Parameters
mac-address&<1-10>: MAC address list. The mac-address argument indicates an excluded MAC address
in the format H-H-H. &<1-10> indicates the number of excluded MAC addresses that you can configure.
Usage guidelines
If you do not specify any MAC address, the undo arp source-mac exclude-mac command removes all
excluded MAC addresses.

# Exclude a MAC address from source MAC based ARP attack detection.
<Sysname> system-view
[Sysname] arp source-mac exclude-mac 2-2-2
arp source-mac threshold
Use arp source-mac threshold to configure the threshold for source MAC address based ARP attack
detection. If the number of ARP packets sent from a MAC address within 5 seconds exceeds this threshold,
the device recognizes this as an attack.
Use undo arp source-mac threshold to restore the default.
