CISCO1921/K9 terminal server problem

Jan Rolny
Level 3
Level 3

Hi,

i have router 1921/k9 configured as terminal server with HWIC-8A card.

Problem is that one of serial lines where I have ASA connected (to console) is trying authenticate all the time to ASA.

Output seems like this:

1921#host asa1

Trying asa1 (1.1.1.1, 2005)... Open

and so on .....

Problem is solved after reboot of router. I tried reset line and it does not work. I would like to stop this flood authentication but I have no idea how. Is it possible that it is HW failure or bug?

Thanks for any advice.

Do you have "no exec" configured on this line where the problem happens?

Perhaps if you post the config we might find something to suggest.
