Hi timgreen7077,

The Aux port is used in a similar way to the console port - for configuration of the router. You could connect a console cable to the aux port and manage the router in a similar way, but the AUX port is intended for connecting a modem for remote administration. (E.g. connected to a modem, it would allow remote administration of the router remotely if the connection to the office dropped etc.)

Similar to how you would configure the password for console logon, you can (should) also set the AUX password.
From global configuration mode:
line aux 0
password admin1
login

Open in new window


Hopefully this answers your question!

The aux port is also used if you want to reverse telnet or ssh into another device. You would connect a rollover cable from the router's aux port to another router or switches console port. After configuring the aux port you could then telnet or ssh into the router and then console into the second router or swith. This is useful during changes where you want to have console access to devices that needs rebooting or may have possible network disconnects.
