2511 as a console router help

digilink

I'm not sure if I have something misconfig'd or if this router is just toast, but I'm trying to use a 2511 as a console server and not having any luck.

Here's the config:

sunvalleyar-2511-1#sh run
Building configuration...


Current configuration:
!
version 11.3
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
!
hostname sunvalleyar-2511-1
!
!
ip subnet-zero
ip host 2600-1 2001 192.168.1.1

!
end

I have cable 1 of the octal cable connected to the console port of a 2950 switch. The port itself on the switch is working, I'm able to console to it from my laptop just fine.

I'm consoled in to the 2511 (no network access yet, need to get an AUI transceiver. Speaking of which, if anyone has a cheap source besides ebay please let me know) and if I telnet to 192.168.1.1 2001 it just hangs, no prompt nothing. I end up having to power cycle the router just to get back to the prompt.

Is there anything in my config that could be potentially screwed up that would prohibit this from working as expected? My first thought was that I need to set the baud rate for line1 but wasn't sure what the default was on these (I assume it's 9600-8-N-1?)

Thanks for any insight....

EDIT: This is an example of what happens when I attempt to telnet to the address/port:

sunvalleyar-2511-1#telnet 192.168.1.1 2001
Trying 192.168.1.1, 2001 ... Open

Where do you config the port numbers for the octal cable connections on 2511? (sorry I use digi CM32).

Should the Async1 interface be shutdown like it shows in your config and not be configured?

To the best of my knowledge (and believe me, it's small at that currently!) the port numbers are config'd with 2000+1 (2001, 2002, 2003, etc) and they correlate to line's 1, 2, 3 etc.

As for the Async, that's a good question, I honestly do not know and all the examples I have been able to find do not indicate that it has to be config'd but not sure.

Try doing a SHOW USER and then a CLEAR LINE # of the indicated line. Try the CLEAR LINE several times if it doesn't clear the first time. It's been a long time since I used my console server, but I remember that being a recurring problem.
You may also want to try using TRANSPORT INPUT ALL on lines 1 - 16.

You have to specify what is what... Here is my config off of my 2511 at home

Works just fine

If you are consoled in I don't think you will be able to do a reverse telnet.

What happens when you type 2600-1

When you get the open prompt you need to hit enter a couple times ??

Are you sure you have cable 1?

If you do a show line you will see what lines are active,

I will get my config when I fire up my rack next.

had a similar problem with my 2509
spent a whole morning trying to troubleshoot this mysterious hanging line.

turned out that i had to power up the remote devices FIRST and then start the terminal server.
don`t ask me why or if this thing is reproducible on every 25XX router, just a thing you might try if config and cabling are correct.

Thanks for all the replies so far.... I appreciate it. I think this router may just end up being bad, at least as far as the Async ports go.

There's a little bit of history with this device, about 4-5 years ago our building that I got this from got hit by lightning and it never worked right since. It was laying around at the office so I figured I'd give it a shot again to see if maybe it was misconfig'd or what not.

I just tried another port (port 2) and I'm getting the same results. I also noticed the baud rate was set to 19200, so I set txspeed and rxspeed both to 9600. Still no joy... this sucks! I got this for free hoping I could use it for an access router. These go for around $250.00 on Ebay... ouch!

I think the serial and AUI ports are still good on this router... so maybe I can at least use it for that.

Here's the latest config, in case I missed something. I do see the activity light on the Async port "blip" when I hit enter for example, so I think it's connected but don't know:

Everything look correct?

Dumb q... Have you tried to telnet 2001, also make sure your cabling number is correct, 1 is the upper left hand most cable on your Octal

sexion8

Change your transport input from telnet to all as well

 transport preferred telnet
 transport input all
