Cabletron Systems CSX1000, CSX1200 manual Change Defaults to Secure System

USER’S GUIDE

If you experience a problem transferring the file with TFTP, wait about three minutes for the TFTP to fail, delete the incomplete file, and try again.

4.Using Telnet, reboot the system by issuing the command: restart

It should take approximately 3 minutes for the system to restart and install the upgrade.

5.Login via Telnet and type the ver command to confirm that the system software upgraded correctly. If the upgrade did not occur, check the system log with the dr command to find any potential problems, and retry.

CHANGE DEFAULTS TO SECURE SYSTEM

The system is preconfigured with defaults that were designed to make it possible to have your system up and running quickly. After your machine is functioning properly, some of these defaults should be changed to make your system more secure. The following configuration changes are needed to provide this security:

1.Either delete User1 and User2 or change their names and secrets.

Use Dynamic Management’s manage mode to carry out either of these functions. To enter the manage mode, type manage at the system prompt. If you have no need for these types of devices (PPP devices), simply delete these two devices. At the manage mode prompt, enter the following command:

device delete

Follow the onscreen instructions for deleting each device.

To change the preconfigured devices’ names and secrets to secure the access to the system, enter the following command at the manage mode prompt:

device change

Follow the prompts to change the device name and secret for User1 and User2. After you have either deleted or changed the device information, make these changes permanent by entering the commit command

2.Disable TFTP Server.

Disable through Dynamic Management’s manage mode. This will secure important device information. Device information must be secure to prevent unauthorized access to the CyberSWITCH. To disable this access, enter the following command at the manage mode prompt:

tftp change

Then follow the onscreen instructions to disable the TFTP feature.
