ASA5520 reverse telnet problem

nenadl · ‎12-25-2014

Hi all,

I have a problem with ASA5520 and reverse telnet. I recently upgrade IOS on ASA5520, asa921-k8. Problem is that cisco has latest IOS version asa91x.... for this platform.

I have 7201 on remote site, and connect his aux to asa console. When I do telnet to specific port, this is output:

This is run over and over. I just can't enter a ROMMON mode of ASA. I have older IOS on flash which works.

I don't know what to type to enter in rommon mode. I tried every combinatios of characters but nothing. I used Putty, SecureCRT.

Any idea?

Nenad

So ESC isn't working during boot? FYI 9.2 is not supported on non-X ASA chassis (which I'm sure you have now figured out). You can also try changing the escape sequence so ESC will work. Check this link on how to change that.

Hope it helps.

Hi Collin, nothing works. Yes I figured out when I boot asa :) I also tried whith escape character but nothing. I thing that something is wrong whith AUX port on 7201, beacause I cant send anything through cable.
