I am trying to inspect vlan 100 using Dynamic ARP inspection feature. My fwsm blade provides dhcp services to Vlan 100 users. Below is my configuration.
ip dhcp snooping vlan 100
ip dhcp snooping
ip arp inspection vlan 100
vlan 100,200,300

interface GigabitEthernet0/1

I keep getting the following message and denies all access to the network
%SW_DAI-4-DHCP_SNOOPING_DENY: 1 Invalid ARPs (Req) on Gi0/5, vlan 100.([0016.d3b5.30a4/10.0.0.4/0000.0000.0000/10.0.0.1/07
Please suggest if I am missing anything.
