At present, we are using a Cisco 2960g-48 port switch. I've attempted to use DHCP snooping and save the binding database to a location, either tftp: or flash to no avail. I have upgraded to the latest IOS (c2960-lanbasek9-mz.122-52.SE.bin). Still no difference. We are not using the DHCP option 82 information.
In our configs, we have:
ip dhcp snooping vlan 2-798,800-4094 no ip dhcp snooping information option ip dhcp snooping database tftp:/snoop.dhcp ip dhcp snooping database write-delay 15 ip dhcp snooping database timeout 15 ip dhcp snooping ip arp inspection vlan 2-798,800-4094
