Easy question: Getting from Aux to Console port

I am trying to get from the aux port on 1 router to the console port on another router. I have the correct cable running between the 2 devices. I have looked up how to do this on this site and an article says you can but doesnt say how. Any chance someone can help?

Thanks!

Hi,

Can you try the following on the aux port:

Re: Easy question: Getting from Aux to Console port

Try the following:

Router with aux port:

---------------------

line aux 0

transport input telnet

Then issue the 'sh line' command and determine what port number your aux port is.

To connect over the aux port:

telnet <2000 + aux line number>

Typically, if your aux port is 1, you would do:

telnet 10.1.1.1 2001

assuming 10.1.1.1 is an active IP on the router.

Hope that helps - pls rate the post if it does.

Re: Easy question: Getting from Aux to Console port

I have set up the router (which has the Aux port connected) with a loopback address 10.1.1.1 255.0.0.0 and then issued:

ip host (target routers name) 2009 10.1.1.1 (its a 2501 thus the 2009)

I thought this could establish a reverse telnet session out the Aux port but I get a connection refused error.

Does the console need to be configued on the target router?

Re: Easy question: Getting from Aux to Console port

Paresh,

Thanks for your help! This is what I have as far as relevant config.

ip host buildinga 2001 10.1.1.1

interface Loopback1

ip address 10.1.1.1 255.0.0.0

line aux 0

transport preferred telnet

transport input all

transport output pad v120 telnet rlogin udptn

If I issue the command telnet 10.1.1.1 2001 I get

Trying 10.1.1.1, 2001 ...Open

But it just hangs there. I have to clear line 1, on another telnet session, to get it to unhang.

Doing a show line gets me this:

BuildingB#sh line

Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int

0 CTY - - - - - 1 0 0/0 -

1 AUX 9600/9600 - - - - - 13 1 67/1400977 -

* 2 VTY - - - - - 25 0 0/0 -

* 3 VTY - - - - - 3 0 0/0 -

4 VTY - - - - - 0 0 0/0 -

5 VTY - - - - - 0 0 0/0 -

6 VTY - - - - - 0 0 0/0 -

I am concearned about the overrun number.
