Arp Detection Enable - HP 6125G Command Reference Manual

vlan vlan-id: Specifies the VLAN where the rule applies. The vlan-id argument is in the range of 1 to
4094.
Description
Use arp detection to set a rule for user validity check.
Use undo arp detection to restore the default.
By default, no rule is set for user validity check.
User validity check inspects each ARP packet received on an ARP untrusted interface against the
configured rules. If a match is found, the ARP packet is processed according to the matching rule. If no
match is found, the device checks the packet against static IP Source Guard binding entries, the DHCP
snooping entries, 802.1X security entries, and OUI MAC addresses in turn.
