“timestamp” represents the time when the ARP scan was detected. For example,
“2008-01-23 16:23:10” represents that the ARP scan was detected at 16:23:10, Jan 23,
2008.

IP-guard
IP-guard Overview
As is known to all, many hacker attacks and the network virus invasions begin
with the network scanning. To this end, a large amount of the scanning packets
take up the network bandwidth, leading to the abnormal network
communication.
Ruijie Layer-3 device provides the IP-guard function to prevent the attacks from
the hacker and the virus such as “Blaster”, reducing the CPU burden of the
layer-3 devices.
There are two types of the IP packet attack:
Scanning the destination IP address change: not only consumes the
network bandwidth and increases the device burden, but also is a prelude
of the hacker attack.
