Sorry Jon I changed my post last minute So, 1 /24 VLAN per floor, then you split that VLAN into 2 /25. I missing something again here, if you create the vlan on the 6500 "ip address 192.168.1.1 255.255.255.0. How are you then splitting this up into 2 /25? Sorry to be a pain. Jamie

Oh I see from the DHCP server, is that correct? Jamie

That is the scenario I would like to put in place, its just convincing my colleague now!!Jamie So, 1 /24 VLAN per floor, then you split that VLAN into 2 /25.

Instead you would have for example 2 vlans per floor - vlan 10 & 11. On the 6500 switch int vlan 10ip address 192.168.1.1 255.255.255.128 int vlan 11ip address 192.168.1.129 255.255.255.128 Don get too sidetracked with /24 vs /25. There is nothing wrong with a /24 and a lot of networks use this as standard. Jon

  ahh, that makes more sense now, I read it that you were allocating 1 vlan per floor and not 1 subnet. Makes perfect sense, wish me luck! Jamie
