I have a 2901 with an HWIC 16A module to be used as a terminal server, I am using the green Cisco 8-port async cabl The menu is working and I can see the line go active when I try to launch a console session, but the session just hangs as if there is no connection to the remote device, which is a cisco 3560X switch: Anyone see anything glaring? Building configuration... Current configuration : 5696 bytes
! line con 0 exec-timeout 0 0 password password login local no exec transport output all |

OK. The first thing you need to do is to remove the command no exec from the console of the switch. That for sure causes problems.
Also in a terminal server there is usually a host definition that ties a host name to an address and port. I see in your description something that looks like it is there (Trying ASA_1 (1.1.1.1, 2003)) but I am not seeing anything like that in the config that you posted.
If that fixes the issue then great we are done. If that does not fix the problem then there is something else we have to find. I have not used this model router with this type of interface as a terminal server so I have no real experience in this particular environment and am guessing at the issue. But I worry about the encapsulation slip configured under all of the async lines. When I have configured terminal servers that work I have not had encapsulation slip on those interfaces.
If that does not get it to work then I wonder about the relationship of line numbers to port numbers. Would you post the output of show line from the router?

The host lines are there, I think I just cut them off :
ip host ASA_1 2003 1.1.1.1
ip host ASA_2 2004 1.1.1.1
ip host 4500_1 2005 1.1.1.1
ip host 4500_2 2006 1.1.1.1
Here is the "sh line" I am using the 16 port HWIC and the green octal cables. I have the cable plugged into the HWIC 0

Thanks for the additional information. You asked if we see anything glaring and the absence of port assignments to host names was pretty glaring. I am glad to know that they are really in the config and just did not make it into what you posted.
And the correlation of line number and port number looks right.
So what about the other issues/possible issues that I mentioned? Have you removed the no exec from the switch console? Have you tried removing the encapsulation slip from one of the lines that you are testing?

I can see that line 3 is the one attempting to make the connection.
I am assuming that slot 0 in the HWIC and P0 is the correct cable to be using for this connection.
I did try each one of the eight cables earlier though and still couldn't get a connection.

It is either on or the other, if you remove one, it flips to the other encapsulation type.
01-14-2015 02:00 PM
I am surprised that it requires one or the other of slip or ppp. I wonder what would happen if you did this in global config mode
default interface Async0/0/0

Thanks for the help Rick,
The problem turned out to be the cable.
Also, the interfaces are configured for SLIP encapsulation and are working.

I am glad to know that you have solved the problem and that it turned out to be the cable. Thanks for letting us know that the interfaces are configured with slip and are working. I am slightly surprised and glad to have confirmation of this.

I noticed the encapsulation SLIP also, but wasn't sure if that was an issue or not.
I just changed the encapsulation to PPP with the same results and the "no exec" has been removed from the console port of the device I am attempting to connect to.
Still no luck.

Thanks for the additional information. Sorry it still is not working. What about removing the encapsulation ppp and not specifying any encapsulation on the async interfaces?
