Cisco 801 Problem

Discussion in 'Cisco' started by Matthias Tinnemeier, Dec 9, 2003.

  1. Hi there!

    I bought a used Cisco 801 last week. Because i never worked on a cisco
    router before, i decided to use the SmartStart software to configure the

    My setup is a small office-lan within some windows clients, a sni
    primergy 460 linux box as dhcp-/fileserver. the cisco router should do a
    dial-on-demand internet connection (dynamic IP) over isdn to T-Online
    whenever a client want to connect to the internet.

    The 801 has the ip, clients get this ip as default gw and
    the t-online nameserver over dhcp.

    i've choosen the preconfigured "German T-Online" profile in the
    SmartStart Software but it didn't worked. So i the router won't dial in
    when i ping an internet-adress or an internet-ip from a client.

    Then i used the Cisco ConfigMaker to configure the router with the same
    result. My Config-File is attached to this posting.

    I don't understand why this won't work. Please help!

    ...sorry for my bad english...

    You are likely having isdn issues. You need to determine which switch type
    your telco is using or emulating. Then configure this under int bri0 with
    an "isdn switch-type" command. You also may need to know your spids
    depending on the switch type. They will be configured in the same place
    with isdn spid1 ####### and isdn spid2 #######. You can view the isdn
    status with a "show isdn status". There should be two lines that say spidx
    sent, spidx valid.

    To determine isdn layer two issues, telnet to the router. Go to enable mode
    and type "term mon" (this will redirect the output to your telnet session).
    Then type debug isdn q921. The output may be a little cryptic, but you
    should see roughly the same amount of traffic both directions. If the
    problem appears to be layer 3 isdn (telco infrastructure and digit routing),
    you can use debug isdn q931 (however, you should turn off all debugging
    first "undebug all" or "no debug all")

  3. Yep, that may well be it. He's in Germany, so no SPIDs, but his
    switchtype is set to 'basic-1tr6'. Even in Germany, that's not often
    used any more.

    He should try 'isdn switch-type basic-net3'.

    The rest (if it still doesn't work after the change) is good advice.

  4. Thanks! basic-net3 was the key... it works!

    became obsolete, use

    isdn switch-type basic-net3

    do you need a working example for MSN in germany?
