Prevent ARP cheating
: ARP spoofing prevention checks the source IP address of an ARP packet on the port, to
determine whether the IP address matches the configured IP address of important equipment. If yes, the system discards
the packet to prevent the user client from receiving incorrect ARP responses. Therefore, the IP address for packet filtering
on the port need to be set. Set
Equipment IP

IP address, and click
Add
. The added equipment IP address and the port for filtering are displayed in the list. Click the edit

Equipment IP
