2511 Access Server - problems

it says open which means the access server is working try trouble shooting the other end console port. Try to connect with out the access server and see if it works HTH

have you hit enter after the "open" message?

I removed all the octal cables
I hit enter after it says open, but it never goes past that step.
I consoled in on one of the routers could get to a prompt and login, but it will not do the same with the 2511....ayone have any ideas?

Is this your first time configuring it or has it worked before and it just started acting weird?

And then you plugged at least one back in the correct connector and confirmed that you had the correct # cable plugged into the console port of the router you just tested?

This is a brand new config. I have never gotten this to work. My octal cables are labled 0-7, so itake it 0 would be line 1 2001. I have tried all the cables and have two sets of them, and none of them get past that point. Is there anyhting in my config i don't need? Or is there a better config to use. I can console in to the routers or switches, but can't access server in.

Depending on which connector the octal cable is conneted to will dettermine if it is line 1-8 or 9-16. If you are usnig the one marked 0 then it is either line 1 or 9. Also there are different types of octal cables available, do you know which one you have (part number)?

I understand which set of cables ar 1-8 and 9-16, not sure, can 't see any part numbers on the connectors themselves. There is a set of numbers on each cable but that ai UL info...

Is the trouble with one of the ports or is it happening with all?

It's with every one. I was wondering what version of IOS is everyone using? I am using 12.0. Is there a specific 2511 ios or can i use the 2500 ios 12.3?

You can use any 2500 IOS for the 2511. It doesn't have its own variant. I'm using 12.2.29b on mine because it has (buggy) support for SSH.

[edit]Had wrong version there. Listed the IPv6 one instead ><[/url]

I would suggest using a Cat5 coupler and a rollover cable to see if you have the octal cables that are wired for a modem connection instead of for the console ports.

Is it possible that the ports on the router are bad? Have you tried both?

Okay! I just tried this cut donw config. R1 connects....the rest refuse connection...was exited for a second. If i use the r1 cable and plug it in it woorks in any slot.....i hAVE 2 BRAND NEW SETS OF OCTAL CABLES..

you need "no exec" under "line 1 16"

any line noise will cause the terminal server to start an exec session, after that it will refuse the connections. You will also need to use "clear line <number>" if you already opened a session then it was improperly closed. You can use "so users" to see what lines already have a session on them.

It is now up and functional, I wil say it seem sto be EXTREMELY sensative to change. But the no exec which i had once before now is working.

I changed my stack around, so the back of my routers where actualy facing me, a little bit easier. Kind of bummed the more i get into this, and realize what equipment is good and what's not.

I would like to drop all the switches except the 3550, if i cna get two more chraply i would be happy. Are there any other things i should be looking at?

And thanlks for everyoens help....talk about frustrating...

tiersten

You don't need to buy more 3550s. Get a couple 2950/2960 running EI and that'd be good enough IMO. Of course, if you've got the money then more 3550/3560's would be very nice to have.

Hi Guys,
Im at wits end here. I have the same issue as mentioned above. Octal cables. After verifying un/pass it just stalls. I have checked the port numbers for the octal cable. I have a C2600 with 4 slots for the octal cable. The cable itself is an RJ45 connector type cable and has numbers on them numbered on it from 1 to 8. The router has ports numbered as follows:
0-7
8-15
16-23
24-31

Maybe I am messing up the cable numbers im not sure.

Point to note:
I have managed to get it working by using an AUX port instead of a TTY port. So the RADIUS server is fine (also removed the radius from the equation and have the same issue). Its just the TTY ports/octal cables that are causing problems.

If someone could help me out, it would be the most stress relieving thing on earth! I am posting configs, without the Access server IP and other sensitive info

PLEASE HELP!

My Access Server is a C2600 and I'm trying to connect to another C2600 via the octal cable

The router has ports numbered as follows:
0-7
8-15
16-23
24-31

you are setting up

ip host router1 2033 172.21.1.1
ip host router2 2034 172.21.1.1

which are ports 33 & 34

Hi,

Ok, when I plug in the octal cable in slot # 2 of the router, I plug in RJ45 #'s 1,2,3 in 3 differnt routers. This makes lights 16, 17,18 light up on the router interface.

Is there some relation to these numbers and to the TTY ports that I am configuring on the router?

I have tried configuring ports in different groups, while keeping the octal cable fixed in one slot. So the different TTY ports I had configured are:
1033, 1034,1035
2033,2034....
3033....
4033....

I was just experimenting to see what works best and I found that the sets 2033/34 and 3033/34 work best for the slot that I have it in. However, with 3033/34 the moment it asks me to authenticate and I put something in, it returns garbled characters. The other two sets did not even let me authenticate. So I assume that I have it plugged into the right slot for the TTY ports I am configuring.

it says that ports 1-33 are either 'non - asynchronous' or 'have no hardware support'. Hence in the "Sh line" command I see ports 0-33-34 all the way to 91

so TTY port 33 is my first available TTY port before that I dont see anything except the console => port 0 and 64 is my last TTY port. After that, the VTY ports start and so on...

Does that make sense? If not, Ill try and explain it little better. Its weird, I havent come across something like this before. Any help is much appreciated!

Cheers!

Hi,
That link is great to give you a good idea of whats going on, I have read through it before. Its possible my fatigued mind is missing things, could you please tell me if this is right:

since TTY port 33 is the first available TTY port for me (and 64 the last which makes 32 in all), does it correspond to interface 0 on the access server as the ports there are 0-31 (which makes 32 in all)?! And does this then need to be configured so that they essentially map to each other?

move the octal cable to ports 0-7 and change the host entry to reflect 2000-2007 and then connect the other end to the console port of another device and see if that works.

edit: if ports 0-7 belong to line 33-40 then change the appropiate entry.

will try that in a few days when im back in the lab...i doubt it will work..ports 1-32 do not even show up in 'show line' as you can see..i can only see lines 33 onwards...

I edited my last post. Edit your post on running config to take out all the type 7 passwords as that password is easy to decrypt.

on the 2600 the NM-32a is in slot 1/0 which will map to lines 33-64. Use 2033 as the port number for the first line, 2034 for the second.

I did edit my running config..but its ok i wasnt going to use those passwords in the final product...

this is the physical layout of the slots on the router:

24-31

16-23
======== =========

8-15

0-7
======== =========

so currently i have it connected in the slot that says 16-23...

when i get back i will try two things:
1) put it in slot 0-7 and config the TTY ports as 4033 and 4034
2) put it in slot 0-7 and config the TTY ports as 2033 and 2034

although im pretty sure i have tried the 2nd option maybe i did something wrong, will try that again

thanks for all the suggestions...much appreciated
