Wireless Access

Hi,

I've created initial VLAN and 1 ssid (Corp). Then I've created a dhcp scope for that VLAN.

Basically my wireless clients are still getting a dhcp address from our domain controller and not the allocated range on the Aruba wlc

What am I missing ?

Many thanks

did you do also on the controller,

service dhcp

thanks, but still no joy

Any ideas

If there are multiple DHCP servers for a network available (in your case the controller and Windows), the first one to respond is where clients will get an IP address from. 

First confirm DHCP is setup properly on the controller:

show ip dhcp database

show ip dhcp statistics

show ip interface brief (the controller needs an IP on the VLAN)

Second, if you cannot turn off the scope no the Windows server, you can configure a DHCP helper for the VLAN in question to try and direct the request to where you want.

interface vlan XX

ip helper-address x.x.x.x (IP of controller)

Thanks but still picking up from the domain controller

see attached

many thanks

Type "show user-table verbose" and see what VLAN# the user is ending up in.  It would be in parentheses in the last column.

it's ending up in VLAN 1 which is correct

thanks

Ah yes thanks

So we can't issue a separate DHCP pool on the default vlan ?

The network on the scope needs to match that of your vlan interface, otherwise it won't respond.

If you want to keep using the Windows server for other devices, you should put exclusions in place on both to ensure there is no overlap and ip conflicts.
