my question is simple: if I am logged into a Cisco router via console or ethernet in priviledged mode, is there a command to initiate a connection through the local AUX port to a nearby console port of another router/switch?

(alternatively, could I accomplish this if I configured reverse telnet on the local router and then type the command "telnet local_loopbackIP 2xxx" port?)

Thanks.

Yes, just telnet to a local (up) interface using port 2001. Aux 0 is (always?) line 1.

int loopback0
 ip address 192.168.1.1 255.255.255.255
!
line aux 0
 transport input all
 transport output all

Telnet 192.168.1.1 2001.

    show line to find the tty for aux. In one case, mine is 161. – Ricky Sep 17 '14 at 20:17
  • Thanks, Ricky. I was trying to find an example (on my gear) where the aux was something other than line 1. What platform has it as line 161? – Ryan Sep 18 '14 at 12:41
