Hi Stephan,

Yes, but you need to know the pin assignment and the appropriate baud rate.

Hi Mohammed,

the baud rate is 9600 und a normal Cisco Console Cable works on the console port of the console server.

I used an normal Cisco Console Cable and a rolled Cable for the connection between the Cisco 2821 and the Lantronix Console Server.

But it doesn't work with "telnet 2001".....the AUX Port is Line 1.

This is the current config from the aux port:

interface Loopback0

ip address


line aux 0

modem InOut

transport input all

speed 9600

stopbits 1


Best regards,

Stephan Brunst

Can you please try to add "no exec" under the line aux 0, then clear the line a couple of times and try again.
