Parameters
time: Sets the aging time for ARP attack entries, in the range of 60 to 6000 seconds.
Examples
# Set the aging time for ARP attack entries to 60 seconds.

[Sysname] arp source-mac aging-time 60
arp source-mac exclude-mac
Use arp source-mac exclude-mac to exclude specific MAC addresses from source MAC-based
ARP attack detection.
Use undo arp source-mac exclude-mac to remove the excluded MAC addresses from source
MAC-based ARP attack detection.
Syntax
arp source-mac exclude-mac mac-address&<1-10>
undo arp source-mac exclude-mac [ mac-address&<1-10> ]
Default
No MAC addresses are excluded from source MAC-based ARP attack detection.

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