Dynamic ARP Inspection

[gjortega]

Does anyone know how to enable or configure Dynamic ARP Inspection on a 6450? I have reviewed all the documentation with no results.

Thanks

in ALE security docu I have found the following hint:

DHCP Snooping with ip-source-filter is an equivalent of two Cisco features enabled at the same time: Dynamic ARP Inspection (DAI) with IP Source Filter.
For differences see TKC article 000006888.
DHCP Snooping with ip-source-filter can be also used to avoid CAM overflow attacks.

And DHCP snooping you will find in the guide.
