access server 2511 to emulate hyperterminal

[fabiangp]

I do not want to use telnet from my access servers to the consoles. I want to do exactly what hyperterminal does. Can it be done? That way when I plug a new router to my access server I can access it right away instead of having to configure transport in the destination router console. Does anyone know how to do that? This is my current configuration for tty line 6. Now I need to know how to connect to that line.

line 6
session-timeout 20
no flush-at-activation
absolute-timeout 60
transport preferred telnet
transport input all
transport output all
stopbits 1
flowcontrol hardware

I tried udptn and rlogin but those connection type do not work. Thanks.

Set up reverse telnet in the access server. You will need an octal cable, the serial end plugged into the access server and the RJ-45 ends each plugged into a router console port.

ip host R1 2001 192.168.1.1
ip host R2 2002 192.168.1.1
ip host R3 2003 192.168.1.1

etc...

int lo0
ip add 192.168.1.1 255.255.255.255

Then, from the access server

router#R1

It then connects you.

fabiangp,

What Burt posted - that is how the "online" Cisco labs rent time and you are able to blow away the config and start from scratch !!!

I have set it up on a 2511-RJ and a 2509 with an octal cable and it works pretty good! I have also used it in online Cisco labs and it worked great - they were using 2600's with the Network Module to do the same as the 2511's.

I did that and did not work at all, I have the same configuration 2511 octal cable connected to 3550 console, I can hyperterminal to the 3550 but no luck from the access server. Any ideas?

Thanks a lot for your help. I finally decided to use a different wire and it is working perfectly. In the future I will pay more attention to the noise indicator.
