Can AUX port be attached to a console port?
Even though the AUX port is a “line”, it could be attached to and “interface” that would behave just line any other interface on the router and route traffic between the two routers. The console port can only be configured as a line and can not be attached to an interface.
How many pins does AUX port use?
The AUX port uses many more pins. In addition to the data pins (TX/RX) and ground, the AUX port also uses the other modem control pins: CTS (clear to send), RTS (ready to send), DTR (data terminal ready), and DSR (data set ready).
How do I connect a DCE to a Cisco router?
Refer to Cisco Technical Tips Conventions for more information on document conventions. Cisco routers either have RJ-45-based or DB-25 DCE/DTE console and AUX ports. You can connect either a terminal (DTE) or a modem (DCE) to these ports. In either instance, you need both an RJ-45 cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 connector.
What does AUX port mean in Cisco Network Academy?
In the Cisco Network Academy labs we configure the console port as it is path into the router if you have physical access. BUT WE LEAVE THE AUX PORT UN-CONFIGURED! This means that if you were to get physical access to the router, you can plug into the AUX port and boom! You would have user exec (non-privileged) access to the router.

The AUX port is still an active port (line) on the back of a router that must not be ignored. In the Cisco Network Academy labs we configure the console port as it is path into the router if you have physical access. BUT WE LEAVE THE AUX PORT UN-CONFIGURED This means that if you were to get physical access to the router, you can plug into the AUX

Difference Between Console Port and Aux Port

The original purpose of the AUX port was to serve as an out-of-band access method into the router. Cisco would ship you a DB-25 adapter that was made to be used with the rollover cable to attach the AUX port to an analog modem. The console port only supports the data pins: TX, RX, and ground. This works great when you are just using a local compute

Modems Are Old School, How Do We Do OOB Today?

There is still a big demand for our of band access to routers. If you have a router at a large office and your WAN link goes down, you need to troubleshoot. Today, modems have been replaced by cellular as the OOB technology of choice. There are many companies that sell these products, also referred to as console servers. These boxes will use a cell

Is There Anything I Can Still Do with My Aux Port?

Next, there is a feature that you can configure on the AUX port called Reverse Telnet. Before configuring your AUX port for reverse telnet, you will have to build a cable that will allow you to connect the aux port to your other serial device. This means that you are going to have to find the right pinout configuration to go from the RJ-45 AUX port
