2511 configuration

See if the sessions are already connected and/or try clearing the line. I stumbled over that.

What port are you trying to connect to?

Do what dynamik said as well.

Is there any need to do any kind of console port configuration on the device the octal cable is plugged into (not the 2511 router)?

I have used cisco's configuration verbatim from cisco's website. I can use a console cable and connect to my devices, but the access server config on a 2511 will not work. I keep getting connection refused.

any suggestions????

liven,

Do you have a link to the "...cisco's configuration verbatim from cisco's website...?"

I'm assuming it's this one.

The link:

http://www.cisco.com/en/US/tech/tk801/tk36/technologies_configuration_example09186a008014f8e7.shtml

is exactly what I am using.

So you saying that the connection automatically establishes itself? I am not trying to be argumentative, just not following.

I finish the config in the cisco doc that we have linked. And then I try to telnet to the device and I get connection refused.

Do "show line" and see if any have a * at the start. If so then that line is busy. Use "clear line <number>" to reset it. Try connecting again.

liven,

Exactly including the use of the IP addresses of 171.55.31.5 and 171.55.31.1?

Don't really follow you here, but that is ok. I will try a

show line

and see if they are already connected

You said "...is exactly what I am using..." where that link has a router configuration using the IP addresses of 171.55.31.5 and 171.55.31.1. So I ask again, did you use the configuration listed on that webpage exactly including the use of the IP addresses of 171.55.31.5 and 171.55.31.1?

No I am using different addresses.

I don't see the address 171.55.31.1 on cicso example.

I am using 172.16.10.1 as my loop back address, and then adding sequential port numbers to 2000 for each ip host.

I am currently consoled directly into the 2511 router. So I do not need a default gateway or anything like that.

It looks like those are for the ethernet interface and default route. Those aren't going to affect what you're trying to do.

Did you notice this part: !--- Configure lines 1 - 16 with at least transport input Telnet.

Did the show line give you anything?

This is exactly what the problem is, but there was no command to enable the transport input telent. HOWEVER, by using:

conf t
line con 0
exec-timeout 0 0

I achieved the same affect.

Now I can telnet to my loop back on the port number I have assigned to the device the octal cable is acconcted to and BINGO. Life is good.

Thanks to Tech-airman and my brother Dynamik for the help!

Here are the IP addresses of 172.55.31.1 and 171.55.31.5...

To use an access server, you're supposed to connect to the router through the Ethernet port and NOT the Console port. So for example, by using a Windows Command prompt you type ">telnet [IP address of Ethernet port of 2511 router] [port number]" where the port number corresponds to which octal cable that is connected to the Console Port of the networking device you wish to manage by access server. So actually, you DO need a default gateway "...or anything like that." to help route the access server traffic back to your computer's Ethernet port and NOT to the computer's Serial port. Does this make sense?

He has a console connection to the 2511 and he is telnetting from there to the other routers. That's how I have mine setup as well.

dynamik,

Does that mean in order to see the router outputs he's going to have to use keyboard gymnastics to flip around to be able to see the various router outputs from a single terminal window?

Are you trying to give me a hard time or are you genuinely asking how this works?

It's just like I said. All you do is telnet to the other devices once you're consoled in to the 2511. When you set up your hostnames, it's really slick. I just type "r1" to go to my first router. Ctrl-Alt-6 + x to suspend the session and go back to the 2511. Then "r2" or whatever to the next device, etc.
