Hi,
I have a 3620 with a NM-32A cabled to numerous Cisco consoles with CAB-OCTAL-ASYNC cable to each console port.
CONSOLE SERVER:
!
interface Ethernet1/0
ip address 192.168.10.180 255.255.255.224
no ip directed-broadcast
!
ip host SWITCH4 2001 192.168.10.180
!
line 1 32
session-timeout 20
no exec
exec-timeout 0 0
transport input telnet
transport output pad v120 telnet rlogin udptn
!
SWITCH4:
aaa authentication login default local-case
aaa authorization exec default local
username user password Pass
enable secret SECRET
!
!
line con 0
exec-timeout 0 0
transport preferred telnet
!
CONSOLE#teln SWITCH4
Trying SWITCH4 (192.168.10.180, 2001)... Open
User Access Verification
Username: user
Password:<Pass>
_
This times out....I then auth again and sometimes get in, sometimes not. Same behaviour across 4 out of 13 devices (so far).....!!
Has anyone had similar problems?
Thanks,
Mark

I suggest, as an experiment, that you remove this line from the config and see if the behavior improves:
aaa authorization exec default local
I do not see that this is doing much for you (at least in the small amount of configuration that you posted) and potentially could cause symptoms such as you describe. If the behavior does improve you might leave it out or you might change it to this:
aaa authorization exec default if-authenticated

Hello,
This is the normal behavior as AAA is configured on your console server, and by default the authentication configured is applied on all lines, this behavior is not what you require on a terminal server, so
On the console server, configure:
aaa authentication login NOAUTH none
Under the NM-32 lines, configure:
login authentication NOAUTH

Thanks to Rick, Wissam for your help.
I took of Authentication from the lines as you suggested and all is working well.
Thanks again,
Mark
