The allow-zeros keyword interacts with ARP ACLs in this way:
•
If you configure an ARP ACL to deny ARP probes, they are dropped even if
the allow-zeros 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.
Example
switchxxxxxx(config)#
ip arp inspection validate dst-mac
switchxxxxxx(config)#
ip arp inspection validate src-mac
switchxxxxxx(config)#
ip arp inspection validate ip
switchxxxxxx(config)#
ip arp inspection validate ip allow-zeros
