I have a Dell PowerConnect 7024P that has both VLAN 1 and VLAN 300 configured. VLAN 300 is used to support VOIP. The problem I'm having is that for some reason the DHCP server I have setup to allocate IP addresses to the VOIP phones is allocating addresses to the desktop machines. I'm confused why this would be happening since I did allocate and IP address for each VLAN interface in order to ensure the request would get handled correctly based on the subnet. So why does the DHCP server for VOIP hand out IPs to the desktop machines?
Voice VLAN 300
ip address 172.31.25.252 255.255.255.0
