I have just purchased 2901 with HWIC-16A and 2 CAB-HD8-ASYNC Terminal Server to manage 16 (connect via console) cisco deivces.
Plese find attached the config file. I could not find proper docs on setting up this device as a terminal server. I have followed the following link but did not work.
http://www.cisco.com/en/US/tech/tk801/tk36/technologies_configuration_example09186a008014f8e7.shtml
There are 16 Async (0/0/0 - 15) interfaces and also the following lines.
line 2
line 0/0/0 0/0/1
line 0/0/2 0/0/15
How can I connect to other Cisco devices via the terminal router?
Can anyone explain me the usage of above 16 Async interfaces and lines.
Thank You
Solved! Go to Solution.
Cisco uses the convention 2000 plus the line number. So if your device SW01 you wish to connect with is on physical port 0/0/4 = line 7, then you should be able to telent using your async server IP on port 2007,
The link works fine for me. (You need to be signed into cisco.com as a registered user to use that link.)
Your basic configuration looks fine.
To connect to the devices, map out a cheat sheet with lines to ports. Each physical line will have a separate tcp port starting at 2001 for async port #1 etc. (I believe "show lines" will list them for you.) You can then log into the terminal server and specify the tcp port for your telnet or ssh session to be redirected to the attached device's console.
The shortcut suggested in the link above is to use commands like:
ip host 3600-3 2014 172.21.1.1
!--- The host 3600-3 is connected to port 14 of the comm server.
!--- Ensure that the IP address is that of an interface on the comm server.
Your cables shoud all go to the downstream devices' console ports.
Following is the output of show line command and I have connected the cable P4 from the terminal router to a spare switch console. Also configured the following command on the console router
ip host SW01 2007 10.10.10.6
Now I can not telnet to 10.10.10.6 2007
How can I find out what port correspond to which port?

Line(s) not in async mode -or- with no hardware support:
19-387
Cisco uses the convention 2000 plus the line number. So if your device SW01 you wish to connect with is on physical port 0/0/4 = line 7, then you should be able to telent using your async server IP on port 2007,
The following command was missing,
line 0/0/0 0/0/1
transport input all
transport output all
Now it works fine.
Thanks for this post helped me troubleshoot.
This post helped me out, but why does it have to be transport input/output all? I tried going through each one individually and neither of them worked alone. I was trying to figure out a way to lock it down more.
