Configuring an
ARP ACL
Use the Security > ACL (Configure ACL - Add Rule - ARP) page to configure ACLs
based on ARP message addresses. ARP Inspection can then use these ACLs to filter
suspicious traffic (see “Configuring Global Settings for ARP Inspection” on
page 349).
Parameters
These parameters are displayed:
◆ Type – Selects the type of ACLs to show in the Name list.

IPv4 address. Use “Any” to include all possible addresses, “Host” to specify a

with the Address and Mask fields. (Options: Any, Host, IP; Default: Any)
◆ Source/Destination IP Address – Source or destination IP address.

addresses, “Host” to indicate a specific MAC address, or “MAC” to specify an
address range with the Address and Mask fields. (Options: Any, Host, MAC;
