Vlans not getting DHCP on 4506

[hornbeck]

Hello all,

We are trying to implement a 4506 into our system with Vlans. We are a windows 2003 network and have our dhcp configured for 4 Vlans.

We tested on port g2/4, the workstation cannot find a dhcp server, I get a 169.xxx.xxx.xxx number.

Below is the port configuration. Any suggestion or thought on how to get these Vlans to see our dhcp server is greatly appreciated.

interface GigabitEthernet2/3

description A&R

switchport access vlan 3

switchport mode access

!

interface GigabitEthernet2/4

description Apps

switchport access vlan 2

switchport mode access

!

interface GigabitEthernet2/5

description BO

switchport access vlan 2

switchport mode access

Thanks for your time and consideration,

Gary

What subnet is your DHCP server on? You will need a router to connect to the DHCP server with ip helper address specifed on the interface for your data subnet to point to the DHCP server.

Hi Gary,

Can you confirm your windows 2003 DHCP server is connected on which port and that port is configured for which vlan.

If you want you machines from different vlan to pick an ip address from DHCP server which is in one specific vlan then you need to have routing between all those vlans (intervlan routing) and the device where you configure intervlan routing you also have to configure

"ip helper-address " on your layer 3 interfaces configured for intervlan routing.
