Do you know what vci/vpi numbers you are meant to be using?

If you are still see the ADSL line down then I would be most suspicious about the ADSL line.  How do you know the ADSL line is working?  Can you test it on something else?

pvc 0/35

i apply all the above setting

DSL line is working fine on another router. i need pppoe config

int atm0 light is coming but not stable

[Philip D'Ath]

Something like this:

interface ATM0
 no ip address
 no atm ilmi-keepalive
 pvc 0/35
  encapsulation aal5snap
  pppoe-client dial-pool-number 1

interface Dialer0
 ip address negotiated
 no ip redirects
 no ip unreachables
 ip mtu 1492
 ip nat outside
 ip virtual-reassembly in
 encapsulation ppp
 dialer pool 1
 dialer-group 1
 ppp eap refuse
 ppp chap refuse
 ppp ms-chap refuse
 ppp ms-chap-v2 refuse
 ppp pap sent-username <username> password <password>
 ppp ipcp dns request
 ppp ipcp route default
 no cdp enable

dialer-list 1 protocol ip permit

ip route 0.0.0.0 0.0.0.0 Dialer0 permanent

[noumanwww]

i tried the above  configuration

still int atm0 is blinking not stable

i am not sude about the encapsulation?

1) encapsulation aal5mux ppp dialer

2) encapsulation aal5snap

[Philip D'Ath]

You need to use the same encapsulation as your service provider.  Who is your service provider and I'll try and find out, otherwise try asking them.

You should be able to verify the state of the DSL link using "show controller vdsl 0" or possibly "show dsl interface atm0". The exact command depends on the hardware and IOS version.
