When implementing DHCP snooping on 2960 switches, if the switch sits "in the middle" of two other switches, such as there is an edge switch which is trunked to a middle switch that is finally trunked to another switch, do I have to set the two trunked ports on the "switch in the middle" to trusted to make sure all DHCP traffic goes from the core network to the edge switch?
It seems logical that this must be the way it has to be implemented throughout the network, but I want to make sure.
