2511 configuration

hey guys,

I'm finally getting around to my 2511 now that I have a transceiver for the AUI port.

I tried checking out websites that show you how to configure the octal cables and I seem to be missing something pretty important. I am getting this error when trying to connect to one of my routers.

Router#rtr-1811
Trying rtr-1811 (192.168.168.1, 2001)...
% Connection refused by remote host

here's my config.

!
!
no aaa new-model
ip subnet-zero
no ip domain lookup
ip host rtr-1811 2001 192.168.168.1
!
! 
!

end

Thoughts? this is the 2511 with the octal cables, not the RJ-45 one...

I'm currently consoled into the 2511.

Do "show line" and then "clear line".

Here's my "show line".

When I try clear line, it says invalid command. I have to put in a line number like: clear line 1

It said "OK" but it didn't seem to make any difference...

thenjduke

type in 1 instead of the Router Name after first time of connecting. I had same problem. You can show line and clear line as tiersten explain. Remember the name is associated with the line like 2001.

thenjduke

One other thing on the Router or Switch connecting too did you type under line console 0 login and set no password? I did this and was not able to get in through console port. I had to reset the entire switch.

To make sure I jumped on my router and went to the console line and typed this:

no login
no password

When I issue show run, it doesn't seem to show these two commands though, but when I directly console to the router, I get right in, it doesn't ask for password. I think it has AAA new-model enabled though, that shouldn't be problem though right?

line con 0
 exec-timeout 0 0
 privilege level 15
 logging synchronous

I'm going to turn on another device and try to connect, let's see if it's the 2511 or the 1811 router...

I also tried typing just "1" and even "2001", it didn't do anything...

I tried cable #8 plugged into my switch. Same results below:
And you can see the different commands I tried.

Now I'm starting to get concerned.....

I don't understand, how can the connection be refused?

Both devices don't have login/password on their consoles.

When I plug directly to their console ports, I get right in....

I had the same problem as well.

What does sh sessions list?

I would also save the config and reload the router.

I'll go ahead and reload the router. Here's my SHOW SESSIONS as well as my SHOW VERSION just for FYI....

I got it working. Here's what I was missing...

Router(config-line)#transport input telnet
Router(config-line)#exit

Yeah, I just found this command online, didn't know it existed since it's my first access server! But I'm relieved now that it works!

whew!!

thenjduke

notgoing2fail I went through the same thing with you. Took me almost 3 hrs to get it up but I learned from scratch. I forgot about that command. I just got one last week. Let me tell you it frigging helps out so much to have this. I actually have IP address associated with mine and I just telnet into that now

Sorry forgot about that command.

notgoing2fail,

Another thing to look out for (or maybe its just mine)... but I sometimes have to clear the same line more than once. To prevent the connection from being refused... This doesn't happen too often, but it typically happens when I telnet to the router from one PC and then console to the router from my other PC... just a little FYI. I hope this helps.

Glad we're on the same page. I thought I might have gotten either bad octal cables or just a bad 2511. This can cause a lot of grief for new 2511 owners. Many links I checked out before asking for help were of no help until I got lucky on that last command....

This is going down in my book of tips....

I've been getting them because I've been moving things around. I completely forgot about clearing the lines. So I've been reloading the router.

You live and learn....many of these commands won't ever transfer to other routers so it's hard to remember...
