show arpinspection access-list
17-24 DHCP Snooping and Dynamic ARP Inspection
Defaults
None.
Mode
Switchcommand,read‐write.
Usage
ARPACLsareusedtodefinestaticmappingsforDAI.ARPACLsarecompletelyindependentof
ACLsusedforQoS.Amaximumof100ARPACLscanbeconfigured.WithinanACL,a
maximumof20rulescanbeconfigured.
AstaticmappingassociatesanIPaddresstoaMACaddress
onaVLAN.DAIconsultsitsstatic
mappingsbeforeitconsultstheDHCP snoopingbindingsdatabase—thus,staticmappingshave
precedenceoverDHCP snoopingbindings.
