Use of the AUX port on a CISCO router

Here is what I found in a Cisco router manual. The one you are using is the 1700 Series?

Auxiliary port (AUX):
RJ-45 jack connection with EIA/TIA-232 interface (connector compatible with AUX port of the Cisco 2500 series); asynchronous ETTD2 series with all modem commands (CD 3, DSR 4, RTS 5, CTS 6); data transfer rates in asynchronous serial mode up to 115.2 kbits/s.

Console port:
RJ-45 jack connection with EIA/TIA-232 interface (connector compatible with console ports of the Cisco 1600 and 2500 series); asynchronous ETTD series; transmission / reception rate up to 115.2 kbits/s (default 9600 bits/s, not on a data port); note: no hardware bidirectional exchange protocol such as RTS/CTS.

Hello,

The AUX port is used to admin in "console" a router by connecting a MODEM to it, it seems.
It is mainly used for training at Cisco but very rarely in companies, actually.

Example:
The PC is in Paris ... the routers are all in a data center in the US ... the AUX port is used to connect in console from Paris (which is impossible from the console port, I believe).
For this, you need equipment (such as a router) with serial ports properly configured to connect to the AUX ports.
You also need to configure the AUX port (but I don't know how ...).

So there, I have no idea about that, check the Cisco website.
But if you want to connect remotely to the PC, configure Telnet access and then connect to it via Telnet.

It's a serial port to connect a terminal and enter the basic configuration of the router; the rest is done through the network and there is no longer any reason to access this port.
The only way I see is to connect the AUX port of the router to the COM serial port of a PC, access this PC over the network, and its COM port through a terminal emulator, like HyperTerminal.

Thank you everyone for your cooperation,

So the AUX port is used to manage the router remotely. But I just found out that it does not offer all the configuration options.

For example, we cannot proceed with password recovery via this port. The only solution in this case is to connect in console mode.

See you!

So the AUX port is used to administer the router remotely
no, no
we can do it, but that's not the purpose.

Little correction ...
it is possible to manage devices remotely via the console port, you just need to get a console port switch ... (I’m actually looking for a good model .... if anyone can recommend a nice piece of equipment, I'm interested)

that’s how operators intervene at remote sites when the network crashes ...
(they bounce off a different network, the console port network ...)
Anyway, there you go

Thank you, Ludoo, but how can I manage the router remotely via the AUX port and with what type of cable? And what type of equipment can be connected to this port?
