ip arp inspection validate
Use the ip arp inspection validate command to enable additional validation checks like source
MAC address validation, destination MAC address validation or IP address validation on the
received ARP packets. Each command overrides the configuration of the previous command.
For example, if a command enables source MAC address and destination MAC address
validations and a second command enables IP address validation only, the source MAC address
and destination MAC address validations are disabled as a result of the second command. Use
the “no” form of this command to disable additional validation checks.
