ACLs, first create an access list containing the required permit or deny
rules, and then bind the access list to one or more VLANs using the ip arp
inspection vlan command.

◆
When you create a new ACL or enter configuration mode for an existing
ACL, use the permit or deny command to add new rules to the bottom
of the list. To create an ACL, you must add at least one rule to the list.
◆
To remove a rule, use the no permit or no deny command followed by
the exact text of a previously configured rule.
◆
An ACL can contain up to 128 rules.
