I am attempting to configure dhcp-snooping with arp validation on a lab X450e-24p. DHCP snooping seems to work fine, I configure a trusted port (24) where the DHCP server is reached off of.
When I configure arp validation, I begin to get errors related to the default gateway of the network.
An ARP violation was detected on vlan port 24 violating IP violating MAC violation type Invalid IP-MAC Binding
I'm presuming this is because the gateway does not DHCP so a binding is never learned. Is the solution to this to create a static entry with this command:
"configure ip-security dhcp-bindings add"
Am I thinking of this correctly, is there any other technique?
