I'm working at a client site that uses two seperate routers, switches (non Cisco) and ISPs for their VoiP and Data traffic. The only common connection between the two LANs is one Windows server that runs DHCP via a 2 port nic thats connected to each switch.
They're expanding into a new part of their building and a new Cisco SGE2000p has been installed. Two drops, one from each switch have been run into the expansion area. My goal is to segment the ports on the SGE2000p into two seperate VLANs, so that ports 1-12 connect to the Data switch and ports 13-24 connect to the Voice switch. I've tried this multiple times but I can't get DHCP traffic to flow over both vlans, it always ends up working on only one of the two, whichever is the first VLAN that's configured.
Here's my current config:
VLAN100:Port 1 connected to Data switch. Ports 2-12 untagged members, computers connected. Recieves DHCP from server.
VLAN200:Port 13 connected to VoiP switch. Ports 14-24 untagged members, phones connected. Doesnt recieve DHCP from server.
DHCP relay enabled and pointed to the DHCP server.
Both phones and data are on the same 10.10.10.0/24 subnet.
Neither VLANs have IPs assigned to them.
There are no VLANs on the 2 origional switches.
Where am I going wrong here?
I've attached a diagram and your help is greatly appreciated!
A little more detail about how the new SGE2000p is configured might be helpful, especially how DHCP relay is set up. But as I read this description I believe that one problem may be trying to have the same subnet on both VLANs.
