  • Cisco 857 config help


    I have a Cisco 857 ADSL router which i am currently trying to setup for my UK internet provider BeThere (which is similar to O2). We currently use a Speedtouch router and would like to move over to the Cisco.

    This current config allocates IP addresses to computers plugged in to the ethernet ports, but i cannot get any internet connection. I can login to the router using a serial terminal connection, and connect through the SDM gui.

    When connected to the phone line none of the ADSL lights light up at all (CD/RXD/TXD).

    I have a single static IP address (which i have replaced as in the config example)
    Bethere uses:
    RFC1483 Routing with AAL5SNAP encapsulation

    Here is the info of the router:
    Cisco IOS Software - (C850-ADVSECURITYK9-M), Version 12.4(15)T7
    ROM: System Bootstrap Version 12.3(8r)YI4,
    System image file is "flash:c850-advsecurityk9-mz.124-15.T7.bin"

    Any help getting this up and running would be great.

    Here is the current config:

    service timestamps log datetime msec

    could you post output of show dsl please ?\

    I also suspect, for ADSL, you may need a dialer0 interface... ?

      Cisco857#show dsl
      % Incomplete command.
      so i tried this...

      Cisco857#show dsl interface

      Training log enabled, but not collected yet. Because
      there have been no state transitions since log was enabled.
      You can force a state transition through shut/no shut.
      If shut/no shut is already done, please wait for few seconds
      for the transition to take place and retry "show dsl"
      I think you may be right about needing a dialer, i copied most of the this from another config (search google for cisco 877 bethere static and its the first result) which does not have a dialer section so i may be missing something important!.

      What is the best way to create a dialer interface?

        looks like your line isn't activated.
        Do you have another device you can try ?

          Yes, our broadband works fine with our speedtouch router. The cisco is second hand, so i am not sure if it actually works. Would the ADSL lights usually show some signs of life regardless of the config?

            yes - cd should be light up, or at least flashing madly while it tries to train up

            maybe if you can't get the adsl to work, you could put the speedtouch into bridge mode, and use it just as a modem on the cisco router?

            try also,
            conf t
            int dsl
            no shut

            i'm not sure if that'll work though
