NM-16a console server config

Hi all,

I'm stumbling on a console server setup.

I've read How Async Lines are Numbered in Cisco 3600 Series Routers.

I'm using slot 0 which is ok unless it's a 3660. So my line numbers are 1 - 16.

Line(s) not in async mode -or- with no hardware support:
17-128

I've been reading Configuring a Terminal/Comm Server but I'm still having some problems.

My understanding is I set a loopback to identify the console server(done). Then when trying to connect to the other routers I type their ip host name I set. eg. 2610-1. My console server(3640 NM-16A) open a connection via that port.

ip subnet-zero
ip host 2610-1 2002 10.0.25.1
ip host frs 2001 10.0.25.1
!
!
!
!
interface Loopback2501
 ip address 10.0.25.1 255.255.255.0
 no ip directed-broadcast

ACS#2610-1
Trying 2610-1 (10.0.25.1, 2002)...
% Connection refused by remote host

I think I might need to set up an account on each router so my ACS# can connect to the other routers.

Thank you for reading.

you might have to clear line 2 do sh line and see if line 2 has a * which means its in use. All your ACS does is open the connection to your console port it doesnt check any settings for your console port. Try to telnet 10.0.25.1 2002 and see if that works

Cheers kryolla you're a champion. I should have been looking at the output more closely.

Lines 10 - 12 were in use which are the lines to the routers. Instead of 2001 - 2004 I should have been using 2010 - 2012. The cable was plugged into the other side.
