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
received by a system-guard-enabled port exceeds the set threshold, the port is
regarded to be under attack. The switch then limits the rate of the port and resumes port
checking operation after a specific period elapses.
