What is the difference between these two gratuitous ARP commands?

[rweir0001]

If I want to disable gratuitous ARP on my switches what is the difference between these two ARP commands:

no ip gratuitous-arps

no ip arp gratuitous

If I run "no ip arp gratuitous" the IOS will ask me to choose between "local" and "none". After I issue the command it does not show up in my running-config, but the "no ip gratuitous-arps" command does.

ip gratuitous-arps

To enable the transmission of gratuitous Address Resolution Protocol (ARP) messages for an address in an address pool if the transmission has been disabled, use the ip gratuitous-arps command in global configuration mode.

ip arp gratuitous

To enable the gratuitous Address Resolution Protocol (ARP) control on the router.

local: Allow only local gratuitouss arps over the same subnet.
none: Discard the gratuitous arp.

Julio,

So if I configure the "ip arp gratuitous none" command on my switches they will DROP all gratuitous ARP packets, correct?
