The AUX on a 2509 is line 9, so you can establish a reverse-telnet connection to it by opening a telnet session to port 2009/tcp.

im trying to connect but im just getting a "password ok" message with nothing else. i using a rollover cable to connect to the aux port but im reading that may be the incorrect way.

im i suppose to use an ethernet cable? what is the official way to connect?

thanks

Jody LemoineNetwork ArchitectCommented:
It depends on what you're connecting to. If it's the console of other Cisco devices, then a rollover cable is appropriate. Keep in mind that you're connecting to a serial port, so once the password is accepted, you'll need to hit enter a couple of times to get a response. If that fails, a mismatch of the serial settings between the AUX Port and the device you're connecting to can mess things up.

Try connecting the AUX to CON on the 2509 with the rollover and see if that responds.

how is that possible? a rollover cable has a serial end and an RJ45 head.

Jody LemoineNetwork ArchitectCommented:
You have a console cable. A rollover cable has two RJ-45 ends and the cable rolled over between them, hence the name. We may be able to use the console cable for this, but there may be a DTE/DCE mismatch. If you want to try it this way, make sure you have a terminal application and connected to your COM port so that you can see what's coming through. The terminal application should display what you type into the telnet session after you connect.

i understand you helping me making this work any how. However, the console port is already being used. My question related to how to connect and use the aux port in case my console port locks up in my access server.

i dont have this "2 head-rj45 rollover cable".

thanks,

Jody LemoineNetwork ArchitectCommented:
Ah.  That's completely different.  To be fair though, anything that locks the console port has likely locked the entire router so access via the aux port won't really help. You should be able to do it by having the following in your aux config and then connecting to aux the way you would to the console:

line aux 0
 exec
 default transport input

thanks it worked. I had to disconnect the aux cable, re-scan for hardware changes and for some reason it took it this time. beside your "exec" line it fixed.

thanks again.
