You are using the first TTY line for your reverse telnet. My first guess is some kind of connectivity problem. Can you confirm that you are connecting that first line to the device to which you want to console? Can you specify what kind of cable connection you are using? Can you confirm that the device to which you want to console will accept a direct connection on the console port?

thanks for the input, here is some more info that may help
I have a octal cable line 1 going to sw1 , 2 going to sw2. 3 going to R1 and 4 going to R2..on the server I did config a the loopback0 with 192.168.10.10....then I did configure the
# ip host sw1 192.168.10.10 2001
# ip host sw2 192.168.10.10 2002
# ip host r1 192.168.10.10 2003

Hi, ocporbust
There are two async ports on 2511 router.The lower port is labeled ASYNC 1-8, and the upper port is labeled ASYNC 9-16. Could it be that you are connecting to the upper port which is line 9-16?

Hi Karim,
The configuration is fine, do you face problems when trying to connect to all the devices or just this switch.

I am not able to access all of them .. all I get is open message and its stays there.. I am going to see if I can connnect directly to each device

Karim,
If you can access them directly then it is most probably a cabling issue.
