Chapter 3 System-guard Configuration
3.1 System-guard Overview
The system-guard function checks system-guard-enabled ports regularly to determine
if the ports are under attack. With this function enabled, if the number of the packets

regarded to be under attack. The switch then limits the rate of the port and resumes port
checking operation after a specific period elapses.

z Enabling the system-guard function
