I have a 2911 configured as a terminal server with a dual-port asynchronus card (16 port), and an OCTO cable
When I try to reverse telnet to a device off one of the cisco devices (firewalls, routers, etc.), I get this
CA-2911-TERMINAL-01#telnet 10.12.12.1 2003
Trying 10.12.12.1, 2003 ... Open
Password OK
and it doesn't go any farther. I have tried multiple port configurations, but haven't been able to figure this out. Here is the config
ip host EXT-SW01 2003 10.12.12.1
ip host EXT-SW02 2004 10.12.12.1
ip host FW1 2005 10.12.12.1
ip host FW2 2006 10.12.12.1
ip host NS1 2007 10.12.12.1
ip host NS2 2008 10.12.12.1
interface Loopback0
description used for reverse-telnet
ip address 10.12.12.1 255.255.255.255

If I do a show line I see

Figured it out -I was using port 1 on the cable when I should have been using port 0 --stupid mistake lol
always check the physical layer!
