Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

The MXL Switch supports the secure management mode on Dell Networking OS. It is a configurable mode where the access of Chassis Management Controller (CMC) to MXL is bypassed. With this change, CMC is not allowed to configure or view MXL Networking information, upgrade MXL software, or view MXL configuration.

Use the configuration command, enable secure to put the switch into secure mode. For the changes to take effect, save the configuration and then reboot the system. The switch automatically enters the secure mode following reboot. Check the status of the switch in the .xml file that it generates during bootup. The CMC reads the switch.xml file and sets the secure mode. It also disables the CMC Command Line Interface (CLI) or Graphical User Interface (GUI) from being able to do the following on the MXL:

• Connect to the MXL Switch.
• Firmware updates for the Switch.
• Setting or viewing network interface configuration like Internet Protocol (IP) address, network mask, gateway, and Dynamic Host Configuration Protocol (DHCP).

Secure mode limits the ability to view or modify configuration, or upgrade software to the MXL's external USB console port and internal management network only. CMC continues to have access to other properties like power status and system health.

To disable the secure mode, use no enable secure command. For the changes to take effect, save the configuration and reboot the system. Once the system exits secure mode, all the restrictions are gone. CMC is able to learn the status when it reads switch.xml and lifts the restrictions for the switch.
