Administrator Guide

NOTE: If the maximum number of VTY lines are more than the concurrent sessions and the same user is attempting

to login second time or more, the system displays the Maximum concurrent sessions for the user reached

message. You are allowed to clear the existing session and login. If you do not want to clear any of the existing

session, the system does not allow any attempt to login since maximum concurrent sessions have reached even

though more VTY lines are available. You are allowed to login as a different user as more VTY lines are available.

The following example enables you to clear your existing login sessions.

DellEMC(config)#login concurrent-session clear-line enable

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-configuration. Once you save the running-configuration, the secured CLI mode is enabled.

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

need to manually edit the startup-configuration file and reboot the system.

Log Messages in the Internal Buffer

All error messages, except those beginning with %BOOTUP (Message), are log in the internal buffer.

For example, %BOOTUP:RPM0:CP %PORTPIPE-INIT-SUCCESS: Portpipe 0 enabled
