2511 Access Server Problem...Fixed

skelt11

Hi,

I just got all my lab gear but setting up the 2511 is killing me for some reason. I've never set one up before. I've googled it to death and I still can't figure it out. Whenever I try to connect to device I get:

Trying R1 (172.16.1.10, 2001)...
% Connection refused by remote host

Here is my config, what am I doing wrong?

ip host R2 2002 192.168.1.10

Try transport input telnet

Here's my line config

line 1 16
 no exec
 exec-timeout 0 0
 transport input all
 flowcontrol hardware

What IOS version are you running?

I tried adding transport input telnet, the option isn't there. I'm running 12.2 access server

Here is what I get when I typen transport ?

AccessServer(config-line)#transport ?
output Define which protocols to use for outgoing connections
preferred Specify the preferred protocol to use

You can use this as an example - from http://www.cisconet.com/index.php/Cisco/Cisco-Access-Server-setup-for-the-LABCCIE.html

Basically, you should assign the same IP to all of your "ip host" statements - that matches the loopback0 ip address such as shown below 1.1.1.1. You need the line 1 x command, as well as the transport input telnet under the line console.

Try to also issue a clear line tty <line #>

I did see that site when I was looking around for some help. I can add transport input. This is the first device that I've seen that won't let you add it, pretty interesting. I'm running 12.2 and will upgrade to 12.3 when I get the flash upgrade that the company was supposed to have installed for me.

Is there something on the remote device that I need to configure?

I JUST NOTICED THAT THERE IS A YELLOW LIGHT TO THE BOTTOM LEFT OF THE ASYC PORTS ON THE BACK OF THE 2511. THE LIGHT COMES ON BRIEFLY WHEN I PLUG THE CABLE IN BUT GOES OUT. IT SEEMS LIKE THERE IS A LOOSE CONNECTION OR SOMETHING. DO YOUR LIGHTS STAY ON ALL THE TIME WHEN THE CABLE IS ATTACHED??

Nope. Nothing when it's just sitting there. Flickers Green when it's transferring data.

Good Suggestion.

Do you have any problem logging into the console port from a PC to R1 with a Cisco Console Cable?

What's your console port configuration on the remote device? It shouldn't require anything special.

So I tried clearing all the lines over and over and over. Still nothing. I was doing some show commands and this is what I found...no transport inputs allowed. I think that could be a problem. But I do not have a transport input option under either line con 0 or line 0 16. ??????

So I thought it was fixed, its NOT. Now I have another problem. I can now connect to all my devices, check. But when I do, there is nothing on the prompt. I can't type anything, nothing is displayed. If I connect to a device, say R7, and I reboot it I can see the boot sequence. It gets to a certain point and stops. I checked the line speed on both sides via console and they are all set to 9600 baud. Is that wrong? What the h*** am I missing here?

This thing is getting on my last nerve!!! Does anyone have any advice? I

The only thing can think that may be causing it to freeze is that their could be an octal connection mismatch. For example the connection to the access-server may be on the port 9-16 and on the connection to the remote device may be the 1 cable.

Have you tried connecting the line that you cannot access to a different cisco device console port? This would help pinpoint the issue to a device or the access server.

Also have you attempted to use a different ios image?

nicklauscombs

not sure if this will help but you should put "no exec" under line 1 16

Dear,

How much you set the exec-timeout in the conf?

skelt11

Sorry for not replying sooner. I got the 2511 working. And I hate to say what it was....layer 1.

The cables that came with the router have weird tips on them. They have a small piece that protudes a little over an 1/8 of an inch I would say. It wasn't allowing the cables to seat all the way in the console ports. I took some wire cutters and trimmed those little guys off and bam. Now they don't seat that well still and every so often I have to reach over and push them back in a little but they work.

I feel like an idiot for not checking the physical layer better first....
