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 logged in the internal buffer.
Configuration Task List for System Log Management
There are two configuration tasks for system log management:
● Disable System Logging
● Send System Messages to a Syslog Server
● Change System Logging Settings
● Display the Logging Buffer and the Logging Configuration
● Configure a UNIX Logging Facility Level
● Enable Timestamp on Syslog Messages
● Synchronize Log Messages
● Audit and Security Logs
