Providing Data to Your Technical Support Representative
C-524
In order to use the router’s auxiliary port for remote access, you must include several configuration
commands. The required commands are as follows:
line aux 0
modem inout
If you are using software prior to Cisco IOS 11.1, set the modem options as specified for the console
port.
If you are using Cisco IOS 11.1 or later, you do not need to set the modem configuration manually,
but you must include the modem autoconfigure discovery line configuration subcommand.
Note You can also refer to Chapter 16, “Troubleshooting Dialin Connections,” for additional
related information.
Providing Data to Your Technical Support Representative
If you need technical assistance with a Cisco product that is under warranty or covered by a
maintenance contract, contact Cisco’s Technical Assistance Center (TAC) to open a case. Contact
the TAC with a phone call or an e-mail message:
North America: 800-553-2447, e-mail: tac@cisco.com
Europe: 32 2 778 4242, e-mail: euro-tac@cisco.com
Asia-Pacific: 61 2 9935 4107, e-mail: asiapac-tac@cisco.com
When submitting information to your technical support representative, electronic data is preferred.
Electronic data significantly eases the transfer of information between technical support personnel
and development staff. Common electronic formats include data sent via electronic mail and files
sent using FTP.
If you are submitting data to your technical support representative, use the following list to
determine the preferred method for submission:
The preferred method of information submission is via File Transfer Protocol (FTP) service over
the Internet. If your environment supports FTP, you can place your file in the incoming directory
on the host cco.cisco.com.
The next best method is to send data by e-mail. Before using this method, be sure to contact your
technical support representative, especially when transferring binary core dumps or other large
files.
If you use e-mail, do not use encoding methods such as binhex or zip. Only MIME-
compliant mail should be used.
Transfer via a PC-based communications protocol, such as Kermit, to upload files to Cisco
Connection Online (CCO). Again, be sure to contact your technical support representative before
attempting any transfer.
Transfer by disk or tape.
The least favorable method is hardcopy transfer by fax or physical mail.
