We have read https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-configure-DHCP-Snooping-on-EXOS but still have some questions.
We have a core switch on which there is 1 DHCP server connected in a “Internal_Appliances” VLAN. Also on that VLAN is a “Desktops” VLAN that has a couple of desktops connected (unfortunately) as well as an uplink to the Edge stack where the rest of the desktops are connected. What we are trying to accomplish is to drop packets and send a trap if there ever was another DHCP server anywhere on the network. Do we just need to create a trusted server (specifying our DHCP server IP) on both the Internal_Appliances and Desktop VLAN on both the core and edge and enable dhcp snooping on all ports? If using a trusted IP do you still also need to use trusted ports in our scenario?
