User Guidelines
There are no user guidelines for this command.
Example
console(config-if-Gi1/0/3)#ip arp inspection trust
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.
