Hi,
Does IOS XR support reverse telnet? Can I connect from an AUX from one ASR9000 to a CON from another ASR9000?
Tks.

Regarding the AUX port on the ASR9k, unfortunately it is not an asynchronous port. The aux port in IOS XR has a very particular purpose; it is intended as the debug line of last resort. If there is a significant problem with the box which is making other access mechanisms (XML, vty, console) difficult to use then the aux port will instead be used. So you cannot reverse telnet through the AUX port like you could on IOS platforms.
Normally reverse telnet is done to the console port using terminal server. I dont think you are looking for that.
Hope this answers your questions.

Is the AUX port still for this purpose or has something changed in later IOS-XR?
We would like to use the AUX on our ASR9K (9904, RSP880-TR) to connect to a external device on it's console port.
I am not quite getting to work so I suspect that AUX is still for the last resort purpose?
Thanks in advance.

thanks for the answer, we didn't need it for the ASR installation. I needed a temporary connection to a console port on another device. And I saw that some other IOS-XR devices was able to do this.
Anyway, we solved the problem in another way. :)
