Re: Dhcp snooping And ARP-Protection
We do not use arp protection, so I cannot comment about that. We have basically the same architecture as you, and we have disabled option 82
no dhcp-snooping option 82

Re: Dhcp snooping And ARP-Protection
The Arp-protect feature we can use in the vlan context to protect the network gateway for this vlan, normally the interface vlan located in the core switches or fixed ports switches working as core switches.
You can limit the number of arp entries according to the size of vlan´s network /24 /23 /22 with the command
arp max-learning-num XXXX
to preserve memory and processing.
It is necessary configure arp-protection trust feature in the uplink to the switch where is the interface vlan or gateway for the vlan.
