Yeah server 2012 r2 box doing it. You've got my thought juices flowing... Wondering if it's some sort of weirdy problem with the Dell vrtx switch and the trunking between the nodes and that switch thsts fucked with Vlan tagging somewhere. Might spin up a quick box on a vm to try out, isolating that switch.

Good guess on the netgear config then! :lol:
I'd certainly rule out the DHCP itself, is it a windows box doing it?

That is exactly what I have configured. I didn't try that Kyle, I'll give that a go.
interface vlan 32
ip helper-address 10.5.6.171 dhcp

Do clients in VLAN6 get a DHCP address when connected? (DHCP setup might just be knackered :P )
I'm not sure what the Netgear config looks like for IP Helper addresses, but you normally need an entry against every VLAN saying something like
interface VLAN 6
ip helper-address 192.168.32.1 (IP address of DHCP server)

I managed to fuck DHCP completely yesterday by playing, nothing at all even on VLAN 1 would respond to a DHCP request :lol:

Done and done, has always been like that :(
I always set the vlan interface to the last usable address in the vlan's subnet and point the DHCP server to that gateway for that subnet, got exactly the same setup at another school using Meraki which works no problem, just can't get the settings on the Netgear stuff right :mad:

has the layer3 switch got static IP addresses set on each vlan
Set the DHCP scope up with the gateway of the static IP of the VLAN

Trying to VLAN up a network, mostly going nicely. I've got inter-vlan routing sorted etc, all working lovely if I manually assign an IP to two clients on different VLANs and ping each other.
My setup is a bunch of L2 switches with all the VLANs on every switch. All of the uplink ports have all of the VLANs tagged on them. Clients in a VLAN have a PVID of that VLAN number and the port is untagged on that VLAN. Every other port is untagged on VLAN 1 (that won't be used once the transition is done). There's a M7100 at the middle with L3 routing turned on, all ports to this are tagged with every VLAN (and untagged with VLAN1) as all the switches plug into this. I've moved my DHCP server to VLAN 6 and put a client in VLAN 32. I've turned on every DHCP L2 relay option I can find and it's still not working. Give the client an address in VLAN 32 and I can ping the DHCP server not a problem!
Anyone got any advise?
Thanks :wave:
