how to retrieve config without password

Discussion in 'Cisco' started by Peter van de Meerendonk, Jul 19, 2004.

  1. i 'inherited' a router without the necessary password.
    i think i know the routing table, but i'm not sure.
    i have physical access to the router.

    is there any way to retrieve the configuration ??

  2. Search on for 'password recovery' and the model of the
    router you have. It'll have step-by-step instructions for doing what
    you need to do, including saving the current config if needed.

  3. best thing to do is see what the config register is set to (use show version
    in enable mode)

    for normal boot it should be 2102. if it`s 2142 you will bypass the
    startup-config file.

    If you want to recover the startup without losing the config, power cycle
    the router and when it loads up press CTRL Break together (using
    hyperterminal). At this point there will be one of two choices, either o/r
    0x2142 and then type i and press enter to reload or confreg 2142 then
    reload. Which you would used depends on the router you have.

    when the machine starts up it will ask if you want to run the setup, choose
    no, when you are at the prompt, log on, type enable, copy startup-config
    running-config , conf t, enable password (what ever you want) enable secret
    (what ever you want), ctrl z, copy run start, password reset to your own

    from config mode, enter config-reg 0x2102, ctrl z, then type reload, jobs a
