Connect Catalyst 2900XL console port to router aux port?

[rainman]

Can anyone explain to me how I would go about connecting a Cisco Catalyst 2900XL to allow me to connect to my router via the switch's console port to the router's aux port?

It's tough to justify modems and phone lines hanging off all our routers, so I'm trying to see if we can just get to the switch, then go out of it's console port, IN to the router's aux port.


Any thoughts?


Thank you,

Rich

I'm a little confused about what you are trying to accomplish. It sounds like you are trying to access the router's configuration. If so, why don't you just telnet to its IP address?

You can only do that the other way around, like go from the AUX port on the router to the console on the switch..

go to your AUX port on the router and do this

line aux 0
modem InOut
no exec
transport input all
stopbits 1
speed 9600


then you'll have to find out what your line number is of the aux port and do a command like this &quot;telnet <router address> 20xx&quot; and the xx meaning what the port number of the aux is.. This is called reverse telnetting.

hope this helps

There is a whole entire FAQ on it here: It is called Reverse Telnet:
