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.
