We have the following Situation:
VLAN 1 = DATA
VLAN 20 = PHONES
Windows Server 2012 - DC & DHCP - This is a VM
Cisco 3560 Switch
Basically, we need the port that the Server is plugged into to be able to process DHCP requests from both VLANS. Unfortunately, each port can only belong to one VLAN, and even if we set Voice-Vlan as 20 on the port, it does not hand out DHCP addresses. If we set it as a member of 20, we loose data connectivity. How do we go about doing this?
