DHCP scope and printers?

Question

Created a DHCP scope with exclusion range for printers on the network, also created client reservations for each printer. None of the printers received a IP address from DHCP. How do I correct this?"

Answer 1

If printers are in exclusion range, they will not get it from the DHCP server.

You have to put the printers outside the DHCP range, and configure manually each printer, or put then into the DHCP server, and reserve the IP addresses by the MAC address of the printer. For DHCP to give a reserved address, it has to know what machine has connected, usually by it's MAC (network card) address.

Answer 2

Exclusion Range: The excluded IP addresses are definitely *not* assigned by the DHCP server; you need to assign IP addresses to your printers, manually.



For the Client Reservation you need

a) MAC (hardware) address

b) IP address

Maybe there is something wrong with IP address/MAC address.

Answer 3

Either use MAC addresses or create another instance of the DHCP server. Keep the DHCP boxes on separate VLAN interfaces ( logically) to make sure that devices stay on separate address space. keep in mind that there is no really good reason to keep these separate as they travel the same path. If you eventually will use softphones on PC you'll break you voice IP scheme anyway. Use VLANs and one dhcp scope and manage that way.

Answer 4

Delete the exclusion range. It is unnecessary. The reservations will take care of what you want.
