Security logs are very important for locating and troubleshooting network problems. Generally, security 
logs are output together with other logs. It is difficult to identify security logs among all logs. 
To solve this problem, you can save security logs into a security log file without affecting the current log 
output rules.  
The configuration of this feature and the management of the security log file are separate, and the 
security log file is managed by a privileged user.  After logging in to...

Configuring synchronous information output 
The output of system logs interrupts ongoing configuration operations, and you have to find the 
previously input commands before the logs. Synchronous information output can show the previous input 
after log output and a command prompt in command editing mode, or a [Y/N] string in interaction 
mode so you can continue your operation from where you were stopped. 
To enable synchronous information output:
