How to get DHCP relay working with Foundry and DELL Powerconnect
Posted on 2009-02-23
So my issue is subnetting my network and DHCP
I have 3 DELL Powerconnect 3448 switches, 1 5324 Power connect and 2 Foundry FGS624P switches that are on order
I had 1 large /16 network which I have changed to a /24 network with the plan to subnet the floors with vlans and do the same for our VoIP phones and Video. I have managed to get VLAN's up and running and am using our Watchguard Firewall to route between the subnets. If I assign clients, servers and cameras different addresses with static IP's comms are all good. But the DHCP relay is not available on any of the DELL switches so I cannot get DHCP assigned addresses on the other vlans apart from vlan 1. Which is a major issue especially for the VoIP phones.
I am trying to figure out whether using the Foundry switches (which do support DHCP relay) as my routing device will fix this issue? i.e will the DELL floor switches pass on the packets with the DHCP discover tag on to the Foundry router or will it just drop it?
I have a feeling the answer is I need new switches to achieve this but hoping I can work around this. I obviously want to be able to assign DHCP addresses on all vlans.
