DCHP Snooping across multiple trunked switches.

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.

Re: DCHP Snooping across multiple trunked switches.

Hi

If you are enabling the dhcp snooping on all 3 switches including middle switch, you have to put the all the uplinks(or trunk links) and connection to dhcp server to be trusted.

HTH.
