Display the Logging Buffer and the Logging
Configuration
To display the current contents of the logging buffer and the logging settings for the system, use the show logging
command in EXEC privilege mode. When RBAC is enabled, the security logs are filtered based on the user roles. Only the
security administrator and system administrator can view the security logs.
