Hello,
I recently bought a second hand Cisco AS2511RJ.
I setup the below AS2511 configuration which is working well except I cannot reverse Telnet into my 2 2960 switches
My equipment model numbers are as follows;
R1: 1841
R2: 1841
R3: 1841
S1: 2960
S2: 2960
S3: 3750
I enterered "transport input telnet" under the vty lines on each of the above devices, but I cannot access S1 or S2.
I receive the following messages
Trying S1 (10.1.1.1, 2009)...
% Connection refused by remote host
Trying S2 (10.1.1.1, 2010)...
% Connection refused by remote host
If anyone could please help me out, I would greatly appreciate it.
Thank you very much

Hi,
Can you post "sh run" or the config for "con 0" form both S1 and S2?
It shoudl look like this
line con 0
exec-timeout 0 0
password
logging synchronous
login

line vty 0 4
login
!
line con 0 is for direct connect using a console cable, the vty ports are for network access/telnet so configure the vty as you did for the line con 0.

Mark,
The setup you are describing should be as Reza's post. (+5 R)
S1-CONS ---------- 2511-port 9
S2-CONS ---------- 2511-port 10
So you need the correct settings on the 2960 console ports.
This link is a good place to see an example.
