Cisco 2511 - having probs telnetting to serial port? 2

[rainman]

Hello,

I have a Cisco 2511 terminal server and I'm trying to setup the device to connect to other console ports of other devices in my network (4 cisco console ports).

When I try to telnet to the loopback address and port #, I get "Connection refused", yet if I plug my PC right into that specific console port I know its working at 8,N,1,9600.

Here is the config I'm using on the terminal server ... someone tell me if i'm doing something wrong:

ip host rtr01 2001 172.21.1.1
ip host rtr02 2002 172.21.1.1
ip host switch01 2003 172.21.1.1
ip host switch02 2004 172.21.1.1

int Loopback1
ip address 172.21.1.1 255.0.0.0

Now, i should be able to telnet to 172.21.1.1 2001 to get async port 01, yet I get:

%Connection refused by remote host

This is my first shot at configuring this terminal server doing reverse telnet. I'd honestly like to set it up so I can map specific IP's other than only 1 address to an specific console port (i.e., 192.168.100.1 = async port 1, 192.168.100.2 = async port 2 and so on, so I can telnet to the IP of the async port i want).

If anybody can spot a problem with my current config let me know as I am trying to determine if this access server is bad.

couple things.

regarding telneting to a specific port you can do that

you just have to specify the port at the end of the telnet session for instance

telnet 172.21.1.1 2001 would take you to async1

regarding the connection refused message i get this all the time. check the settings on the console port and aux line ports to make sure that they are all the same. same thing on the terminal lines.

use the command

clear line 1
clear line 2
clear line 3

etc to clear the line that you want to clear and try to telnet again to it.

have fun

No I still can't get my 2511 to let me telnet to the specific async line. I did the "clear line X" command. What options do I need to setup on the console port of the network device I am trying to console to, along with what do I need to configure on the line itself on the term server? Also, I am using the 8-port octet cable that came with the 2511 going right into the remote console ports ... do I need some type of gender changer due to DCE/DTE issues? Even tried another cable (my 2511 came with 2 sets of the cables) and no go.

on the terminal server do this


line 1 16
no exec
modem inout
transport input all
stopbits 1

on the router i have left the console settings blank and it works

Woo hoo! Worked like a charm. Thanks so much I had all of that except the stopbits 1, and I kept asking myself why when i do a show line was I seeing 2 stop bits versus the 1 expected. Knew something was amiss.
