Parameter
rate-limit: Specifies that system-guard is achieved by limiting the rates of attacked ports.
interval-time: Interval to perform the system-guard operation.
threshold: Threshold in terms of the number of the packets received by the management port within the
period specified by the interval-time argument.
Timeout: Time period within which an attacked port is under control.
Description
Use the system-guard mode rate-limit command to implement the system-guard function by means
of port rate limit. A switch checks the management port for the number of the received packets once in
each period determined by the interval-time argument. If the number exceeds the threshold, the switch
considers the specific ports to be attacked ports and applies the port rate limit to these ports. The port
rate limit is invalidated after the time specified by the time-out argument elapses.
