DHCP for Voice and Data VLAN How to implement?

Hi guys,

     Im implementing a CUCM 8.5 and a Catalyst 4500 as the core switch. My questions are the following:

1. Which is the best way to implement DHCP on this scenario?

2. Im planning to create dhcp pools on the Catalyst 4500, but how do you implement on the 4500 to get dhcp for the phones on a vlan and dhcp for computers on another vlan? Should I configure thw dhcp pools? Thanbks in advanced.

Yes, based on the VLAN it will pick up, phones will use CDP to pickup voice VLAN and will use DHCP scope for that VLAN network.

1. If you want to use the 4500 as DHCP server, simply add the scopes to add, there are plenty of documentation on building these and it is very straight forward. here is one such link:

2. You build separate pools that reference separate networks which will match the vlan interface addressing and as long as they are on the same switch no address helper is needed.

Thanks Chris. One question, how does the phone and the computer connected to it knows which pool is for data and which pool is for voice?
