Concept Guide

CONFIGURATION mode

service timestamps [log | debug] [datetime [localtime] [msec] [show-timezone] | uptime]

Specify the following optional parameters:

– datetime: You can add the keyword localtime to include the localtime, msec, and show-timezone. If you do not add

the keyword localtime, the time is UTC.

– uptime: To view time since last boot.

If you do not specify a parameter, the system congures uptime.

To view the conguration, use the show running-config logging command in EXEC privilege mode.

To disable time stamping on syslog messages, use the no service timestamps [log | debug] command.

Enabling Secure Management Mode

The Switch supports the secure management mode on Dell Networking OS. It is a congurable mode where the access of Chassis

Management Controller (CMC) is bypassed. With this change, CMC is not allowed to congure or view Networking information, upgrade

software, or view the conguration.

Use the conguration command, enable secure to put the switch into secure mode. For the changes to take eect, save the

conguration 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 le 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 switch:

• Connect to the Switch.

• Firmware updates for the Switch.

• Setting or viewing network interface conguration like Internet Protocol (IP) address, network mask, gateway, and Dynamic Host

Conguration Protocol (DHCP).

Secure mode limits the ability to view or modify conguration, or upgrade software to the switches 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 eect, save the conguration and reboot the

system. Once the system exits secure mode, all the restrictions are gone. CMC is able to learn the status when it readsswitch.xml and

lifts the restrictions for the switch.

NOTE

: When you add a switch in an existing stack which is in secure mode, reboot the new switch twice for it to enter into the

secure mode.

Enabling Secured CLI Mode

The secured CLI mode prevents the users from enhancing the permissions or promoting the privilege levels.

• Enter the following command to enable the secured CLI mode:

CONFIGURATION Mode

secure-cli enable

After entering the command, save the running-conguration. Once you save the running-conguration, the secured CLI mode is enabled.

If you do not want to enter the secured mode, do not save the running-conguration. Once saved, to disable the secured CLI mode, you

need to manually edit the startup-conguration le and reboot the system.
