ip arp inspection validate
The allow-zeros keyword interacts with ARP access control lists (ACLs) in this way:
• If you configure an ARP ACL to deny ARP probes, they are dropped even if the allow-zero keyword
is specified.
• If you configure an ARP ACL that specifically permits ARP probes and configure the ip arp
inspection validate ip command, ARP probes are dropped unless you enter the allow-zeros
keyword.
The no form of the command disables only the specified checks. If none of the options are enabled, all
checks are disabled.
Examples This example show how to enable source MAC validation:
Switch(config)# ip arp inspection validate src-mac
You can verify your setting by entering the show ip arp inspection vlan vlan-range privileged EXEC
command.
