Hello Experts,
I have newly purchased Cisco 887 Router. I am trying to replace this router with the exisiting ISP provided modem I am facing an issue to bring the ATM0 port up.

My ISP modem is just accepting the ISP's username and password and giving the auto setting like IP,PVC info etc

Here is my router config

Please help to resolve this issue.

Hi,
you probably need to set ppp over ATM and not ppp over Ethernet:

you should try the following (please be sure that pvc numbers are exact, your ISP should tell you):

interface ATM0
no ip address
no atm ilmi-keepalive
pvc 0/35
encapsulation aal5mux ppp dialer
dialer pool-member 1

interface Dialer1
ip address negotiated
ip nat outside
encapsulation ppp
dialer pool 1
ppp authentication pap chap callin
ppp chap hostname XXXXXXXXXXXXXXXX
ppp chap password 0 3920
ppp pap sent-username XXXXXXXXXXXXXXXXXX password 0 3920

that's all you should need, (i can't see what reference has the "ip access-group 101 out" in your config)

hope this helps

Hi,

On my modem, after providing the username and password ( given by ISP) the release auto configuratio It shows pvc value as 0.200
i forgot to remove that access group.

Hi,
i've never seen pvc 0/200, i believe you're using the wrong number.
You should check with your isp (they MUST tell you).
You may want to try pvc 8/35

Hi,
By the way my Cisco Router 887 is not supporting this command

dsl operating mode ansi.

Thank

max_the_king

its under ATM configuration:

dsl operating-mode ansi

on 877 is supported, try

dsl operating-mode ?

and see the options

its independent from pvc
