Out of band management with modem

Can anyone explain the concept of out of band management using a modem and a Cisco router? I know that the modem would be connected to the aux port of the router and I've looked at the configuration guides on the Cisco site but I can't see any examples of what tools to use to dial-in to the router etc.

For example, can I use hyperterminal and a PC with a modem connection to access the router? How is this done?

    Accepted Solution

    Modem port on Console port - not aux port.
    Use hyperterm to dial into the modem and it is just like you are connected to the console port.
    If you try to use the aux port, the router must be fully up and operational to use it. If you use the console port, the router can be sitting at rommon> prompt and still be able to get to it and recover it remotely.

    Same concept here, except connect to router instead of a switch:
    You can take it a step further and connect the Console port of the Switch to the AUX port of the router, then you can connect to the router and reverse telnet to the switch console. Two for the price of one!
