command is used to enable the ARP Defend function. To
disable the ARP detection function, please use
"pq

ctr"kpurgevkqp"
command.
ARP Attack flood produces lots of ARP Packets, which will occupy the
bandwidth and slow the network speed extremely. With the ARP Defend
enabled, the switch can terminate receiving the ARP packets for 300 seconds
when the transmission speed of the legal ARP packet on the port exceeds the
defined value so as to avoid ARP Attack flood.
