A customized rate limit (in packets per second) can be assigned to the Safeguard Engine’s sub-interfaces as a whole
or to individual protocols specified by the user in the management interface. Be careful when customizing the rate limit
for individual protocols, using this function, as improper rate limits can cause the Switch to process packets
abnormally.
NOTE: When Safeguard Engine is enabled, the Switch will allot bandwidth to various traffic flows
(ARP, IP) using the FFP (Fast Filter Processor) metering table to control the CPU utilization
and limit traffic. This may limit the speed of routing traffic over the network.
