a trap message to the SNMP agent and the Switch log when an ARP packet is received that doesn't match the IP-
MAC-port binding configuration set on the Switch.

Description
This field will enable and disable the sending of trap log messages for IP-MAC-port binding.
When Enabled, the Switch will send a trap log message to the SNMP agent and the Switch
log when an ARP packet is received that doesn't match the IP-MAC-port binding
configuration set on the Switch.
Use the pull-down menu to enable or disable the DHCP Snooping State for IP-MAC-port
binding.
When this is Enabled, the Switch will filter ARP packets which have unauthorized sender
MACs, IP addresses, and ingress ports. ARP inspection is only active on IP-MAC-port
binding-enabled ports.
Enter the ports for which the ARP check function has stopped. This will allow recovery, or an
unfreezing, of the ARP check on the ports listed in this field. Alternatively, tick All to force the
recovery of all learning ports.
