How do i setup Windows DHCP work with VLANs on Cisco 2960x Switch

[Noor Muhammad]

Hi Everybody,

I have Windows server 2008 R2 DHCP Server . All Scope Created by Department Name and All System Mac Address has been Reservation on His Department Scope.

Now i am deploy Network Infrastructure.

Router 2911

Core Fiber Switch 3850S-S (Fiber Connectivity with Floor)

Multi layer Switch 3850T-L ( For Servers)

Access layer Switch 2960x

I have Plan Create Multiple Vlan by Department Names and i want my DHCP Server(Windows Base) Give IP of Users Systems as i have Reserve in DHCP Scope.

My Question is that = IS Cisco Switch VLAN Support Windows Base DHCP.

if it is Possible so how ?

On the switch where you are doing the routing between vlans you will have multiple SVIs ("int vlan <x>") and you just add a command to all the SVIs eg.

int vlan <x>
ip address x.x.x.x <subnet mask>
ip helper-address <IP address of DHCP server>  <--- this is the command you add

the DHCP server will then hand out IPs to clients and you should set the default gateway of the scope to be the IP address of the SVI.

You don't need to add that command on the SVI for the vlan the DHCP server is in.
