[b]2511[/b] terminal server setup help

Darken Rahl

I need help setting up my 2511 reverse telnet to my other 5 2500 routers.
I have added an ip address to a loopback interface and also added 2000+port in the ip host table.
What in terms of config is required on the connecting routers?
Any help would be great.

Thanks.

I am asuming that you have the Octal cable on and the other cables running to the console ports..correct?

If you want to connect to the first router......we will call it R1...
on the terminal server you should have the command:

Router(config)#interface loopback0
Router(config-if)#ip address 1.1.1.1 255.255.255.255
(that is just an example of the first part)

Now for the ip host commands:

Router(config)#ip host R1 2001 1.1.1.1

You will also want to run the command: Transport input all ....at a minimum, use transport input telnet. Once you get connected, you might want to do some tweaking on the lines....but that is up to you..


Once this is saved...all you will have to do is type R1 and it takes you to the router's console port.

does that help?

I have now setup both ends as per the instructions given by Ten9t6.
i now have the following message returned when trying to connect;

% Connection refused by remote host
I am using an octal cable with the Async port enabled and terminating in the console port of R1.
Both routers have the same enable secret password and vty passwords.

Any ideas?

hmmm....

if you plug a console cable straight into the console....and bypass the terminal server...can you get into the router?


Also on the terminal server....do a clear line 1 and then 2 and so on....then try the connection again.

Let me know if that doesn't work....

i have tried everything you have suggested and all I can think of and source from cisco help docs, but the connection can not be made via the octal cable.
The routers can all be accessed and via the console port as expected, I have tried 3 different routers via the terminal server octal cable and get the afore mentioned error message.
Please can someone send me a complete guide to setting this up with upto 8 routers, showing all commands and configurations required at both ends of the connection.
I presumed the Async ports would need to be enabled for this reverse telnet link is this right?
Also will the Async ports require ip addresses or is this just required on a loopback address?
I am starting to confuse myself and loose all sense of logic?
Any help would be fantastic.
Thanks.

All is working ok now, it seems I made a configuration error, which I overlooked when double checking the setup.
I had used the 'transport input all' command on the vty lines instead of the tty lines.
Sorry for the stupidity.
Thanks for all the help dudes.
