I have one DHCP server in default VLAN. I have multiple VLAN (voice) and I want the ports on the VLAN to grab dhcp addresses from additional scopes. I know that I need to use IP Helper, but all instructions refer to an IP address assigned to your VLAN. I don't see where to do that...only IP address assigned is the siwtches IP.
if so, possibly you could turn on more interfaces, ip/place them onto ports where native vlan equals the Vlan you're trying to DHCP for, Then as your VOIP devices start asking for DHCP, there should be an issue? this might be overthinking though. Another question, can DHCP in it's current config hear dhcp requests from your clients' devices on all Vlans?
From a physical senses yes.DHCP could hear all requests. But VLANing the VOIP, wiht a port that only has a Phone on it...logically DHCP can't not hear teh requests. But it is my understanding that have a VLAN use a different scope and subnet, you need to logically use an IP Helper...
