Safeguard Engine Settings 

Periodically, malicious hosts on the network will attack the Switch by utilizing packet flooding (ARP Storm) or other 
methods. These attacks may increase the switch load beyond its capability. To alleviate this problem, the 
Safeguard Engine function was added to the Switch’s software. 

 

The Safeguard Engine can help the overall operability of the Switch by minimizing the workload of the Switch while 
the attack is ongoing, thus making it capable to forward essential packets over its network in a limited bandwidth. 
The Safeguard Engine has two operating modes that can be configured by the user, 

Strict

 and 

Fuzzy

. In 

Strict

 

mode, when the Switch either (a) receives too many packets to process or (b) exerts too much memory, it will enter 
the Exhausted

 

mode. When in this mode, the Switch will drop all ARP and IP broadcast packets and packets from 

un-trusted IP addresses for a calculated time interval. Every five seconds, the Safeguard Engine will check to see if 
there are too many packets flooding the Switch. If the threshold has been crossed, the Switch will initially stop all 
ingress ARP and IP broadcast packets and packets from un-trusted IP addresses for five seconds. After another 
five-second checking interval arrives, the Switch will again check the ingress flow of packets. If the flooding has
