Monitoring Dynamic ARP Protection
When dynamic ARP protection is enabled, you can monitor and troubleshoot the validation of ARP
packets with the debug arp protect command. Use this command when you want to debug the
following conditions:
■ The switch is dropping valid ARP packets that should be allowed.
■ The switch is allowing invalid ARP packets that should be dropped.
