Hi Brandon

You have answered to my another mail thread with the subject "ARP
access-list with static". Thx


My question

In Non-DHCP environments, ip dhcp snooping won't work. Hence we need to add
the static IP address/MAC mappings using the arp access-lists for arp
inspection.


We can also add static mappings using "ip dhcp snooping binding". But arp
inspection is not working with
static mappings using "ip dhcp snooping binding".




With regards
Kings
