Guys, Just like somebody said previously, you need to start breaking things down. ARP. OK...what is ARP? Where does it operate in the OSI stack? It is a layer 2 protocol even though it carries some information about layer 3 in in. So you have your ethernet frame...you have an ethertype value that specifies the next protocol....the ethertype value for ARP is indeed 0x0806.
The way to do this most effectively is to write up something like this: mac access-list extended ARP permit any any 0x0806 0x0000 vlan access-map NoARP deny 10 match mac address ARP action drop vlan access-map NoARP 20 action pass vlan filter NoARP vlan-list <VLANs> On Tue, Oct 13, 2009 at 5:50 AM, Kim Pedersen <[email protected]> wrote: > Hi, > > I believe that the protocol type for ARP is 0x0806.
