Cannot return back to Cisco 2511 after telnet?

I have CCIE lab at home (14 Cisco routers/switches). I am using Cisco 2511 as terminal (serial) server for accessing all other devices’ console. The loopback IP address has been created; ip host R4 on 8th port has been defined. I am able to connect to router R4 but I cannot return back to Cisco 2511. The same result is for every router on every port...

TermServer#R4      

Trying R4 (172.21.1.1, 2008)... Open

Router>

Router>

Router>

Router>

Router>exit     

Router con0 is now available

Press RETURN to get started.

Router>exit

Router con0 is now available

Press RETURN to get started.

It seems like sequence Ctr Shift 6 x doesn’t work. I tried with Secure CRT, Putty on Vista and Hyper terminal on XP but the outcome was always the same…This is the configuration of 2511.

TermServer#sh run

TermServer#sh running-config

Building configuration...

Current configuration:

!

version 12.0

service timestamps debug uptime

service timestamps log uptime

no service password-encryption

!

hostname TermServer

ip subnet-zero

ip host R4 2008 172.21.1.1

line con 0

transport input none

line 1 16

session-timeout 1

no exec

transport preferred none

transport input all

line aux 0

line vty 0 4

!

End

After 1 minute the session is auto terminated because of session-timeout 1 command.

Any suggestion what might be a problem?

Hi Franjo,

In your example, after login to R4 if you want to get back to the 2511, hold down "ctrl+shift+6" at the same time than "x".

Hi Reza,

I tried with small pause between Ctrl-Shift-6 and X but nothing has happened... I tried this with English keyboard.

Thanks anyway.

Re: Cannot return back to Cisco 2511 after telnet?

Hi Ganesh
There is no any error. It simply doesn’t react. Like I didn’t type anything… Please check the log file attached. Can you see those blank lines; these are the moments when I typed Ctrl-Shit-6, x sequence.
Thanks for helping me!
Franjo
