Would again appreciate any help on the use of access server, as i came accrss this in books and CBTs that it could save me a lot of time of recabling.
Can anyone please explain how this works and any recoomendation module? (Heard of router 2511 as one option)

Hi, [Pls RATE if HELPS]
Refer the Details below:
Configuring a Cisco Router as Terminal Server:
---------------------------------------------
You want to have console connectivity to all your routers at the same time. By using a terminal server (2509-2512 router range) we can accomplish this.
To use a terminal server we need a 2509/2510 8 lines or 2511/2512 16 lines router and 1 or 2 octal cables.
The first thing we do is create a loopback interface that will be used for the reverse telnet sessions from the other devices.
Router(config)#interface loopback0
Router(config-if)#ip address 172.16.1.1 255.255.255.255
Now we add the devices that are connected to this router [octable cable to each console port]
Router(config)#ip host hostname 2001 172.16.1.1
Router(config)#ip host hostname2 2002 172.16.1.1
The previous commands lets you use the hostname of the device to access it on it's console port. The portnumber is made of the following 200x where x is the nr on the octal cable going to that device. Depending on the type of router you use for terminal server you can have either 8 or 16 devices hanging of it.
Now that the router is configured we use the following commands to navigate.
- to access a device
telnet 172.16.1.1 2001
- to switch between active sessions
ctrl-shift-6-x will bring you back to terminal server
show sessions will display the active sessions
entering a number of a session will let you access that session
- to disconnect a session
use the disconnect command
PLEASE RATE if HELPS

Do you have to use a 2500 series to create an access-server? I have some 2600 routers that I could use. What type of card would I need to install to make an access-server possible.

Hi Tyler,
No its not a must, the 2500 is simply the cheapest option, i use 2600 routers with async port adapters (NM-16A), plus CAB-OCTAL-ASYNC cables.

I've got a weird problem and wondering if my config is incorrect in regards to an Access Server. When I try to connect to another device it just hangs on:
Router(boot)#R2
Trying R2 (1.1.1.1, 2002)... Open
and then I have to use ctrl shift 6 X to get back into the AS
Though sometimes it works when i start changing plugs around and then plugging it back. I've got a cisco 2511 AS and heres my config:
interface Loopback0
ip address 1.1.1.1 255.255.255.255
no ip directed-broadcast
no ip route-cache
ip host R1 2001 1.1.1.1
ip host R2 2002 1.1.1.1
ip host R3 2003 1.1.1.1
ip host R4 2004 1.1.1.1
ip host R5 2005 1.1.1.1
ip host R6 2006 1.1.1.1
ip host R7 2007 1.1.1.1
ip host R8 2008 1.1.1.1
line con 0
exec-timeout 0 0
logging synchronous
line 1 16
no exec
transport input all
line aux 0
transport input all
line vty 0 4
!
end
Any ideas on why it would be hanging?
