GS108E-v3 DHCP VLAN

A couple of points ... First - network "best practice" dictates that all infrastructure devices be set to static addresses, so at least personally, I see no reason to select which VLAN the DHCP server should reside on, and for that matter, I'm curious as to why anyone would want to have more than one DHCP server (ok, maybe two, for redundancy purposes) on their network. Using these practices the only time the switch would need to get an address from the DHCP server is during the initial setup. Default gateway - as I'm sure you already know - the purpose of the default gateway is to specify the "gateway" that the device will use for "off network" communications - having a default gateway set comes in very handy for remote troubleshooting (as in fact does a static address). If you're running a small network, these might be "non-issues" for you, but as your network(s) grow(s), it becomes a lot easier to be able to manage it without getting up from your desk, or without driving across the city/flying across the country.
