Sorry in advance for another topic about this but I have gone through every other related topic and nothing has helped.
So I have a c819hg and a c2960cx. I want to do reverse telnet from 819 aux port to c2960 console port. I plug in a rollover cable rj45 to rj45 between them.
I have started with disabling the console port on the 819 (it is necessary to get the aux available since they share the physical port)
#819
line con 0
no modem enable
Then I put in the necessary configuration for the aux line:
#819
line aux 0
access-class AUX-REVERSE-TELNET in
login authentication AUX-AUTHEN
no exec
transport input telnet
transport output none
stopbits 1
Nothing special on the console port of the 2960
#2960
line con 0
privilege level 15
password 7 ###########
login authentication LOCALAUTH
stopbits 1
What happens is that I get connection, if I have authentication requirments configured on 819 then I get the prompt to provide this. After this nothing happens. Since I get the authentication prompt from the 819 I can surmise that there is no problem with the access list or the authentication setup. I have also tried removing them.
If I check the aux line for 819 it looks okay:
#819

On the 2960 there is no activity at all on the line.
819 has a serial interface as well. I have done basically the same thing there but reverse telnet over the serial interface instead (with a bunch of cables and adapters in between to get the pinlayout correct) and that works without any issues. The problem is I want to use a rj45 to rj45 and not this cable mess for a more permanent solution.
Any help would be greatly appriciated!
