Terminal server on ISR4321

[cmandela]

Am trying to setup a terminal server using isr 4321 and the end routers are NCS5504 but am not able to its shows a number of errors, which I will attach.

i don't tsee any obvious error messages?
except:
    TERMINAL-SERVER-RASDIKA#r3
    % Unknown command or computer name, or unable to find computer address
    TERMINAL-SERVER-RASDIKA#R3
    % Unknown command or computer name, or unable to find computer address

"r 3" (with space) may indicate you want to "resume" an existing session 3
are you sure that is an existing session ?   try "show session"
als you may think you reference a macro but that does not exist on this device

and last your menu only contains a title, but no further options

Hi,

From your term server,

Can you try 

TERMINAL-SERVER-RASDIKA#telnet R3

If you want to short cut the long command to just R3 you will need to write an alias line in the config

conf t

!

alias exec R3 telnet R3

end

Hoe this helps

[Richard Burts]

One of the things that I note in the config is that the async lines include the statement no exec. It may not be all of the problem but I suspect that it is part of the problem.

Big +1 on what @Richard Burts just said. If you don't disable exec on the outbound ports, you will get the routers talking to one another. A reboot or error message from the console of the remote router will make the terminal server think a login session has started on that port, and it will be marked as busy.
